In recent years, the industrial upgrading of the coal industry has become more and more obvious, and there is a new demand for high-yield, high-quality and efficient production technology. In the context of the urgent need to improve the productivity level, the emergence of mechatronics has brought hope to coal mining enterprises, and it has become a widely used production and operation mode for major coal mining enterprises. Coal mining industry is a traditional pillar industry in traditional industries. Today, with the rapid rise of emerging industries, it is necessary to continuously improve the production operation mode and introduce the most advanced production technology and equipment to reduce the labor intensity of workers, improve work efficiency and production quality, and then improve the economic benefits of enterprises.
1 Overview of mechatronics
Technical principle of 1. 1
Mechatronics is a technology matching system widely used in coal mine production activities. It integrates advanced technologies such as power electronics, information communication and computer control, and draws on the technical essence of microelectronics and intelligent software technology to realize the mutual penetration and combination of different technical forms. Electromechanical integration represents the crystallization of advanced production factors in coal industry technology. With its advantages of systematization, intelligence, miniaturization and humanization, it is widely used in the production field of coal mining enterprises and brings rich benefits to major enterprises. While realizing the optimization and upgrading of traditional industries, applying advanced mechatronics technology to coal mining machinery can also save energy and reduce consumption and achieve the production goal of sustainable development.
The development of 1.2
China's mechatronics started late, and its development process can be roughly divided into three stages: the first stage, in the early 1960s, in order to meet the needs of national defense construction, researchers in military enterprises conducted a lot of practical research, and then produced a series of technical carriers combining electronic technology with mechanical systems, which laid a stable foundation for the research and development of mechatronics. In the second stage, since 1970s, computer, communication and control technologies have developed rapidly and gradually matured. These external technical foundations have promoted the further development of mechatronics. In the third stage, since the 1990s, the position of civil industry in the national economic system has been gradually strengthened. With the joint research of many scientific research institutions, research units and enterprises, mechatronics technology has developed by leaps and bounds, although there is a big gap with developed countries.
1.3 Features and advantages
With the vigorous rise of emerging science and technology industries, the integration of science and technology has been gradually strengthened, and the traditional energy economy production mode can no longer meet the strategic needs of the current national rise. Therefore, it is not only the need to realize the reform and innovation of technical system and promote the construction of electromechanical integration system, but also has unique advantages.
Application analysis of electromechanical integration technology in coal mine machinery
2. 1 application of mechatronics technology in coal mine safety monitoring system
Coal mine safety production monitoring system is a concentrated expression of electromechanical integration technology, but it started very late in China and gradually began to be applied in coal mines after 1980. There are two main reasons. On the one hand, the safety supervision system that realized electromechanical integration gradually matured and began to be applied in 1980s; on the other hand, the more advanced coal mine monitoring technology abroad greatly promoted and helped the development of safety monitoring technology in China. The application of safety monitoring system has greatly reduced the occurrence of coal mine accidents and undoubtedly played an important role in the safety production of coal mine enterprises.
2.2 application of mechatronics technology in coal mine transportation system
With the gradual maturity of electromechanical integration technology, coal mining enterprises have tried to apply this technology to underground transportation systems, such as belt conveyors. Because of the long transportation distance and high power of belt conveyor, the application of mechatronics can largely eliminate potential safety hazards, and its core technology has been widely developed in practice, which can realize safe transportation with large inclination and long distance. Supporting technologies and key components have also been developed.
2.3 application of mechatronics technology in shearer
Automation of coal mine machinery can not only improve work efficiency, but also greatly reduce potential safety hazards. Therefore, the mechatronics shearer is gradually developed and applied. This type of shearer adopts electric traction, which is more powerful than the traditional hydraulic traction shearer. When the dip angle of coal seam is large and the roof suddenly weighs, the shearer can also brake on its own. At the same time, the mechanical and electrical integration of shearer is simpler, more efficient and more reliable, and it is more and more widely used in coal mine production.
