China's coal industry has gone through several stages of development from the early manual labor to the current high-tech coal mining technology. Due to the progress of China's coal industry mining technology, it has played a very good role in promoting other undertakings in China. In today's historical development, we require higher requirements for the coal industry, and the technology of the coal industry has also undergone many major transitions. As an important energy source, coal must significantly increase its output and labor productivity, apply modern scientific and technological achievements, and strive to improve the level of comprehensive mechanization and automation. As one of the important connotations of coal industry electromechanical integrated technology Especially outstanding.
1 Development status of electromechanical integration technology in China's coal enterprises
The application of coal mine electromechanical integration technology With the continuous introduction and partial localization of domestic imported mining machinery, the level of coal mine electromechanical integration is constantly rising, and has achieved certain results. With the continuous development of coal mine production to a high level, the requirements for control level and scale are also getting higher and higher, thus accelerating the development and progress of electromechanical integration technology. However, the automation level of China's coal system is still a certain distance from that of developed countries.
1.1 Integration and routinization of coal mine equipment
At present, advanced mechatronics technology has been applied to the mechanical equipment of the coal mine, but no systematic trend has been formed. The application of state-owned new large and medium-sized coal mines is better, while the application of traditional small and medium-sized coal mines is worse. In the production of coal mining machinery, China's coal machinery enterprises need to transform from scattered technical means to systematic supporting aspects. There is still a big gap between the electromechanical integration products and the international counterparts in the programmed application, especially in the mechanical equipment of coal enterprises. Proceduralization is the necessity of the development of mechatronics in coal mining enterprises.
1.2 Underground intelligent equipment in China's coal mines
Underground robot and intelligent operation equipment are complete and independent equipment provided by coal mine electromechanical integration technology, which is a great contribution to the coal mining industry. Large scale mining equipment in China, especially underground electromechanical equipment, has a serious impact on the working reliability and safe production of machines due to the low level of equipment capacity, reliability and detection intelligent control. In order to completely change this backward situation, the goal of coal mining machinery is to realize the electromechanical integration of coal mining, tunneling, transportation and support equipment.
1.3 Mine safety production monitoring system
The mine safety production monitoring system is one of the technologies that can best reflect the coal mine electromechanical integration. At present, most coal mines in China have installed monitoring systems, greatly improving the safety of the underground. Although the domestic safety monitoring systems can basically meet the requirements of coal mines, due to the shortage of the corresponding supporting sensors, such as few types, short life, heavy maintenance workload, etc., the reliability of many monitoring systems is not high, and the system utilization rate is low.
1.4 Mine transportation lifting equipment
Belt conveyor can not only meet the requirements of long distance continuous conveying, but also has the characteristics of large conveying capacity, reliable operation, high efficiency and automation. It has become the main transport device in coal mines in China. Therefore, it has become the research focus of mechatronics technology today. China has produced many kinds and types of belt conveyors.
2. Development and innovation of electromechanical integration technology in China's coal enterprises
The development of the coal industry has gone through hardships. The reason for such brilliant achievements in modernization is inseparable from the progress of coal electromechanical technology. With the acceleration of the modernization process of coal mines and the rapid development of safety technology, various underground monitoring and monitoring systems are gradually increasing. If these monitoring and monitoring systems are in an independent state, various systems are self-contained, and information cannot be exchanged, it is bound to cause repeated investment in communication lines, repeated construction, increased system maintenance, poor overall reliability, maintenance The wide application of computer control technology and network technology in coal mines has solved these problems well.
Now, computer control and network can cover the underground scene of coal mine, single equipment and single data measurement point. Any networked computer on the ground can directly consult relevant information or send relevant information to the underground when authorized. Managers at all levels can achieve unified scheduling in workshops, district teams, mines, enterprises and even around the world Control and management. These networks and control systems are changing the technology and industrial structure of the traditional coal industry, bringing revolutionary changes to the optimized dispatching and scientific management of modern mines. The main development trend of coal mine electromechanical technology and equipment should be: tracking the scientific and technological frontier of the industry, developing core technologies with independent intellectual property rights dominated by coal mining technology and supporting equipment, and occupying the technical commanding heights with its high adaptability, large-scale, high-power, remote control and automation; The development of working condition and health monitoring of mine equipment based on microprocessors and microcomputers, as well as the application of microprocessors, computers and expert systems, will gradually become an important symbol of the development of modern coal mine electromechanical technology.
2.1 Strengthen the management of electromechanical integration
To strengthen the management of mechatronics, we should first pay attention to the technical management of equipment; Secondly, we should pay attention to the on-site management of electromechanical equipment and give full play to the dual functions of electromechanical and safety production management; Thirdly, do a good job in the management of electromechanical equipment, dare to innovate boldly, and carry out technical transformation of equipment. As far as the equipment is concerned, we should carry out reasonable technical transformation on the equipment according to the actual production and in combination with the problems existing in the repair and maintenance, so as to make it for our own use and give better play to the efficiency of the equipment.
2.2 Mechatronic intelligent control of coal mining enterprises
Mining operations are carried out in an unstructured environment, which is not only difficult to model, but also has strong uncertainty. The prediction and control of mine safety and disasters have greater uncertainty. Therefore, the development and application of intelligent control in the coal field has important practical significance and huge potential.
2.3 Power electronics and electric drive automation of electromechanical integration in coal mining enterprises
In recent years, our country has carried out the application research work of AC speed regulation and digital DC speed regulation system in the electric drive and automation of coal mines, and has achieved good results progress At the same time, foreign advanced mine hoists and shearers with modern AC speed regulation are also introduced. Obviously, this will play a positive role in improving the level of electrical transmission and automation in China's coal mines and striving to catch up with the world's advanced level as soon as possible.
2.4 Strive to strengthen mine quality standardization management
2.4.1 The mine must establish a practical and feasible equipment management system, explosion-proof equipment entry inspection system, equipment charter system, equipment regular inspection system, regular test system of various safety devices and blackout maintenance tag system.
2.4.2 Carefully implement the principle of combining equipment use and maintenance. The person who uses, manages and maintains the equipment shall be directly responsible for the safety and implement the special responsibility system, and the package mechanism shall be implemented for the main equipment. For equipment produced by multi shift system, operators must implement the equipment shift system, and large equipment has operation records.
3 Conclusion
Mechatronics is the crystallization of many scientific and technological developments and the inevitable requirement for the development of social productivity to a certain stage. It has not only greatly improved the production level and capacity of coal mines, but also created huge economic and social benefits. Only by developing more electromechanical products with independent intellectual property rights in a new way and in a shorter time, can coal mine production continue to develop to a high level, thus further accelerating the development and progress of electromechanical technology. Therefore, the coal mine with new electromechanical integration technology and equipment can enable enterprises to obtain more significant technical, economic and social benefits, which is also a process of promoting the continuous development of coal mining enterprises.
