1. Production management: refers to a series of management activities carried out on the production process activities, that is, a series of planning, organization and control work on the production process activities. 2. Balanced production: It is an important criterion for measuring the production management level of an enterprise. The balanced production of mining enterprises means that the output can be stable within ±5% of the daily planned level, and the actual output can be stabilized. Balanced production is achieved within ±5% of the monthly average daily production. 3. Regular circulation operation: When the working face is returned within 24 hours, all the processes and workloads specified in the cycle chart in the operation procedure are completed in accordance with the quality and safety, and the specified number of cycles is completed repeatedly. Regular cycle criteria: â‘ mining Mine Wide informal mining face organize regular cycle of operation, which meet the required standards in the face each accounted for more than 70%; â‘¡ comprehensive national plan to complete production of the footage, coal quality, efficiency and so on eight indicators; 3 The engineering quality of the mining face is qualified, the mechanical and electrical equipment maintenance meets the quality requirements, and the upper and lower environmental sanitation are well done; 4. Compliance with national technical policies and safety regulations, circulation chart around the mining face, preparation and implementation of mine transportation, electromechanical maintenance, and mining Continue the chart to establish a normal production order; 5 to achieve safe production, eliminate major malignant accidents and major accidents. 4. Coal mine labor quota: refers to coal enterprises under the certain production technology conditions, make full use of machinery and equipment, organize labor reasonably, and on the basis of effective use of advanced technology, to produce a certain amount of coal or to complete a certain work. The number of pre-specified labor consumption standards. Characteristics: basic, rational, extensive, and advanced. 5, equipment life points: material, economic, technical life. Technical life: Due to the development of science and technology, new equipment with more advanced technology and more economical rationality has emerged, so that the original equipment will be scrapped before the end of the material life or economic life. The technology is backward and eliminated, and the time elapsed is called the technical life of the equipment. Economic life: At the end of the material life of the equipment, due to the serious physical wear and tear, this equipment can continue to be used technically, but it may not be economically economical. It must rely on high maintenance fees to maintain its operation. Determining the economically reasonable period of use, usually the minimum average usage fee is used to determine this period. The life of the equipment determined by the usage fee is called the economic life. 6. Mining organization: Under the existing conditions of the mining face, according to the objective requirements of the development of mining work, make full use of manpower and material resources to make reasonable arrangements and cooperation on the production process of the working face in terms of time, space and equipment capabilities. And make it consistent in the production process, in order to achieve the specified output and footage, and to achieve the best results. 7. Mining relationship: The relationship between coal mining and excavation is one of the basic contradictions unique to mine production and construction. Excavation is for mining, coal mining must be excavated, and excavation work must be arranged according to the demand of coal mining. First, the development of tunneling and mining must maintain a correct proportional relationship. 8. Scope and content of scheduling statistics: 1 Scope: Since the basic tasks of production scheduling are “grasping production, grasping safety, and grasping production preparationâ€, the scheduling statistics must be carried out around these three aspects, and cooperate with relevant departments. Statistics on the completion of economic and technical indicators, key projects, “three violationsâ€, quality compliance, production costs, and profits. 2 Contents: Recent statistics, including statistics on the completion of production tasks in class, day and day, statistics on the attendance of mining workers, standardization of quality standards in mining face, balanced productivity statistics, accident statistical analysis, production costs and profit and loss statistics. Long-term statistics, including monthly, seasonal, annual production statistics, technical and economic indicators statistics, mine quality standardization statistics, accident statistics, etc. 9. The concept and connotation of total quality management: 1 concept, the so-called total quality management, is the joint efforts of all employees and relevant departments of the enterprise, combining professional technology, management, mathematical statistics and ideological education to establish research and design of products, The quality assurance system for the whole process of production, after-sales service, etc., so as to produce the products that the users are satisfied with the most economical means. 2 Connotation, which embodies the comprehensiveness of quality management, not only the management of all quality, the management of all employees, the management of the whole process, but also the comprehensive management of multiple methods, that is, the management of the whole, which shows that the purpose of quality management is economy. The development, development and sales of products that satisfy customers are indicative of the premise of quality management based on the solid sense of responsibility, responsibility and enthusiasm of all employees.
