The hard internship life ended inadvertently. You must have learned a lot of new methods. Let's study and write an internship summary together. However, I believe that many people are in a state of no clue. The following are my carefully compiled summary essays (6 selected essays). Welcome to reading. I hope you like it.
Summary of Coal Mine Practice Mining Class 1 Time flies. In a blink of an eye, it has been one year since August of 20xx, and the internship period is fleeting. In this year's work and study, from a college student who just left school and only knows theoretical knowledge to a novice with almost no work experience, he can combine theoretical knowledge with field equipment, give full play to the practical application of knowledge, and be able to complete the tasks assigned by the leaders relatively independently. Such a great change is the result of the careful teaching and training of the department leaders and the care and help of the masters. Here, I need to say thank you to the department leaders and masters. It is you who have completely integrated me into the family of "standardized management, orderly operation, performing their duties, being conscientious, working happily and being like a family" in Hatu Gold Mine.
1, internship
After I came to Hatu Gold Mine, the first unit I went to practice was the locksmith's room in a mining area. The fitter's main job is to maintain and repair equipment. When I first entered the locksmith's room, I didn't quite understand what the locksmith meant. Now I really admire the locksmith. They can overcome difficulties and accomplish tasks well in any working environment. They often have to go down to more than 500 meters underground and work in dark mines and dark and wet blind wells, which is not easy.
Under the guidance of the masters, after four months of routine operation of welding guns and oxygen cutting guns in the locksmith's room, I have basically mastered how to weld and cut. Also understand the essence of electric welding, the composition of electric welding machine and the composition of covered electrode; Learned to choose the kind of covered electrode.
As an intern, I also want to go down and help the master. It's a bit risky to go down the well for the first time. I also learned a lot in the underground: starting from the bottom of the roadway-leveling the protruding part in the middle of the roadway; The practice of supporting logs in roadway pillar filling-hidden danger of roof caving: roadway enlargement-shovel the ore on both sides of roadway inward, increase the width of roadway, and affect the access or transportation of vehicles. Underground tunnels extend in all directions. You won't get lost if you don't follow the master when you go down the well for the first time. Now learn to look at the sign, look at the direction of the fork tip of the track and follow the track. We have a clear understanding of the internal resistance of the tank, guide wheel, kiln platform, coke pusher and so on. Another thing that impressed me was the cutting machine. It will be dangerous if the cutting machine is not operated properly. As for the impression, it is because I cut steel bars with a cutting machine for three days in a row.
The four-month locksmith internship will soon be over. Under the guidance of the master, I have mastered some skills through some hands-on practice. In these months of practice, I have a certain understanding and profound experience of welding operation and other common sense. I learned a lot of knowledge that I can't learn in class and benefited a lot.
2. Factory selection practice
I finished my mining practice, and my second practice unit is a 500t concentrator. There I came into contact with neutralization filter press plate frame, oxidation filter press plate frame, cyanide filter press plate frame, leaching, slurry mixing and mechanized workers. I have worked in the plate and frame of neutralization filter press for three and a half months, and I have a clear understanding of its technological process.
Working principle of plate and frame filter press;
The hydraulic pressing mechanism of the filter press is composed of a hydraulic station, an oil cylinder, a piston, a piston rod and a Havlan Card hydraulic station with the piston rod connected to a pressure plate, including a motor, an oil pump, an overflow valve (pressure regulating) reversing valve, a pressure gauge, an oil circuit and an oil tank.
When the hydraulic compactor is pressed, the high-pressure oil is supplied by the hydraulic station, and the cavity of the component composed of the oil cylinder and the piston is filled with oil. When the pressure is greater than the friction resistance of the pressing plate, the pressing plate slowly presses the filter plate. When the pressing force reaches the pressure value set by the safety valve (indicated by the pressure gauge pointer), the filter plate, filter frame (box) or filter plate (box) is pressed, and the safety valve begins to unload. At this point, the power supply of the motor is cut off, and the pressing action is completed.
When hydraulic compaction is automatic pressure keeping, the compaction force is controlled by electric contact pressure gauge. Set the upper limit pointer and lower limit pointer of the pressure gauge to the values required by the process. When the compression force reaches the upper limit of the pressure gauge, the power supply will be cut off and the oil pump will stop supplying power. Due to possible internal leakage and external leakage in the oil system, the compression force will be reduced. When the lower limit pointer of the pressure gauge is reached, the power supply is switched on and the oil pump starts to supply oil. When the pressure reaches the upper limit, the power supply will be cut off and the oil pump will stop supplying oil to ensure the circulation in the process of filtering materials.
