Technical Paper of Coal Mine Electrician Technician 1 Installation and Construction Technology of Coal Mine Electromechanical Engineering
At present, the installation and construction technology of coal mine electromechanical engineering is becoming more and more important, because with the development of coal industry, it is necessary to implant modern technology into traditional coal industry, which is beneficial to the long-term development of coal industry. Therefore, in the future installation and construction of coal electromechanical engineering, technological innovation is very important, especially coal electromechanical engineering includes many projects, which need to be analyzed one by one, such as drainage engineering, electrical engineering, ventilation engineering and so on. Therefore, many projects need scientific management to maintain a benign configuration.

1 analysis of construction management problems of coal mine electromechanical engineering
For the mechanical and electrical installation project, the management work is relatively trivial, and the problems exposed in the management are also relatively trivial. The following will analyze the problem management in various projects.
1. 1 drainage engineering construction
The problems existing in drainage engineering construction are mainly reflected in two aspects:
First, the material quality is not up to standard. During the construction of this project, the common problem is the quality of drainage pipes, because it is the main material used in this project. If it has problems, the project itself will encounter huge quality problems. Testing standards are not strict, suppliers are greedy and produce some fake and shoddy materials, so the problem is more serious. Problems in drainage pipes will lead to serious consequences, such as pipeline leakage and pipeline rupture.
Second, management and construction are lack of standardization. In addition to the quality problems of the above materials, there are also problems of irregular management and construction operation in drainage engineering. First of all, in terms of management, due to the limited level of construction management personnel, lack of professionalism and lack of scientific and normative project management, it will lead to chaotic project management and slow construction progress; Secondly, the construction personnel have low professional level and lack of training, so the construction operation lacks standardization, which will seriously affect the project quality; Finally, drainage engineering is a project that requires high professional skills. If the management and construction personnel can't meet the requirements, there will be problems in the project.
1.2 ventilation engineering construction
The problems existing in ventilation engineering construction are reflected in three aspects:
First, the construction process lacks safety management and safety operation awareness. In the construction of any project, safety is the most important and should always be put in the first place. However, in the ventilation engineering construction of coal mine electromechanical engineering installation, the lack of safety awareness is still a very serious problem, which will seriously affect the safety production of coal mines, and many coal mine accidents are also caused by this reason.
Second, the professional skills of construction workers are poor. The quality of ventilation engineering construction personnel is also very important. Imagine how a project can have a high-quality project without high-quality construction personnel. The quality of the project depends largely on the quality of the construction workers. At present, one of the problems in ventilation engineering is that construction workers lack professional skills, are slow to get started, and can't finish the project independently, which slows down the progress of the project and affects the quality of the project.
Third, there is a lack of follow-up testing and debugging after the construction is completed. Follow-up inspection is very important. It is the key to test the ventilation effect of the project through trial operation, which is convenient for debugging and is the key to test the quality of the project. At present, the attention to this work is low.
1.3 electrical equipment construction
In coal mine mechanical and electrical engineering, electrical engineering construction is a relatively professional project, so there must be professionalism in the construction process, including the professionalism of staff, managers and supervisors, which reflects the scientific and technological content of the project. But there are still many unprofessional problems.
First, the size of the foundation steel does not match the size of the distribution cabinet, and the size and length of the former are often greater than the latter. And if the size and length of power distribution cabinets in rows are greater than 6m, the size of foundation steel needs to be maintained at 6? 0.3m However, in the actual safe construction process, it is difficult to match the size of the foundation steel and the power distribution cabinet, so it is impossible to set sockets at both ends of the channel of the power distribution cabinet to keep in touch with the electrical room as required. Even if the outlet of the channel can't meet the requirements, there are great errors in the installation of the distribution cabinet and the foundation reinforcement.
Second, the bending radius of the installation conduit is too small. According to the technical standards in the industry, if the installation conduit is buried underground, its bending radius should be at least 12 times of the outer diameter of the conduit. The reason is that if the bending radius of the installation conduit is too small, the tension of the conductor will be greater and the insulation layer will be seriously worn.
2 to solve the problems in the construction and management of coal mine electromechanical engineering countermeasures
The key to improve the construction technology is to find the problem, suit the remedy to the case and solve the problem fundamentally. The above has specifically analyzed the specific problems existing in the three projects, and the following is an analysis of how to solve these problems.
2. 1 standard drainage construction operation standard
Aiming at the problem of nonstandard material quality and operation in drainage construction, the solutions are as follows:
First, improve the quality of purchased materials. The quality of building materials depends on procurement, so to improve the quality of drainage pipes, we must work hard on material procurement. First of all, the purchase should be strictly controlled, and a detailed purchase approval form should be submitted before each purchase, and the purchase can only be carried out after strict examination and approval; Secondly, it is necessary to set up a professional purchasing team to improve their purchasing ability through strict screening and training, and each purchase is carried out by them; Finally, it is necessary to form a scientific procurement assessment mechanism, do a good job of assessment, and improve the enthusiasm of employees.
The second is to improve the standard operation ability of construction personnel through training. Due to the diversified sources of coal mechanical and electrical engineering construction personnel, the general education level is low, and everyone sells physical strength, so the low professional quality is understandable, which requires enterprises to improve safety awareness and do a good job in training, which is also a part of human resource management, and do a good job in guiding and educating employees.
2.2 Make a perfect debugging scheme for ventilation engineering.
Ventilation engineering determines the safety of the whole coal mine electromechanical engineering. Generally speaking, coal mine accidents are caused by poor ventilation. Specifically, efforts should be made in the following two aspects.
First, do a good job in safety education. Safety is the core of coal engineering. Every year, many coal production safety accidents have caused serious harm to their families. In order to minimize the harm, safety accidents must be eliminated from the source. So where is the source? In fact, it is consciousness. Many safety accidents are caused by carelessness, so we should work hard from the awareness of safety production and do a good job in safety education.
The second is to do a good job in the follow-up supervision and inspection of construction. As mentioned above, the follow-up inspection of ventilation engineering is sloppy, so it is necessary to strengthen the supervision of this work and strictly supervise the personnel in charge of this work to do a good job in the follow-up inspection and trial operation of ventilation engineering.
2.3 Strict management of electrical equipment construction
From the foregoing, it can be seen that the main problems in the construction of electrical equipment in coal mine electromechanical engineering are the size of foundation steel seat and the bending radius of installation pipe, which need strict management. First of all, electrical equipment construction personnel need to strictly cooperate with inspection and supervision. If the construction design requirements of coal mine mechanical and electrical engineering need to be changed, it is necessary to notify the equipment orders department in writing to change the design scheme, and at the same time notify the owners to strive for their understanding and support for the scheme change. Strictly check the fixing effect of foundation steel and transformer panel to ensure that the actual dimensions of foundation steel and power distribution cabinet are highly matched and meet the requirements of foundation steel and power distribution cabinet.
3 Conclusion
In coal production, electromechanical installation is an important link, because it seriously affects the safety of coal production, especially ventilation engineering. Through the analysis of the whole paper, we know that there are still many shortcomings in coal electromechanical construction at present, and there are more or less problems in three specific projects. Subsequently, the article also puts forward some measures to solve the problems and improve the existing construction level. It is believed that through the joint efforts of peers, frequent coal safety production accidents will be reduced.
