Maintenance and Management of Coal Mine Machinery and Equipment

With the development of science and technology, effectively promote the development of coal mine mechanization degree

With the development of science and technology, effectively promote the development of coal mine mechanization degree, but some coal mine machinery and equipment for a long time in heavy load or overload conditions, so as to the production of coal mine has brought greater security risks. Therefore, it is necessary to take effective measures to solve the above situation and minimize the incidence of coal mine safety accidents.
1: the use and maintenance of coal mine machinery and equipment
1.1: coal mine machinery equipment quality and performance uneven
Although coal mine machinery and equipment have been widely used in the production process of coal mines in China, they are often prone to uneven quality and performance, and the overall level of coal mining equipment is low. The main reason for the above phenomenon is that some coal mines in China are still at the traditional management level, and enterprise managers lack sufficient attention to the use and maintenance management of coal mine machinery and equipment, and capital investment is limited, as a result, the overall quality and performance parameters of coal mine machinery and equipment are quite different. At the same time, some large and medium-sized coal mining enterprises developed in the 1980 s. Coal mining has cited large and advanced fully mechanized mining machinery, with a high overall level. However, there is still a lack of unified norms and standards for the production and manufacturing of coal mining machinery and equipment, resulting in uneven quality and performance levels of coal mining machinery and equipment, affecting the service life and maintenance management level of coal mining machinery and equipment.
1.2: coal mine machinery and equipment working environment is relatively bad
Under normal circumstances, the working environment of coal mine is dark and humid, and the working space is relatively narrow, which leads to the poor working environment of coal mine machinery and equipment for a long time, such as water vapor, dust, noise, etc., which will not only affect the performance and service life of coal mine machinery and equipment, but also hinder the maintenance and management of coal mine machinery and equipment. In fact, most of the coal mine machinery and equipment for a long time in heavy load, vibration, high speed, impact, and lack of effective maintenance and maintenance, which has a serious impact on the performance of coal mine machinery and equipment, greatly reducing the safety performance and service life of the equipment. At the same time, some coal mine machinery and equipment because of its poor working conditions, for some small faults and problems can not be timely and effective solution, a long time will lead to coal mine machinery and equipment can not work properly, affecting the production efficiency of coal mining enterprises.
2: to enhance the use and maintenance of coal mine machinery and equipment management countermeasures
2.1: Improve the decision-making level of coal mine machinery and equipment use and maintenance management awareness
First of all, the Mechanical and Electrical Section needs to regularly organize the leaders of various production units to carry out training and education on relevant knowledge and skills, so that they can better understand and master the knowledge of the use and maintenance of coal mine machinery and equipment, and make them fully aware of the importance of the maintenance and management of coal mine machinery and equipment, so as to ensure the maintenance and management of coal mine machinery and equipment. Secondly, each section of the team can not continue to use, the scrapped materials should be reported to scrap in a timely manner, in order to replace them in a timely manner, such as bending deformation of the slide scraper, it is strictly prohibited to wait until the slide is broken can not be used normally to repair and replace, which will not only affect the efficiency of coal mine production, but also endanger the life safety of the staff. In the process of coal mine production, the rotating device of the endless rope winch and the roller of the belt conveyor should follow the basic operation law of the equipment, and do a good job in the use and maintenance management of the equipment according to the actual situation of its operation, so as to effectively improve the use efficiency of coal mine machinery and equipment.
2.2: do a good job in equipment maintenance spare parts management
(1): the quality of good maintenance spare parts. For coal mine machinery and equipment, the same equipment often has multiple suppliers, and the quality of spare parts produced by each supplier is uneven. The quality of spare parts will directly determine the service life of spare parts and the operation reliability of coal mine machinery and equipment. If the quality of spare parts for coal mine machinery and equipment is good, it can not only ensure that maintenance personnel find fault problems in a short time, and take effective measures to solve them, but also improve the service life of related parts.