Flushing method: When plates and frames need to be washed, sometimes there are unidirectional flushing and bidirectional flushing, as well as undercurrent unidirectional flushing and bidirectional flushing. Open-flow unidirectional washing means that the washing liquid enters from the washing liquid inlet hole of the thrust plate in turn, passes through the filter cloth and then passes through the filter cake, and flows out from the non-porous filter plate. At this time, the outlet nozzle of the perforated plate is in the closed state, while the outlet nozzle of the non-perforated plate is in the open state. Open-flow two-way washing means that the washing liquid enters the hole from both sides above the thrust plate and is washed twice, that is, the washing liquid is washed from one side first and then from the other side, and the outlet and inlet of the washing liquid are diagonal, so it is also called two-way cross washing. Underflow one-way washing means that the washing liquid enters the porous plate from the washing liquid inlet hole of the thrust plate in turn, passes through the filter cloth and then passes through the filter cake, and flows out from the non-porous filter plate. Undercurrent bidirectional washing is that the washing liquid enters the holes of two kinds of washing liquid on both sides above the baffle twice, that is, washing is carried out from one side first and then from the other side, and the outlet of washing liquid is inclined, so it is also called undercurrent bidirectional cross washing.
The internship in the concentrator gave me an intuitive and clear understanding of the gold smelting process. I only know that gold is a soft, golden yellow and corrosion-resistant precious metal. Gold is one of the rarest and most precious metals. Now it is discovered that the ore in is dark gray, and the precious gold out is shining and has gone through many complicated processes. After studying mineral processing, I have a clear understanding of gold smelting.
3, kilometer well practice
My third internship unit is Qianmijing. I'm still in the locksmith's room. I worked as an intern in the locksmith's room for a period of time before, and I was familiar with the locksmith's work, so I quickly integrated into the big family of Qianmijing.
The mining time of the kilometer well is not long, so many equipments are new and some infrastructures are not perfect. The workers in the kilometer well are very hard. They often have to work for more than ten hours and get off work late. Underground is also very frequent. Because thousands of wells are new equipment and infrastructure, I still have a lot to learn, which also gives me more learning opportunities. I will adhere to the spirit of hard struggle and devote myself to the construction of a thousand meters well.
4, internship summary
The past year has been a year of continuous learning and enrichment, and a year of active exploration and gradual growth. This year, I realized from my work and study that the spirit of doing and loving one line has also made me grow.
I realize that there is still a long way to go and there is still too much to learn. I will continue to study hard and cherish the learning opportunities in the mine before I take office. No matter what post I am assigned to in the future, I believe this knowledge will be a huge intangible wealth. Finally, I sincerely thank Caiyi, the factory selection, the Qianmijing, the leaders of Hatu Gold Mine, every master and colleague around me, and everyone for their concern and training.
I also know that graduation is only a small step in learning, and society is the real university. In the future work, I will try my best to find my own position, do my best to contribute to the company, create real wealth for the company, and at the same time seek greater progress for myself.
Summary of Coal Mine Practice Time flies in Mining Class 2. Before I know it, I have been working for one year. I came to Changgou Company of Yangmei Group, and gradually grew from an ignorant student to a qualified employee. During this period, I can't do without the kind care of the leaders and the kind guidance of the master. I worked hard to improve my ability in all aspects, and I joined the ventilation team, and made great progress in political thought, theoretical study and work practice. At the same time, I also realized the happiness brought by work. I will summarize my work during my internship as follows:
First, study political thought.
During my internship, I deeply realized that the ventilation team is a collective that stresses learning, innovation and unity. In such an atmosphere, only by maintaining a high degree of ideological consistency with the team leaders and being self-disciplined and positive can we integrate into this group. As a fresh graduate, I have no social experience and still have a lot to learn. So I need a correct attitude and keep my mind ahead. In my usual work and life, I actively participated in the life of Party organizations and all kinds of study, cherished the opportunity of collective study, and further improved my political and ideological awareness and theoretical level.
Second, work and study.
I remember last June 5438- 10, when I first came to Changgou Company under the leadership of Minister Yao of Human Resources Department. After making some simple arrangements, I immediately put myself into pre-job training. During the pre-job training, I systematically understood the production situation and general direction of our company.
