With the development of economy, the mechanical and electrical equipment of coal mine has been rapidly developed and popularized in all aspects, which is directly related to the safety production and economic benefits of the mine. This paper analyzes the problems existing in the electromechanical management of coal mines, and advances some measures for improving the electromechanical management level of coal mines.

1 overview

Mechanical and electrical equipment plays an increasingly important role in coal mine safety production, which runs through every link of the mine production front and is distributed in every corner of the mine, involving a wide range and strong technology. At the same time, due to the complexity of coal mine production conditions and production links, a new topic is put forward for the management of mechanical and electrical equipment. The traditional management method of mechanical and electrical equipment has not adapted to the development of the current situation. Therefore, it is of great significance to strengthen the management of mechanical and electrical equipment, formulate effective management methods and improve management level.

2 status of coal mine mechanical and electrical equipment management

2. 1 There are many hidden dangers in electromechanical equipment. Many mechanical and electrical equipment in coal mines are old, old, miscellaneous and sick, and their safety facilities and protective devices are incomplete, which is far from the requirements of "Coal Mine Safety Regulations". Many coal mines have many old winches, old explosion-proof high-voltage switches, non-flame-retardant tapes that have not been replaced, and old main fans. Among these equipments, the main hoist has single-line braking, the protection of high-voltage switch is incomplete, and the main ventilator can not meet the requirements of negative pressure of mine air volume, which has many hidden dangers. In addition, in recent years, the technical measurement of equipment is not timely, the detection means are backward, it is difficult to find the existing problems, and there are many hidden dangers.

2.2 Coal mines with weak electromechanical technology are unwilling to enter coal mining enterprises because of poor natural conditions and many unsafe factors. In addition, most coal mines think that electromechanical integration is an auxiliary occupation, and they don't pay attention to it, which leads to great fluctuations in the thoughts and emotions of electromechanical personnel. Some technical talents have jumped ship, and talents are extremely scarce. A survey shows that most of the rural coal mines engaged in mechanical and electrical work are migrant workers, and their education level is generally low. Some simple faults of mechanical and electrical equipment can not be eliminated in time, which delays the opportunity of fault treatment and can not play a guiding role in safety production management, let alone the application of computers to participate in modern equipment management. At the same time, the integration of resources and the reduction of mine closures are also the main reasons for the frequent job-hopping of mine technicians.

2.3 Management concept is backward. At present, many coal mine leaders pay insufficient attention to mechanical and electrical equipment, only pay attention to output, and fail to highlight the importance of mechanical and electrical equipment as a modern coal mine production. The mechanical and electrical management department is regarded as an auxiliary production work area, its responsibilities are diluted, its management system is not perfect, and sometimes its implementation is not in place; Mechanical and electrical management personnel have no actual authority and only deal with current production.

2.4 did not give full play to the role of mechanical and electrical management. Although electromechanical management departments are generally set up in coal mines now, most mine electromechanical departments undertake two functions: one is electromechanical management, and the other is electromechanical production. The main energy of managers in the electromechanical department is to cope with production, and the management role has not been fully exerted. At the same time, the electromechanical management institutions in some local coal mines have greatly reduced the number of electromechanical personnel, resulting in a shortage of management personnel, imperfect professional organizations, frequent interruption of management networks, and weakening of the management role of electromechanical functions.

2.5 The intensity and depth of electromechanical supervision is not enough. In the highly professional electromechanical safety supervision, there are few professional supervisors, and the electromechanical transportation system has a long front and a wide range. Safety supervision is generally a random inspection, which is arbitrary and lacks comprehensiveness and initiative. However, the current implementation standards sometimes do not have detailed operation instructions, and some even have certain room for manoeuvre, and there is no very accurate and clear boundary, which will inevitably lead to difficulties in the monitoring process.