(2): Management of replacement spare parts. In the process of dealing with the failure of coal mine machinery and equipment, if a spare part has quality problems, new spare parts need to be selected to replace it. Sometimes it may be due to the failure of coal mine machinery and equipment, but some of the spare parts are still intact. Discarding it will cause unnecessary waste of resources. At this time, it is necessary to do a good job in the management of replacing spare parts and establish a management and supervision mechanism for spare parts. For the replaced spare parts, it is best to appoint professionals to review them. If the spare parts are found to be intact, the maintenance personnel shall be punished accordingly to avoid the good use of spare parts resources.
(3): Strengthen the maintenance of available spare parts. In the process of maintenance of coal mine machinery and equipment, the damaged spare parts can be used after maintenance by certain means, and its performance is almost the same as that of the new spare parts, but it is often regarded as waste and wasted, which not only increases the maintenance cost, but also causes the waste of resources. At this time, it is necessary for maintenance personnel to repair damaged spare parts as much as possible, and it is strictly forbidden to pursue the intact rate too much, so as to effectively control the use and maintenance management costs of coal mine machinery and equipment.
2.3: perfect coal mine machinery and equipment management program
Coal mine mechanical and electrical department should improve the use and maintenance management procedures of coal mine machinery and equipment according to the actual situation, and formulate a set of practical management norms and standards, so that the daily maintenance of coal mine machinery and equipment can be carried out in an orderly manner. At the same time, the secretaries and team leaders of each district team are the first responsible persons for the use and maintenance management of coal mine machinery and equipment. They should have a comprehensive understanding and mastery of the management procedures of coal mine machinery and equipment, strictly operate according to the relevant norms and standards of the package mechanism, and assign the responsibility for the maintenance and management of coal mine machinery and equipment to people. For the existence of quality or safety problems of coal mine machinery and equipment is strictly prohibited to start operation, and each district team had better according to their own actual situation to build a set of systematic, integrity of coal mine machinery and equipment use, maintenance and management system, so as to ensure the efficiency of the use of mechanical and electrical equipment. No matter the size, model or importance of coal mine machinery and equipment, it is necessary to make detailed records of its use and maintenance process. Managers at all levels and management personnel of each district team should carry out systematic daily inspection according to the relevant requirements of coal mine machinery and equipment. If problems are found in the inspection process, effective measures should be taken to deal with them and relevant responsible persons should be punished. In addition, in the process of using and maintaining the management of coal mine machinery and equipment, it is necessary to link the leadership salary with the actual operation of the equipment, so as to better improve the leader's sense of responsibility and ensure that the coal mine machinery and equipment are carried out in strict accordance with the management procedures.
2.4: improve the overall level of coal mine machinery and equipment use and maintenance personnel
In order to ensure the use and maintenance of coal mine machinery and equipment management work in an orderly manner, we need to have a high-quality talent team. Coal mining enterprises need to regularly train and educate their employees on professional knowledge and skills, so that they can have a comprehensive understanding and mastery of the basic structure of the winch, the role of the winch planetary gear, the basic electrical schematic diagram, the fixing method of the wire rope, the transmission mode of the motor, and the wear requirements of the wire rope. When they have a comprehensive grasp of the above contents, they can be handy in the specific operation process, it can consciously carry out work according to the relevant requirements of coal mine machinery and equipment, so as to improve the safety, stability and reliability of mechanical equipment, and improve the operation efficiency of mechanical equipment. Coal mining enterprises can carry out professional knowledge training and education for employees every week, and test every 1 to 2 months, which can not only deepen their knowledge of machinery and equipment, but also improve the overall level of coal mine machinery and equipment use and maintenance personnel, effectively improve the efficiency of coal mining work, and improve the economic benefits of coal mining enterprises.
Starting from the use of coal mine machinery and equipment, the common faults in its operation process are analyzed, and the systematic maintenance management system is formulated, which can not only improve the operation efficiency of coal mine machinery and equipment, but also ensure the smooth progress of coal mine production and improve the economic benefits of coal mining enterprises.