After entering the ventilation team, Secretary Li of the Party branch of the ventilation team told me the nature of ventilation work, from which I learned that the work carried out by the ventilation team is closely related to production and is based on various rules and regulations. I started with learning all kinds of ventilation rules and regulations, and became familiar with the work flow of each type of work area. After signing the mentoring agreement, I worked as a gas inspector under the leadership of Master Yu, and now I have mastered the work flow of gas inspectors and the use of tile detectors and carbon monoxide detectors. I worked as a tile inspector for two months and worked as an intern in rotation, and came to the technical group of ventilation department. Under the training and leadership of the ventilation technical supervisor, I learned the use of ventilation technical instruments and the compilation of procedures and measures, and now I can complete the work independently.
Third, self-evaluation.
1, personal performance
Through one year's internship, my thoughts have made great progress and matured gradually. From a fresh graduate to an employee of ventilation department, I feel that things are no longer one-sided, I can work well, and I am diligent and studious. In this year, under the careful care and guidance of team leaders and colleagues, through their unremitting efforts, all aspects have made certain progress. I remember when I first started my internship, I was very worried about how to do a good job and how to get along with others. However, the company's harmonious working atmosphere and United corporate culture made me quickly complete the role change.
2. Know your own shortcomings.
After this year's internship, I gained a lot, but I also realized my own shortcomings. At work, sometimes they are careless and not careful enough, and the officers are cautious, so that they are timid; In life, I don't have high demands on myself, and some bad habits at school have not been completely corrected; In writing, the foundation is weak, there are few things in my mind, and I need auxiliary tools when writing, so I can't finish writing independently.
Unconsciously, I have spent a year in my social post. This day of this year is a transitional period from a lush campus to a compound society, and it is also an important turning point in my life. Practice is not only important but also unique. It is through practice that I gradually mastered how to apply the theoretical knowledge taught by the school to practical work, so as to gradually change students' impetuousness and immaturity, really get in touch with this society, gradually integrate into this society, and realize my first step towards social independent growth.
Summary of coal mine practice in mining class Three or four months' practice life has ended like running water. Looking back on the internship life, it is very profound and rewarding. During my internship, I took advantage of this rare opportunity to work hard, be strict with myself, consult the older generation of underground technicians with an open mind, use my rest time to learn some relevant knowledge outside the textbooks, master some coal mine-related skills, further consolidate my professional knowledge and lay a solid foundation for future work. I must integrate theory with practice, not be absent from work during my internship, and listen carefully to the leadership. It has been well received by unit leaders and colleagues.
Three generations of my family are engaged in coal mine work. I want to be as serious and eager to know my work as my grandfather and father. Through this internship, I have a deeper feeling for the coal mine. I want to join the coal mine work at once and become an excellent coal mine technician.
Zhuolu Mining Company of Zhangkuang Group is located in the mining area of XX county west15km, with convenient transportation. The mining area highway leads to XX county, which is 45km away from Xiahuayuan to Guangling Highway, Jingzhang Highway and Jingbao New Security Station, 30km away from Xiahuayuan Station, 80km away from XX City and 180km away from XX City.
Zhuolu Mining Company currently has three production mines, namely Xishan Slope Well, Huangtuwan Well and Xisiwan Well. With the development of "safety first, prevention first, comprehensive management and overall promotion", Zhuolu Mining Company has embarked on a new road of industrialization, joined a large group and become a state-owned key coal mine.
On February 25th, I started my internship in Xishanpojing of Zhuolu Mining Company.
First of all, understand the main system of Xishan slope well. There are three levels of Xishan slope well hoisting, namely 4 10 level, 200 level and 85 level, which are multi-level train hoisting. Inclined dump is used in all three horizontal bottom yards, transportation alleys are used as main shaft storage lines, each level is equipped with water tanks, and the ground fire pool is arranged outside the main inclined wellhead, and the water capacity of each water tank is about 300m3. The normal water inflow of the mine is 30m3/h, and the maximum water inflow is 40m3/h. ..
In the underground, we practiced for 8 hours with the old workers in 802 coal mining face. Because it is the second working face of No.8 coal, it is called 802 coal mining face.