3 coal mine mechanical and electrical equipment management measures should be taken

3. 1 increasing investment and optimizing advanced scientific and technological equipment of mechanical and electrical equipment are important guarantees and supports for coal mining enterprises to implement reliable working conditions, improve work efficiency, improve zero defect management level and avoid accidents. First of all, we should increase the investment in equipment funds, recover the relevant funds in full, and keep the novelty coefficient of equipment rising. It is necessary to transform the unreasonable electromechanical system, break through the bottleneck, improve the reliability of the main system equipment and give full play to the production capacity. Attach great importance to the upgrading of mobile equipment in mining areas, eliminate high-consumption, low-efficiency, unreasonable and unsafe process equipment, put an end to the phenomenon of equipment assembly, modification and make-do use, and resolutely stop using the eliminated equipment. Second, follow? Science and technology guarantee, sensitive and reliable? It is required to pursue and vigorously adopt new technologies and equipment to transform traditional equipment. Equipment with uneven protective devices must be fully protected or replaced in accordance with the requirements of "Coal Mine Safety Regulations".

3.2 Efforts to improve the technical quality of workers should be well managed, mechanical and electrical equipment should be well used and repaired, and talents with advanced professional and technical knowledge should be available to give full play to the advantages of advanced equipment. Business technical training is an important basic work of electromechanical management. Trained personnel should not only learn the basic knowledge, but also learn the professional and technical knowledge needed for the current management, use and maintenance of equipment. Training methods can not be limited to one form, but no matter which way is adopted, it is necessary to learn and use consistently, and the teaching materials, teachers and classrooms should be implemented. The depth of teaching materials should be adapted to the culture and professional quality of trainees, and only in this way can good results be achieved.

3.3 Pay attention to the management of mine electromechanical management and * * * members should not only learn the management theory of equipment maintenance, but also learn modern equipment management theory and enterprise management theory. At the same time, it is necessary to fully mobilize the enthusiasm of employees and organize engineering and technical personnel and employees to invest in management activities. And adhere to the way of going out and inviting in, learn from the advanced experience of mine electromechanical management, make up for the shortage of electromechanical management in this unit, find out the gap, make plans, implement them step by step, and gradually improve the level of electromechanical management.

3.4 Improve the electromechanical professional management organization Mine should improve the rules and regulations according to the new quality standards of electromechanical management in coal mines. First, we should establish and improve the corresponding management institutions and improve various management rules and regulations; Second, we must conscientiously implement the safety production policy, strictly implement the production responsibility system, post responsibility system and accident responsibility investigation system, so that everyone is responsible for daily safety production work; Third, comprehensively coordinate the relationship between electromechanical and production, strictly implement the electromechanical management system, make the electromechanical management of the whole mine have rules to follow, regard the electromechanical department as the functional department of the electromechanical management of the whole mine, and give certain rights to let the electromechanical managers give full play to their roles and do a good job in electromechanical management; Fourth, improve the electromechanical management team, rationally allocate professional management personnel, reduce the phenomenon of one person holding several positions, and maintain the stability of the team so as to carry out the work and play a good role.

3.5 Strengthen the on-site management and reasonable maintenance of equipment, and pay special attention to the on-site management of mechanical and electrical equipment. First of all, we should give full play to the dual functions of production and management of mechanical and electrical departments, cooperate with enterprise management and safety supervision departments to do a good job in inspection and assessment, formulate standardized methods for mechanical and electrical management inspection and scoring, strictly implement the cadre attendance system, explosion-proof equipment inspection system and equipment maintenance system, and make on-site management have rules to follow. Secondly, we should strictly supervise, inspect and assess. All production functional departments should give full play to their own management functions, adhere to a standard and a ruler, and strictly control inspection and assessment, so that mechanical and electrical equipment can serve coal production at full capacity and with high efficiency. At the same time, the production unit shall, according to the actual production, formulate the management measures for daily inspection and maintenance of mechanical and electrical equipment and determine the time for daily inspection and maintenance.
