Middle figure No.: F272 1 Main problems in electromechanical management of local coal mines The role of electromechanical management functions is not fully exerted Although most local coal mines have set up electromechanical management departments, most of the mine electromechanical departments have two functions: First, electromechanical management The other is electromechanical production. The main focus of the mechanical and electrical management staff is to cope with production, and the management role has not been fully utilized. Some local coal mine leaders pay insufficient attention to electromechanical management. A large number of compressor electricians have caused insufficient electromechanical management personnel. The electromechanical professional organizations have not been perfected. The electromechanical management network has been interrupted frequently, and the functions of electromechanical functions have been weakened.
Insufficient understanding of electromechanical standardization work Although some mines have electromechanical standardization management personnel, they are mostly part-time, and management of electrical management, cable management, small electrical appliances management, explosion-proof inspection, equipment management, parts management, and grease management are not in place or abandoned. . Some of the electromechanical workers have poor standardization awareness, failing to achieve the standard post and standard work. The management of fixed equipment and mobile equipment has not been carried out according to the "Standards for the Quality of Mechanical and Electrical Professionals in the Production of Mines in State-owned Key Coal Mines". The head rate is low.
The whole process management of equipment from selection, purchase, acceptance, testing, installation, maintenance, repair to scrapping is not in place at some points. Some mining equipment acceptance and use systems are not implemented strictly, and unqualified products can still be used and used. The number of equipment and equipment is missing, the equipment and cable signs are incomplete, and the accounts, cards, and objects do not correspond. The phenomenon of many units assembling equipment still exists, the equipment can not be repaired and repaired according to the plan, and the surface is used directly. The quality of equipment maintenance is not high, some test items have not been done, some equipment has been used overdue, and it has not been disposed of as required. Insufficient equipment update, the new degree coefficient is far below 0.5.
There are many hidden dangers in the equipment: old, old, miscellaneous, sick, and safety facilities and protective devices are incomplete. There is a big gap between the requirements of the “Safety Regulations for Coal Minesâ€. The lifting system lacks a buffer device and a canning device, and the electronic control system and the braking system are incompletely protected. The wellbore equipment is seriously corroded and cannot be regularly preserved. In order to catch up with production, some mines cannot guarantee the 2 h shutdown and maintenance time of the main and auxiliary wells. The actual lifting load of the winch exceeds the design lifting capacity. Some fixed equipment voltmeters, ammeters, pressure gauges, vacuum gauges, and safety valves are not regularly calibrated as specified. The underground electrical equipment did not perform electrical tests according to the regulations. The overcurrent protection was too large, and some used copper, aluminum and iron wires instead of fuses. Leakage protection, coal electric drill comprehensive protection, comprehensive protection of lighting signals, conveyor protection, wind power lockout, gas electric lockout, or test and record are not standardized. The material and process of the local grounding electrode and connection of the underground did not meet the requirements, and the installation was unqualified. Non-flame-retardant cables and conveyor belts are still used underground. The explosion of electrical equipment is not uncommon.
The electromechanical technology is weak, and the technical means are backward. Some local mine technicians are seriously inadequate. Technical management cannot guide production. The phenomenon of political technology has occurred from time to time. The power supply has no design or is designed but not standardized. There are no measures or measures in the construction, but the measures are not specific. The equipment in the fixed place fails to perform the performance test regularly. The three major protections of the underground power supply fail to be set, tested and inspected according to the technical requirements. Some instruments are aging and incomplete, and the testing methods and methods are backward.
Some local coal mine electromechanical management personnel have low culture, low professional and technical level, no systematic learning equipment management theory and enterprise management theory, and electromechanical management based on experience. Mechanical and electrical workers generally do not receive mechanical and electrical expertise training, lack of theoretical knowledge, lack of practical experience, and frequent violations. Equipment failures are relatively embarrassing, and gas and coal dust explosions caused by electrical explosions occur almost every year. Electricity management "two tickets and three systems" insisted on lax, live operation, when the power is stopped at about the time.
Electromechanical training went through the field and could not achieve the purpose of training. Although the electromechanical training work of local coal mines was carried out year after year, due to the lack of pertinence, the abstract theory explained, the employees could not understand, the practical operation methods were not specific, and the employees could not apply in practice. . The theory cannot be linked to reality, resulting in low enthusiasm for employees to learn, and electromechanical training has gone through the game. The 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 widespread shortage of equipment and limited spare parts. Due to the complicated geological conditions, limited resources, frequent moving parts, resulting in increased installation, maintenance and maintenance of mechanical and electrical equipment, electromechanical workers often work overtime, and the treatment is relatively low. Some embarrassing electromechanical technicians have quit, electromechanical safety. Production is in a passive state.