The working face adopts sg420/22 flexible scraper conveyor at one time, then it is transported by sg620/40t flexible scraper conveyor, enters the coal chute, is loaded by 85 horizontal roadway, and then the 1t car is towed to the external 85 horizontal yard by 2.5t electric locomotive, and is lifted and transported by the underground auxiliary main winch. The working face adopts backward coal mining, with the cycle progress of 1m, and adopts the operation mode of "three shifts of coal mining, accurate mining while mining", supported by single hydraulic prop and cantilever beam. The maximum roof control distance is 4m, the minimum roof control distance is 3m, and the caving step is1m.. The goaf treatment method is full caving method. The blasthole layout in the working face adopts three-hole blasting, with the blasthole depth 1.2m, the bottom hole spacing 1m, the top hole distance from the coal wall 1m, the horizontal included angle between the blasthole and the coal wall of 70-80 degrees, the roof inclination of 5- 10 degrees, and the bottom plate distance from the top plate of 0.3m-0.4m. The working face is equipped with "gas electric locking" device, and kj86 gas monitoring system is adopted. The working face is equipped with two monitoring probes, one is located in the coal mining face, with alarm concentration greater than or equal to 1%, power-off concentration greater than or equal to 1.5%, and re-power concentration less than 1%, and the other is located in the air return roadway and the top of the roadway in the coal mining face. Set the alarm concentration greater than or equal to 1%, the power-off concentration greater than or equal to 1%, and the power-on concentration less than 1%. The control scope covers all non-intrinsically safe electrical equipment in the working face.
The mining technology of the working face is: drilling-blasting-hanging beam-mining-moving pillar.
The upper and lower exits of the working face are supported by 4 pairs of 8 beams, and the single hydraulic prop is supported in advance, with double rows10m and single row10m. When the pressure is high, it is supported by one beam and two columns.
The blasting mode is MHB- 100 blaster, and the connection mode is series. The types of work in the working face are: blaster, gas worker, prop pulling worker, slipper, driller, coal loader, slipper, etc.
Two months later, I worked as an intern in the safety supervision ventilation area, mainly mastering the air distribution and ventilation facilities construction.
The air volume distribution is based on the air volume required by the working face, excavation and each cavern, and the effective air volume rate must reach 85%. Xishanpo well is a gas mine, and the relative gas emission is more than 65438+1100m3/t.
Ventilation is divided into five groups: gas crew group, blaster group, underground monitoring group, dustproof group and ventilation group. Five kinds of drawings are drawn in the ventilation area, namely: dust prevention system diagram, fire prevention system diagram, disaster avoidance road map, monitoring system diagram, ventilation system diagram (ventilation network diagram) and Xishan inclined shaft ventilation network diagram.
After ventilation, we know the installation of flameproof water shed, which is divided into main flameproof and auxiliary flameproof. The main flameproof device is installed in the main air inlet and return roadway, between mining areas, between coal seams and between levels. The auxiliary flameproof device is installed between the coal mining face and the digging well, and between the coal mining face and the series working face.
Underground dust prevention measures include: mixing drilling, spraying water and soaking mud. But also know the installation of high and low gas mine probes.
During the internship, I also edited the Safety Technical Measures for Series Ventilation and the Safety Technical Measures for Roadway Penetration for the safety supervision ventilation area. For example, when two roadways are interconnected, one working face must be stopped when blasting and mining are 30 meters apart, but the wind cannot be stopped. It is necessary to set up a warning guard to block people, and then simply study the direction of airflow when connecting. The place where the damper or wind window is installed should be prepared, and the connection point must be supported by a solid bracket. You also need to draw a schematic diagram of the ventilation system before and after.
The fresh airflow direction of Xishan inclined shaft: main inclined shaft-main underground well-secondary main underground well -85 horizontal west lane -802 coal mining face air inlet lane -802 coal mining face polluted wind;
802 working face -802 working face return air lane-secondary auxiliary underground well-auxiliary underground well-auxiliary inclined shaft-ground.
I use my professional knowledge to consolidate my theory through practice and practical work. I should have the spirit of hard work and always ask and learn from old technicians. I learned a lot of professional knowledge in this mine. There are many more, so I won't talk about them one by one. I will continue to study in my future work. I promise to live up to the expectations of teachers, parents and mine leaders. Now that you have studied this major, you can't learn it for nothing, you have to learn it in one line. I believe I can make great achievements in my future work.