2.4 application of mechatronics technology in hoist
AC/DC digital hoist represents the highest level of electromechanical integration technology of coal mine machinery. In the built-in hoist, the mechanical structure of drive and drum is integrated, which integrates advanced technologies such as power electronics, machinery, automatic control and communication. The all-digital hoist with bus mode not only greatly simplifies the installation of electrical appliances, but also achieves high reliability.

The successful application of mechatronics technology in coal mine machinery has greatly increased the coal output, reduced the mining production cost, increased the economic benefits of coal enterprises, promoted the rapid development of related economic industries and promoted the vigorous development of local economy.
3.3 Improve the safe working environment in coal mines.
A good mining environment is a powerful guarantee for safe production. With the wide application of mechatronics technology, the efficiency of coal mining machinery is greatly improved, and the occurrence of safety hazards is also greatly reduced. The traditional machinery for crushing, assembling, transporting, supporting and handling production links is gradually replaced by modern equipment, which frees miners from dangerous mining work, reduces the probability of dangerous accidents, ensures the personal safety of miners and prevents the occurrence of occupational diseases and industrial injuries.
4 conclusion

It is an organic combination of mechanical equipment, information equipment and software. It mainly relies on science and technology and computer software to realize the informationization and digitalization of mechanical equipment, thus improving the production performance and efficiency of mechanical equipment. The wide application of mechatronics in coal mining machinery can improve the scientific and technological level and production efficiency of coal mining enterprises in China, and then enhance their comprehensive strength.
2 the application significance of mechatronics in coal mine machinery
2. 1 Promote the improvement of production efficiency and benefit of coal mining enterprises.
The application of mechatronics in coal mining machinery meets the requirements of the times of rapid economic development and deepening reform of coal enterprises in China. As far as the production status of coal mining enterprises in China is concerned, although most enterprises have basically realized mechanized production, the overall mechanization level is not high, which seriously restricts the improvement of production efficiency of enterprises. However, due to the in-depth promotion of electromechanical integration technology, the labor efficiency of coal mining enterprises has been significantly improved. In particular, the application of automation technology and micro-processing equipment has improved the individual labor efficiency of workers, and thus improved the overall production efficiency of enterprises. The increase in output has improved the economic profit of enterprises, and at the same time, the income of workers has also increased. The application of mechatronics has greatly improved the level of economic development in China.
2.2 improve coal mine production safety
In recent years, coal mine safety production has become a hot topic in society. As we all know, most traditional coal miners in our country work in dusty, cold and humid environment, and their health and life safety are seriously threatened. The application of mechatronics greatly reduces the labor intensity of workers, improves the working environment, minimizes the possibility of production safety accidents, increases labor safety, and effectively guarantees the life safety of coal mine workers.
3 application example analysis of mechatronics in coal mine machinery
3. 1 application of mechatronics technology in shearer
As one of the most important mechanical equipment in the production process, shearer's working efficiency is directly related to the output of coal mines and the benefits of enterprises. As a typical example of the application of electromechanical integration technology in shearer, electric traction shearer effectively solves the resistance problem in the process of shearer movement. When the shearer slips, the electric traction shearer can use power generation braking, and has a good power-off function at its shaft end to avoid slipping in the production process.
3.2 Application of mechatronics technology in safety production monitoring system
Since 1990s, China has started to study the safety production monitoring system. Through the unremitting efforts of scientists, China finally has its own monitoring system with high technical level, including kj95 system developed by Changzhou Institute of Automation, kj90 system developed by Chongqing Branch of China Coal Research Institute, and so on. In the research and development of these monitoring systems, electromechanical integration technology has been effectively applied.
3.3 Application of mechatronics technology in belt conveyor
Belt conveyor is widely used in China's coal mining enterprises because of its high degree of semi-automation, high mechanical efficiency, long continuous conveying distance and large conveying capacity, and is the main equipment for raw coal transportation. With the in-depth application and continuous development of mechatronics, we can now use a programmable PLC controller with simple design and convenient operation, which does not need complicated interface equipment and input and output equipment. The controller has strong anti-interference ability and can work for a long time even in harsh environment.