2 Ways to improve the electromechanical management of local coal mines Pay attention to management, improve the level of electromechanical management and pay attention to electromechanical management. First, the mine leaders attach importance to electromechanical management, which is the key to strengthening electromechanical management. Electromechanical management personnel should regularly report to the mine leaders on mechanical and electrical work, and make more suggestions for work to obtain leadership support.
At present, the mechanical and electrical management of local coal mines is basically in the stage of equipment maintenance and management. In fact, the mine electromechanical management should make the life of the equipment a system, implement the whole process of equipment operation management, pursue the optimization of equipment life cycle cost, and comprehensively manage from the aspects of technology, economy and organization. Therefore, the mine electromechanical management personnel must not only learn the management theory of equipment maintenance, but also learn the modern equipment management and insist on going out, please come in, learn the experience of advanced mine electromechanical management, make up for the shortcomings of the electromechanical management of the unit, find Out of the gap, formulate plans, implement step by step, and gradually improve the level of electromechanical management.
Due to the establishment of an electromechanical management institution due to the mine system, the authority and authority for the unified management of the mine electromechanical management organization shall be tailored to the local conditions and different from the mine. It shall not be a mode, but it shall be relatively stable. At present, the establishment of an electromechanical management structure system juxtaposed with the production system is the development direction. For mines with large well types and relatively solid foundation work, an electromechanical management department is set up, which is responsible for the electromechanical technology, equipment management, and electromechanical work scheduling of the whole mine. The electromechanical work is managed in a unified manner. Mines with small well types, simple production links and low equipment ownership, electromechanical management and machine and electrician areas can be combined into one, which is conducive to reducing people's efficiency.
No matter which form the mine electromechanical management system adopts, it must grant the authority of the electromechanical department and implement unified management. The general electromechanical department must have the following functions, namely: to formulate the right to operate the rules and regulations of electromechanical management; to formulate the right to deploy electromechanical work plans; to assign equipment accessories; to stop illegal operation rights; to chase mechanical and electrical accident rights; to review and evaluate the right to award and punishment; Transfer the supervision of work.
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 safe and mechanical production of mines. Local coal mines should gradually improve the electromechanical standardization work, establish a standardization leading group, and formulate the goals, specific measures and completion time of standardization construction. Implement the "three catches", that is, to upgrade the quality of the surface, grasp the head surface, the machine path, the machine room online, and focus on the weak links. Establish an electromechanical standardization reward and punishment system, carry out electromechanical standardization competition activities, establish a standardized model electromechanical zone team, machine room diverticulum, and machine path, and promote the comprehensive development of electromechanical standardization work.
Do a solid job in equipment management The basic task of equipment management is to master equipment dynamics, establish and maintain equipment files, handle equipment transfer and transfer procedures, master equipment technical performance status, and prepare equipment purchase, renewal, transformation, repair, and parts planning. Master the use of overhaul funds and implement the entire process of equipment management. Each mine should establish an integrated equipment management system, improve the equipment comprehensive management system, equip the equipment management personnel, implement the process management, and do a good job in the comprehensive management of equipment to ensure the institutionalization, normalization and standardization of equipment management.
The rules and regulations are the norms of electromechanical business activities, and they are the discipline guarantee for mechanical and electrical work, and should be established and improved. At present, the implementation of rules and regulations is an outstanding problem, especially in the implementation of systems such as operation, maintenance, comprehensive balance, quality acceptance, and on-site management. The main working object of mine electromechanical management is equipment. The implementation of rules and regulations must also be managed, used well and repaired equipment as the main work content. The current rules and regulations that are urgently needed to be implemented are: electromechanical management personnel responsibility system; equipment operation and operation rules; equipment maintenance, inspection, maintenance, quality inspection and acceptance system; mechanical and electrical accident management, equipment site management, technical management, comprehensive balance, team economic accounting, etc. system.
Implementing plan management and strengthening comprehensive balance plan management is the core of electromechanical management and the basis for organizing electromechanical business activities. The preparation of electromechanical work plans should generally be based on the technical status of electromechanical equipment, mine production plans, corporate financial and material resources, electromechanical construction technical strength, technical conditions, and opinions and requirements of superior electromechanical authorities.
Timely and forceful coordination of the balance is an indispensable means of smooth implementation of the plan. To do a good job of coordination and balance, we must first have a more effective coordination and coordination mechanism. At present, local coal mines are equipped with a certain number of management personnel responsible for the balance of daily business work. Larger mines should set up an electromechanical dispatching room with dispatchers to be responsible for the scheduling balance of electromechanical work. Small-scale mines can take the responsibility of electromechanical management personnel and technicians to take turns, and act as an electromechanical dispatcher.
