Problems and Countermeasures of Electromechanical Management of Local Coal Mines

China Railway No.: F272 1 Major problems in the local electromechanical management of coal mines The role of electromechanical management functions has not been brought into full play Although the local coal mines are generally equipped with electromechanical management departments, most mine electromechanical divisions assume two functions: First, electromechanical management. Another is electromechanical production. The main focus of mechanical and electrical department management personnel is to cope with production, and management functions have not been fully utilized. Some local coal mine leaders do not pay enough attention to electromechanical management. A large number of compressor and electric power personnel cause insufficient electromechanical management personnel. Electromechanical professional organizations fail to complete, electromechanical management networks are often interrupted, and the role of electromechanical functions is weakened.

Inadequate understanding of electromechanical standardization work Although some mines are equipped with electromechanical standardization management personnel, they are mostly part-time workers. They do not manage or give up management of electrical management, cable management, small-scale electrical appliance management, explosion detection, equipment management, parts management, and grease management. . Some of the electromechanical workers have poor awareness of standardization and have not been able to perform standard posts and standard work. The management of fixed equipment and mobile equipment has not been carried out according to the "Quality Standardization Standard for State-Owned Major Mine Production and Mine Electromechanical Profession Quality Standards". The rate of compliance is low.

The whole process of equipment management, from selection, purchase, acceptance, testing, installation, maintenance, repairs to scrapping, is still not in place. Some mine equipment acceptance and use systems are not enforced strictly. Unqualified products can still be used as human resources. The missing number of the in-use equipment, equipment, and cable signs are incomplete, and accounts, cards, and items do not correspond. Many units still fight the phenomenon of equipment, equipment can not be scheduled to upgrade the wells and maintenance, directly use the surface. The quality of equipment maintenance is not high, some test items have not been done, and some equipments have been used excessively, failing to be disposed of according to regulations. Inadequate equipment upgrade, the new coefficient is far below 0.5.

There are many hidden dangers in the equipment, old, old, miscellaneous and sickly operations, and the safety facilities and protection devices are incomplete. The gap between the requirements of the “Coal Mine Safety Regulations” is relatively large. The lifting system lacks cushioning devices and tray devices, and the electronic control system and braking system are incompletely protected. Wellbore equipment is heavily rusted and fails to be regularly preserved. In some mines, in order to catch up, production and maintenance of the main and auxiliary wells for 2 hours cannot be guaranteed. The actual lifting load of the winch exceeds the designed lifting capacity. Some fixed equipment voltmeters, ammeters, pressure gauges, vacuum gauges, safety valves are not regularly verified. Downhole electrical equipment did not perform electrical tests in accordance with the regulations. Over current protection was set too large. Some used copper, aluminum, and iron wire instead of fuses. Leakage protection, comprehensive protection of coal-fired drills, comprehensive protection of lighting signals, conveyor protection, wind power blocking, gas shut-off, or test and recording are not standardized. The material and process of the downhole local grounding electrode and the connecting wire did not meet the requirements, and the installation was not qualified. Non-flame-retardant cables and conveyor belts are still used downhole. The explosion of electrical equipment is a common occurrence.

Electromechanical technology is weak, technical means are behind some local coal mine technicians are seriously inadequate, technology management can not guide production, and the phenomenon of policing with technology has occurred from time to time. The power supply has no design or design, but it is not standardized. There are no measures for construction or measures, but the measures are not specific. The equipment in the fixed place has not been regularly tested for performance, and the three major protections for downhole power supply have not been set, tested or checked according to technical requirements. Some instruments are aging and incomplete, and testing methods and methods are behind.

Some local coal mine mechanical and electrical management personnel culture is low, professional skills are not high, not systematic learning equipment management theory and business management theory, mechanical and electrical management with experience. Electromechanical workers generally do not receive mechanical and electrical expertise training, lack of theoretical knowledge, lack of practical experience, illegal operations often occur. The equipment failure is more devastating. Gas and coal dust explosions caused by electrical explosions occur almost every year. The “two-vote-three-system” electricity management system does not insist on strict operation and live work.

Electromechanical training goes through the field and fails to achieve the purpose of training. Although local electromechanical training for the coal mines is carried out year after year, due to weak pertinence, abstract theory is explained, employees cannot understand, practice methods are not taught, and workers cannot be applied in practice. . The theory can not be linked to reality, resulting in poor enthusiasm for learning of employees, and mechanical and electrical training to go through the field. Failure to achieve the "I want to learn" to "I want to learn" change, training can not achieve the purpose.

Local coal mines are subject to capital constraints, and there is a general shortage of equipment and a limited number of spare parts. Due to the complex geological conditions and limited resources, frequent moving and moving surfaces have caused the installation, maintenance and maintenance of mechanical and electrical equipment to increase. The electromechanical workers have often been delayed due to overtime, and the treatment has been relatively low. Some electromechanical technicians have successfully switched jobs. Production is in a passive state.