Summary of coal mine practice The time of mining class four has passed, and this practice is coming to an end. This graduation practice is a transition period for me to really enter the society, and it is a more comprehensive and in-depth on-site professional practice after learning professional knowledge. During the internship, I got the care and help from the leaders of various departments and schools in the mine, and I will successfully complete all the tasks of graduation internship. Now, I will summarize some knowledge I learned during my internship as follows:
First, during the internship of the technical team, with the guidance and help of safety engineers and technicians, the relevant knowledge of mine survey was consolidated; Understand the use of total station in underground; Comprehensively review and personally practice the arrangement and calculation of measurement results (data); Familiar with and practice drawing measurement results (data) on the plan or elevation of mining engineering; Know how to set the center line, waist line and orientation underground; Check whether the roadway quality meets the design requirements; Read and be familiar with the operation procedures of coal mining and tunneling faces; Read and collect relevant information such as mine geology and production technology.
Secondly, during the period of safety ventilation management department, I read a lot of books about five major disasters in coal mines; Understand the training, examination and certification of coal mine special operations; Understand and read some laws and regulations on coal mine safety production; Read the coal mine disaster prevention plan and accident emergency rescue plan; Understand the responsibilities of various departments and offices in the mine; Understand mine ventilation, anti-wind plans and measures, etc.
Thirdly, during the period of following the leading technicians down the well, I have a further understanding: the dust and noise in the coal mining heading face are large; Because of the long mining life and long roadway, it takes 1 hour to reach the working face with the lowest mining level. Head-on narrow construction conditions are bad. We have learned a lot from the road we have traveled. For example, the mining face seen in the textbook is so flat, spacious and clear, but the situation at the scene is definitely not so clear. People who have no spatial thinking ability can't figure out the direction at all.
Summary of coal mine internship in mining class 5 Time flies, and it has been half a year since the internship in a blink of an eye. This is a precious experience in my life, and it also left me with beautiful memories. During this time, you have given me enough tolerance, support and help, so that I can fully feel the hearts of the leaders, the heroism of Kowloon people who "can't see the rainbow without experiencing wind and rain" and the difficulties and firmness of coal miners. While I am in awe of you, I am also surprised that I have the opportunity to become a member of the Kowloon Mine.
In the past six months, under the careful care and guidance of leaders and colleagues, through their unremitting efforts, all aspects have made certain progress. I remember when I first started my internship, I was worried about how to do a good job and how to get along with others, but the relaxed and harmonious working atmosphere and United corporate culture made me quickly complete the role change. Now I will make the following report on my work.
During my internship, I took advantage of this rare opportunity to work hard, be strict with myself, consult leaders and colleagues with an open mind, study political theory, policies of the party and the state, study laws and regulations, and use my spare time to study some related knowledge beyond the contents of textbooks, master some basic professional skills, further consolidate what I have learned, and lay the foundation for truly going to work in the future. During my internship, I tried to put the theoretical knowledge I learned in school into practice and try to combine theory with practice. During the internship, I can abide by the work discipline, don't be late, don't leave early, and conscientiously complete the work assigned by the leaders, which has won unanimous praise from the leaders and colleagues of the internship unit, but I also found many shortcomings of myself. Through this internship, we have learned a lot that we can't learn in textbooks, and have a deeper understanding of underground production in coal mines.
The so-called thousands of books, Wan Li Road. A theory that has not been tempered by practice is always an armchair strategist. Practice has been regarded as the only way to grow since ancient times. In the process of production practice, I really walked into the big classroom of society, experienced a completely different world from the past, increased my knowledge, broadened my horizons, and laid the foundation for stepping into society in the future!
Summary of coal mine practice The practice life of class six in mining is coming to an end. Looking back is very profound and rewarding.

Through this internship, we have learned a lot that we can't learn in textbooks, and have a deeper understanding of underground production in coal mines.
The so-called thousands of books, Wan Li Road. A theory that has not been tempered by practice is always an armchair strategist. Practice has been regarded as the only way to grow since ancient times. However, when you take the first step in practice, you will find that this road is never broad and long. The rules here don't allow you to break them casually, but you should also grasp the direction of progress yourself; Not as colorful as imagined, nor as unfathomable as legendary; It's simple and clear here, but it also hides waves. This is the real source of knowledge.
I think Pingzhi College is a transitional zone from school to society. It should not only teach students knowledge, but also teach students survival skills and skills. Probably based on this, the school will arrange us to carry out social practice. As a production worker who just went down the well, although I don't have solid professional knowledge of coal mines and my views on various issues are more limited to the stage of perceptual knowledge, I really entered the big classroom of society in the process of production practice.