4 development trend of mechatronics application in coal mine machinery
4. 1 The application is smarter.
Artificial intelligence technology has not been continuously developed, and the research in the fields of neural network, fuzzy mathematics, psychology and chaotic mechanics has achieved fruitful results, laying a foundation for improving the level of electromechanical integration. Moreover, the demand for coal production in China is constantly expanding, and the demand for intelligent electromechanical products is also increasing. These products are required to have superior logical judgment ability, reasoning ability and even independent decision-making ability. Intelligent electromechanical products have become the demand of the times.
4.2 Application is more humanized
The application of mechanical and electrical products in coal equipment is also to better serve human production activities. Serving people's production and life better is the eternal purpose of the development of mechanical and electrical products. Of course, this also puts forward higher requirements for mechanical and electrical products. China's R&D institutions need to further improve the performance and structure of mechanical and electrical products, and at the same time take care of people's aesthetic needs, starting with the appearance and color of equipment, so that the equipment can be closer to the needs of coal production workers, conform to their work habits and better serve our production and life.
4.3 Application is more environmentally friendly
Since the reform and opening up, China's economy has made rapid progress. At the same time, the ecological environment on which we live has been greatly destroyed, and environmental problems have become a hot issue in society. The development of our society needs more environmental protection technologies and products, which has become the general trend of social development. The application of mechatronics technology in coal industry makes the coal production process more in line with the needs of sustainable development, saves energy and protects the environment. Products are green and environmentally friendly. After the service life of the product is over, it will be decomposed again and then reused. Environmental protection of electromechanical products and its application in coal mine machinery and equipment is the general trend of social development. In short, in order to adapt to the rapid development of economy and the continuous progress of society, the requirements for mechanical and electrical products are also constantly improving. Of course, this can also promote the continuous improvement and development of the application of mechatronics in coal machines. In this way, the coal industry in China can develop continuously, the production efficiency and comprehensive strength can be improved, and then the sustainable development of this industry can be realized.

Model essay on mechatronics: "On the practical teaching of mechatronics in higher vocational colleges" In the industrial production of modern society, new technologies, new processes and new equipment are constantly emerging, and the development of this technology will have a great impact on the social professional structure and demand. Mechatronics major is an important part of the current development of industrial science and technology, and it belongs to the key major of higher vocational education. In the development of mechatronics specialty, we should use the teaching method of combining work with study, attach importance to practical teaching, implement school-enterprise cooperation, and actively improve the practical work skills of higher vocational students.
First, the status quo and reasons of mechatronics practice teaching in higher vocational colleges
In the teaching of mechatronics specialty in higher vocational colleges, a certain proportion of practical teaching content is usually set up. However, due to the influence of many factors, the effectiveness of the corresponding experiment and practice teaching is poor, which leads to the lack of practical ability of students in the internship stage. Students with serious conditions can't work independently for a long time after graduation, their practical ability is seriously insufficient, and their own skills don't meet the market requirements, which also hinders the progress of higher vocational education to a great extent. There are many reasons for the present situation of mechatronics practice teaching in higher vocational colleges. From the perspective of specialized courses, the teaching of mechatronics specialized knowledge has the characteristics of technical integration and interdisciplinary. The actual teaching process is boring and difficult for students to understand, which makes students prone to fear, fails to arouse students' full interest in learning and hinders the cultivation of students' innovative thinking. Especially for those students with poor learning ability and weak grasp of basic knowledge, specialized courses are very difficult.
From the teaching point of view, theoretical teaching is out of touch with practical teaching, and the composition of teachers and hardware facilities are also factors that cause the imperfect development of practical teaching. If the school can't provide enough opportunities for each student to practice independently, it will be difficult for teaching to achieve the expected goal. Judging from the development status of practical teaching in higher vocational colleges, due to various factors, practical teaching lags behind the development of theoretical teaching and cannot meet the requirements of talent training in the new period.
Second, the improvement strategy of practical teaching of mechatronics major in higher vocational colleges
(A) combined with the requirements of industrial development analysis of professional practice ability.