The second is to establish and improve a comprehensive balanced work system, such as the mechanical and electrical management (technical) personnel on-duty system, mechanical and electrical work production regular meeting, workshop team daily operation planning system, mining and mining machinery and equipment chief, maintenance team leader meeting system.
Once again, it regularly organizes and analyzes the safety, quality, maintenance, dynamics, power and secondary distribution of electrical and mechanical equipment. The coordination of electromechanical work will also vary according to the seasonal focus.
Implementing the technical personnel responsibility system and strengthening the technical management technical personnel are the main subjects of technical management. Implementing the technical personnel responsibility system, responsibilities, powers and professional team responsibilities are the effective way to give full play to the role of technical personnel and strengthen technical management, so that technical personnel can solve technical problems in production activities and do a good job in technical management.
In order to improve the quality of the work of electromechanical technology management, it is necessary to strictly review the approval system of technical documents, and to be responsible for the classification and management. Attach importance to the accumulation of technical data and scientific and technological information retrieval work, do a good job in the management of drawings and technical files 7:. The operation, inspection, maintenance, overhaul, accidents and other records of the equipment must be analyzed and organized, properly kept, and archived. Equipment technical performance measurement report, inspection, evaluation, summary, work plan, report, report, and quota indicators of electromechanical work must also be archived.
The mine electromechanical system is more complicated and must focus on the work.
The current electromechanical management should highlight the three key points: 1 safety and reliability, important equipment and electrical equipment that endanger the safe production of mines must be updated and modified in a timely manner. For equipment that does not meet the requirements and standards of the Coal Mine Safety Regulations, The rectification will be carried out in stages and in batches to gradually improve the safety and reliability of the equipment. 2Two systems for underground power supply and lifting transportation. Underground power supply is the power system for mining first-line equipment. The environment is complex and varied. The structure varies from machine to machine. Focus on the on-site management of mobile equipment, improve safety protection devices, and prevent electrical equipment loss. burst. The transportation is the throat of the mine. The working surface is wide and the volume is large. It is necessary to further improve the various protection devices of the transportation system, and insist on the mandatory maintenance for 2 hours every day. The belt conveyor must use the comprehensive protection of the conveyor.
The focus of the 3 links is the operation, maintenance and repair. If the operation is not followed, the accident will occur. If the inspection is not carried out, no hidden dangers can be found. Grasping these three aspects, the production sequence of the mine will remain basically normal.
Efforts to improve the technical quality of employees must be managed, used well, and repaired mechanical and electrical equipment. Talents with advanced professional and technical knowledge must be able to take advantage of advanced equipment. Business technology training is an important foundation work of electromechanical management. Trained personnel must learn the basics and learn the technical expertise needed to manage, use and repair equipment. Training methods and methods should not be restricted to one form, but no matter which method is adopted, it must be consistent in learning, and the teaching materials, teachers, and classrooms should be implemented.
The depth of the textbook should be adapted to the cultural and business quality of the training object. Only in this way can we achieve good results. At the same time, establish incentive mechanisms, such as assessing technical titles (including workers' assessment technicians), and combining the economic capabilities of enterprises to improve the economic treatment of technology.
Clear guiding ideology, implementing target management, and carefully evaluating the quality of electromechanical work. The guiding ideology of mine electromechanical work is to improve the quality of equipment maintenance, reduce mechanical and electrical accidents, ensure the normal production order of mines, and constantly improve the level of electromechanical management. The mine gets the best economic benefits. Each mine must formulate specific guiding ideology according to the actual situation of work progress.
The overall goal of mine electromechanical management is to make the equipment safe, economic and reasonable, and to optimize the life cycle cost of the equipment, so that the overall efficiency of the equipment is the most bleak. Each mine shall, according to the quality of equipment maintenance and the technical and technical quality of the management personnel, technical conditions, and the degree to which the leadership attaches importance to electromechanical work, formulate specific goals for progress and gradually achieve the ultimate goal.
The current indicators for assessing the quality of electromechanical management generally include equipment integrity rate, equipment repair rate, mechanical and electrical accident rate, equipment utilization rate, equipment load rate, power consumption cost rate, equipment cost rate, accessory cost rate, and maintenance cost. Rate, spare parts reserve rate, maintenance staff efficiency, etc. The mechanical and electrical management department shall organize strict evaluations in the tenth, the month, the season and the year, and reward and reward the fine and promote the electromechanical management.
3 Conclusion In summary, the current mechanical and electrical management of local coal mines must start from the basic work, to improve the safety and reliability of mine electrical and mechanical equipment as the center, to use economic leverage as a means to do a good job in mechanical and electrical management to ensure the safety of mine electromechanical systems. Reliable and efficient.