10. Mine production scheduling system: (1) cadre duty system; (2) dispatching conference system 1 class before meeting 2 production scheduling meeting 3 production balance meeting 4 accident analysis meeting; (3) step-by-step reporting system; (4) dispatching room handover system; (5) scheduling data storage system. 11. The role of labor quota: 1 Labor quota is the scientific basis for coal enterprises to compile plans and organize production; 2 Labor quota is an important basis for enterprises to prepare staff and organize labor reasonably; 3 Labor quota is for enterprises to implement economic responsibility system, and implement Labor distribution provides conditions; 4 labor quota is the tool and means for enterprises to implement economic accounting; 5 labor quota provides conditions for labor competition. 12. Formulate the principle of labor quota: 1 The level of staff must be advanced and reasonable; 2 Correctly determine the proportional relationship of various types of personnel; 3 To make the best use of talents and personnel; 4 Pay attention to protect the health of workers. 13. Division of labor: According to the characteristics of the production technology of the enterprise and the reasonable organization of the production process, the scientific decomposition of the entire production process of the enterprise is carried out, and on this basis, each laborer is reasonably assigned to engage in a certain part of the work, and labor specialization is implemented. . 14. Labor Collaboration: It is to use appropriate forms to connect laborers engaged in various local tasks to complete a holistic work together. 15. Ways to reduce coal cost: 1 Strengthen production technology management, adopt new scientific and technological achievements; 2 Improve safety production; 3 Improve labor productivity; 4 Strengthen material management; 5 Reduce management costs. 16. The necessity of implementing comprehensive quality management in coal enterprises: 1 extensively adopting machine and machine system for production; 2 high safety production requirements; 3 product natural condition restrictions; 4 labor objects and labor places special; 5 labor division fine, production process contact Tight; 6 high input and high output in the production process; 7 users have high requirements on product variety and quality; 8 the quality of mining personnel is poor. 17. Status of China's coal mine management: China is a developing country. The level of coal mine mechanization is relatively low. There are many mines, low efficiency, and many underground workers have determined that coal mine safety is a prominent problem that restricts the development of the coal industry. In view of this, the situation of China's coal mine safety production is very serious. First, there are problems in safety management: 1 The concept of “safety first†is still not reliable, and the management mechanism is not perfect. 2 The security foundation is weak. 3 The production method is backward and the safety facilities are simple. 4 The overall quality of employees has declined. 5 With the development of the market economy, coal contracting projects across the country are relatively common. 6 Major scientific and technological problems in coal mines are difficult to implement, and major safety and technical issues are difficult to solve. 7 coal mine professional and technical personnel face the lack of green. 8 The management of the coal industry is relatively weak, the macro-control is weak, and the security management lacks strong institutional guarantees. Second, coal mine safety management measures: a, with scientific and technological progress as the guide, establish a modern coal mine safety management system project. b. Establish a safety management standardization system. C. Strengthen quality education and safety training.
18. The task of the excavation work organization is to properly organize the excavation strength and equipment and give full play to the enthusiasm and equipment efficiency of the excavating workers based on the correct understanding of the mining rules and the mining excavation ratio and the corresponding excavation workload required in different periods. To continuously improve the speed and efficiency of the tunneling, and often provide enough "three quantities" and spare working faces to meet the needs of the normal replacement of the working face and the continuous expansion of coal mining capacity. 19, the cycle progress determines the considerations: 1 allowable value of the control top distance; 2 integer multiple of the progress of the coal drop; 3 the allowable value of transport capacity; 4 the demand for the planned daily output. 20. Excavation work organization chart includes: mining cycle operation chart, labor organization table, and technical economic indicator table. 21.