2 Ways to improve local coal mines' mechanical and electrical management. Pay attention to management and improve the level of mechanical and electrical management. Pay attention to mechanical and electrical management. First, mine leaders pay attention to mechanical and electrical management. This is the key to strengthening mechanical and electrical management. Electromechanical management personnel should often report their mechanical and electrical work to the mine leaders and make more suggestions for their work to obtain leadership support.

At present, the mechanical and electrical management of local coal mines is basically in the equipment maintenance management stage. In fact, the electromechanical management of mines should make the life of the equipment a system, manage the entire process of equipment operation, pursue the optimization of equipment life cycle cost, and conduct comprehensive management from the aspects of technology, economy, and organization. Therefore, the mine mechanical and electrical management personnel must not only learn the theory of equipment maintenance management, but also learn modern equipment management principles and insist on going out, please come in the way, learn the experience of advanced mine mechanical and electrical management, make up for the lack of mechanical and electrical management of the unit, find Gap the gap, make plans, step by step, and gradually improve the level of mechanical and electrical management.

The establishment of an electromechanical management institution due to mine conditions, the granting of authority, and the unified management of the settings, staffing, organizational forms, and system structures of the mine electromechanical management institutions must be adapted to local conditions and vary from mine to mine, and cannot be a model, but should be relatively stable. At present, the establishment of an electromechanical management structure system parallel to the production system is the development direction. For the mines with large wells and relatively solid foundation work, an electromechanical management department is set up to take charge of the whole mine electromechanical technology, equipment management, and electromechanical work scheduling, and to the entire mine. Electromechanical work implements unified management. Wells with small wells, simple production processes, and low equipment possessions can be combined into mechanical and electrical management areas and electrical and electrotechnical areas, which will help reduce people's effectiveness.

No matter which form is adopted, the mine electromechanical management system must grant the authority of the electromechanical department and implement unified management. The general electromechanical department must have the following powers, namely: to formulate the rights of electromechanical management rules and regulations; to draft and deploy electromechanical work plan rights; to allocate equipment and accessories rights; to stop illegal operation rights; to chase electromechanical accident rights; Mobilize the right to work supervision.

Strengthen the management of electromechanical standardization, establish and improve the standardization management organization, improve the quality standardization awareness of all electromechanical personnel, and carry out electromechanical work according to the standardization requirements.

Electromechanical standardization is the basis for ensuring the mechanical and electrical safety production of mines. Local coal mines should gradually improve the work of electromechanical standardization, establish a standardization leading group, and formulate standardized construction goals, concrete measures, and completion time. The implementation of "three grasps", that is to grasp the quality of the surface upgrade, online grasping the header surface, machine path, room, point to grasp the weak links. The establishment of electromechanical standardization rewards and penalties system, the development of mechanical and electrical standardization competitions, establishment of a standardized model electromechanical zone team, computer room bedroom, machine path, and promote the full implementation of electromechanical standardization work.

The basic task of equipment management for well-integrated equipment management is to master the equipment dynamics, establish and maintain equipment files, handle equipment transfer procedures, master the equipment technical performance status, and prepare equipment purchase, upgrade, renovation, repair, and spare parts plans. Master the use of major repair funds and implement the entire process of equipment management. Each mine shall establish a comprehensive equipment management system, improve the comprehensive equipment management system, complete equipment management personnel, implement process management, and do a solid job of comprehensive equipment management to ensure that equipment management is institutionalized, normalized, and standardized.

Regulations and rules are the criteria for the operation of electromechanical businesses. They are disciplinary guarantees for good mechanical and electrical work and should be established. At present, the unfavorable implementation of the rules and regulations is a prominent issue, especially the implementation of systems such as operations, maintenance, comprehensive balance, quality inspection, and site management. The main working object of the electromechanical management of mines is equipment. The implementation of rules and regulations must also include the management, use, and repair of equipment as the main work content. At present, the rules and regulations that are urgently needed to be implemented are: the responsibility system for mechanical and electrical management personnel; the operational procedures for equipment use; the system for maintenance, inspection, maintenance, and quality inspection of equipment; the management of mechanical and electrical accidents, on-site equipment management, technical management, comprehensive balance, economic accounting for teams and groups, etc. system.

Implementing program management and strengthening comprehensive balance plan management are the core of mechanical and electrical management and the basis for organizing electromechanical business activities. The preparation of an electromechanical work plan should generally be based on the technical status of electromechanical equipment, mine production plans, corporate financial and material resources, electromechanical construction technology, technical conditions, and the opinions and requirements of superior electromechanical authorities.

The timely and effective coordination of balance is an indispensable means for the smooth implementation of the plan. To do a good job of coordination and balance, we must first have a relatively well-balanced and coordinated agency. In addition to the current local coal mines equipped with a certain number of management personnel responsible for the daily business work of the balance, the larger mines should set up an electromechanical control room, equipped with a dispatcher, responsible for the scheduling of electromechanical work. Small mines can take the method of electromechanical management personnel and technicians on duty in turn and perform the duties of electromechanical dispatchers.