Traditional machinists have gained new development connotation, and the processing and manufacturing methods of products are gradually replaced by new technologies, and the integration of electromechanical technologies is becoming more and more common. Through investigation and comprehensive analysis, it can be found that modern enterprises mainly need to master the knowledge and skills of mechanical and electrical product design and drawing, mechanical and electrical equipment assembly and maintenance, automatic production line operation and debugging. At present, there are three kinds of talents related to the development of electromechanical industry. One is compound management talents, who are required to have both technical ability and management ability, produce products according to the development law of market economy and grasp the development direction of enterprises. Secondly, technical talents with innovative spirit know both technology and management, and can put forward corresponding production improvement plans according to the dynamic trend of the market; Third, intelligent technicians, with rich theoretical knowledge and practical experience, can skillfully operate production equipment and actively carry out technological innovation and maintenance of equipment and processes. For higher vocational colleges, the training goal is mainly to enable graduates to play a role in practical jobs after studying and training in schools and enterprises.
(B) the combination of work and study to form a practical teaching system based on ability.
From the traditional classroom theory teaching to the present laboratory and training base teaching, typical tasks are the main tasks in practical teaching, supplemented by teachers' guidance. In recent years, higher vocational colleges have continuously improved the teaching contents and methods in the teaching reform. The school has been exploring the construction of practical training base and practical teaching system in higher vocational colleges, but there is still a problem that practical teaching is out of touch with social needs, and the positioning of practical teaching of mechatronics is inaccurate. In teaching, simply increase the practice teaching time to improve the teaching mode. The inconsistency between theory and practice also makes students only master skills that cannot be effectively used in the development of actual industries. In the construction of practical teaching system of mechatronics in higher vocational colleges, we should combine the actual development needs of enterprises and industries, fully meet the specific requirements of professional posts, and form a practical teaching system with distinct levels and specific division of labor on the basis of following these principles. According to the teaching rules, knowledge and skills are taught from the simple to the deep. In the practical teaching of mechatronics in higher vocational colleges, we should pay attention to the integration of professional skills training, core skills training and expanding ability training.
(C) School-enterprise linkage, the construction of Industry-University-Research organic combination of practical teaching base.
School-enterprise cooperation teaching mode meets the specific needs of higher vocational education reform, can give full play to the advantages of both schools and enterprises, realize the talent training mode of alternating work and study, and provide quality services for students' internship, training, employment, teachers' re-education and scientific research. Through the teaching mode of school-enterprise cooperation, students can truly understand the role characteristics of professional people and apply their professional knowledge to the actual production environment, which is also an important training method for producing high-skilled talents needed in the front line. Actively building a teaching and training base integrating teaching, training, production and scientific research can promote the progress of personnel training and improve economic benefits. The establishment of off-campus practice teaching base can take the form of national special projects and provincial capital investment to realize mutual benefit and win-win in construction and the stable development of off-campus practice teaching base.
The school adopts technical transformation, equipment renewal and resource integration to build a training base. The construction needs to follow the principle of moderation and sufficiency, and the actual construction activities should be carried out on the basis of full investigation. In the construction and management of campus practice base, we should establish a student-oriented concept, improve our own comprehensive and open characteristics, take improving students' innovative ability as the main task, enhance students' practical ability of electromechanical integration, and make the campus practice base play its due role. On this basis, actively absorb social resources, participate in the construction of off-campus practice base through equity participation, scientifically manage the practice base, and reflect the social service role of higher vocational colleges.
Three. Concluding remarks
Practical teaching in higher vocational colleges is of great significance for students to be familiar with professional knowledge and improve their practical ability. The teaching of mechatronics specialty should also attach importance to the development of practical teaching. Teachers should actively explore teaching methods and cultivate more high-quality skilled talents through effective practical teaching. The improvement of students' practical ability in mechatronics teaching needs the help of practical training to form a practical teaching system of mechatronics in higher vocational education that meets the training objectives of relevant talents in higher vocational education.