The second is to establish and improve a comprehensive balance of work systems, such as electromechanical management (technical) personnel on shift duty, electromechanical work production regular meeting, workshop team daily operation planning system, mining and transportation mechanical and electrical district chief, maintenance team leader meeting system.

Once again, it regularly organizes and analyzes aspects of mechanical and electrical equipment safety, quality, maintenance, dynamics, power and secondary distribution of units. The coordination of electromechanical work must also be changed according to the seasonal focus.

The implementation of the technical personnel responsibility system and the reinforcement of technical management technical personnel are the main subjects of technical management. Implementing the responsibility system for technicians, responsibilities, powers, and responsibilities of professional teams and groups is an effective way to give full play to the role of technical personnel and strengthen technical management. It is convenient for technical personnel to solve technical problems in production activities and do a good job of technical management.

In order to improve the quality of work in electromechanical technology management, the approval system for technical documents must be rigorously and hierarchically responsible and checked at all levels. Pay attention to the accumulation of technical data and scientific and technological information retrieval, do a good job in the management of drawings and data files. Equipment operations, inspections, maintenance, inspections, accidents, and other records must be well-documented, properly kept, and archived. Equipment technical performance measurement reports, inspection, evaluation, summary, work plans, reports, reports, and quotas of mechanical and electrical work must also be archived for future use.

Mine electromechanical systems are more complex and must focus on their work.

The current electromechanical management should highlight the following three aspects: 1 Safety and reliability. The important equipment and electrical equipment that endanger the safe production of mines must be renewed and transformed in a timely manner. For those equipment that temporarily cannot meet the requirements and standards of the “Coal Mine Safety Regulations”, Instalments were made in batches to gradually increase the safety and reliability of the equipment. 2 Downhole power supply and upgrade transportation 2 systems, downhole power supply is the power system for mining first-line equipment, the environment is complex and changeable, the structure varies from machine to machine, focus on the on-site management of mobile equipment, improve safety protection devices, eliminate electrical equipment loss burst. Lifting transportation is the throat of the mine. It has a wide work surface and a large quantity. It is necessary to further improve various protection devices for the transportation system, and to maintain daily mandatory maintenance for 2 hours. The belt conveyor must use integrated protection of the conveyor.

The three links focus on three links: operation, maintenance, and repair. Failure to comply will result in an accident. Failure to inspect and repair will not reveal hidden dangers. Failure to repair and repair aging will not be compensated. In order to do a good job in these three aspects, the production order of the mine will basically remain normal.

Efforts should be made to improve the technical quality of the employees' business. To properly manage, use, and repair mechanical and electrical equipment, talents with advanced professional and technical knowledge must be available to take advantage of advanced equipment. Business technical training is an important basic work of electromechanical management. Trained personnel need not only to learn the basic knowledge, but also to learn the professional technical knowledge needed to manage, use and repair the equipment. Training methods and methods should not be limited to one form. However, no matter which method or method is adopted, it must be consistent in learning and use, and teaching materials, teachers, and classrooms must be implemented.

The depth of teaching materials should be adapted to the cultural and business quality of the trainees. Only in this way can good results be achieved. At the same time, it establishes incentive mechanisms, such as the assessment of technical titles (including workers' evaluation technicians), and the combination of economic capabilities of enterprises to improve the economic treatment of the technology.

Clear guiding ideology, implementation of objective management, and careful evaluation of the quality of mechanical and electrical work The guiding ideology of mine mechanical and electrical work is generally to mention the quality of equipment maintenance, reduce electrical and mechanical accidents, ensure the normal production order of mines, and constantly raise the level of electrical and mechanical management, so that Mines get the best economic benefits. Each mine must formulate specific guidelines based on the actual conditions of work progress.

The overall goal of electromechanical management of mines is to make equipment safe and economical and reasonable to operate, and to pursue the optimization of equipment life cycle costs, so that the overall efficiency of the equipment is the most flawed. Each mine must formulate specific goals in accordance with the quality of equipment maintenance and management personnel's business technical quality, technical conditions, and the degree of leadership of the importance of mechanical and electrical work, and gradually achieve the most desirable goals.

The current assessment of mechanical and electrical management work quality indicators generally have equipment integrity rate, equipment repair rate, electromechanical accident rate, equipment usage rate, equipment load rate, electricity consumption cost rate, equipment cost rate, spare parts cost rate, maintenance cost Rate, spare parts reserve cost rate, maintenance personnel efficiency, etc. The electromechanical management departments must organize strict evaluations during the tenth, the month, the quarter, and the year, and reward excellent and punished, and promote electromechanical management.

3 Conclusion In conclusion, the current local coal mine mechanical and electrical management, must start from the basic work, to improve the safety and reliability of mine mechanical and electrical equipment as the center, in order to take economic leverage as a means to do a good job mechanical and electrical management work, ensure the safety of mine mechanical and electrical systems Reliable and efficient.
