In the process of production and construction of coal mine enterprises, the electromechanical installation of coal mine is between civil engineering and coal mining. The installation of mechanical and electrical equipment in coal mine is an important link in the production process of coal mine, which has a vital impact on the production capacity of coal mine. With the rapid development of science and technology, the technical level of mechanical and electrical installation in coal mines is constantly improving, and the difficulty is becoming more and more serious. Therefore, coal mine electromechanical installation personnel should carefully analyze the problems in the installation process and take reasonable countermeasures to solve them, so as to ensure the close connection of all links and complete the installation task of electromechanical equipment with high quality.
1 Installation characteristics of mechanical and electrical equipment in coal mine
1) is very technical. At this stage, the production of enterprises gradually moves towards mechanization and automation with the support of high technology. Automation and intelligentization of coal mine machinery and equipment are conducive to improving the safety of coal mine production, reducing the work pressure of front-line operators and reducing the accident rate and economic losses caused by irregular operation behavior. In the production process of coal mining enterprises, the upgrading and development of mechanical and electrical equipment in coal mines have greatly improved the production efficiency. However, the installation of mechanical and electrical equipment is becoming more and more complicated because of its higher technical content, and the installation task is getting bigger and bigger. 2) the number is huge. The increasing demand for coal resources in various industries has promoted the continuous improvement of the production capacity of coal mining enterprises, and at the same time, the production scale of coal mines is also expanding day by day, and the number of production equipment is also increasing. In this case, the working pressure of coal mine mechanical and electrical equipment installation workers is also rising [1]. In recent years, domestic coal mine production enterprises attach great importance to safety management, and all kinds of production equipment in front-line production operations are becoming more and more complicated, such as pumping equipment, mining equipment, fan equipment, etc. These equipment effectively support the coal mine production behavior and provide the necessary guarantee for coal mine production efficiency, normal drainage of accumulated water and underground air circulation. However, there are more and more electromechanical equipment, which makes the installation more difficult and the load increases accordingly. 3) High complexity. For coal mine production enterprises, mechanical and electrical equipment installation, as an engineering project covering underground and underground construction, has high complexity. The construction content involves mechanical automation and mechanical engineering technology, which needs the support of information technology and numerical control technology, and applies subject knowledge in combination with equipment installation requirements and actual working environment. In this case, the coal mine mechanical and electrical equipment installation operators should have solid basic knowledge and excellent operation ability to ensure efficient and high-quality installation of various mechanical and electrical equipment.
2. Some problems existing in coal mine electromechanical installation and operation.
1) installation technical problems. The production of coal mining enterprises is special, so the installation quality of mechanical and electrical equipment in coal mines should follow the principle of standardization. However, at present, there are some problems in the installation of mechanical and electrical equipment in coal mines, such as weak technology and random installation, which leads to low operating efficiency of mechanical and electrical equipment and even frequent failures. At present, there is a serious shortage of compound technicians for coal mine equipment installation, and the installation quality cannot be effectively guaranteed. There are different degrees of deviation between some equipment and important nodes in the installation site, which seriously restricts coal mine production enterprises [2]. 2) Engineering design problems. Pre-installation design of mechanical and electrical equipment has a decisive influence on equipment construction efficiency, project cost and normal operation. Unreasonable installation design will delay the construction progress and increase the construction difficulty and cost. Many designers recommend a construction enterprise or a product model for their own benefit, which is difficult to effectively ensure the construction quality and is not conducive to the normal production of coal enterprises. 3) Installation problems. In the process of coal mine civil construction and subsequent production, coal mine electromechanical installation is an intermediate link and a key link. It should be effectively coordinated with other construction operations to promote the sharing of information resources in different links of civil engineering, comprehensive excavation and equipment installation. However, at this stage, the communication between all aspects of coal mining enterprises is not smooth, and the information sources are different, which leads to the installation of mechanical and electrical equipment being affected. In addition, many installation processes have potential safety hazards, such as unqualified terminals, sealing rings and insulating sleeves; The cover plate and connecting nozzle of flameproof enclosure are damaged; The contact area of the surface of the static contact does not meet the established requirements. , causing potential safety hazards and a high probability of fire.
3 coal mine mechanical and electrical equipment installation effective countermeasures
1) scientifically coordinate the installation work. Coal mine electromechanical installation project has relatively high requirements for construction safety, with many nodes and construction links, involving a variety of engineering equipment, and extremely strict requirements for installation quality [4]. As a systematic project, the installation of mechanical and electrical equipment in coal mine must be coordinated scientifically and comprehensively, and the quality of installation and construction must be guaranteed through strict organization and management. Before the installation of mechanical and electrical equipment in coal mine, we should first attach great importance to the construction organization design, do a good job of coordination and division of labor seriously. Managers, supervisors and front-line installation workers should perform their respective duties (as shown in figure 1) to ensure the smooth installation of mechanical and electrical equipment. Secondly, the installation scheme of mechanical and electrical equipment should be discussed in depth, and the reliability and safety of the scheme should be demonstrated in many aspects, and its scientificity and economy should be evaluated. Installation and operation should strictly follow the established specifications to prevent potential safety hazards and operational accidents. In addition, managers should also pay attention to the scientific scheduling of mechanical and electrical equipment installation and promote the installation progress on the basis of ensuring the installation quality. 2) Improve the comprehensive quality of installation workers. The installation technology of mechanical and electrical equipment in coal mine is relatively high, so the installation workers should constantly improve their professional quality, ensure solid professional basic knowledge and excellent operation skills, and ensure the installation and construction quality of mechanical and electrical equipment. Because of the high risk in the coal production industry, the talents in this industry are highly mobile, as are the mechanical and electrical installation workers, and their comprehensive qualities are uneven. Therefore, coal mine production enterprises should attach great importance to personnel training, organize electromechanical installation personnel to participate in pre-job training, rotation training and on-the-job education, strengthen the overall quality of electromechanical installation team and electromechanical installation construction quality, and promote safety production management. 3) Scientifically organize installation and construction operations. The safety and reliability requirements of mechanical and electrical equipment installation in coal mines are relatively high. Installation workers should install all kinds of equipment in strict accordance with operating specifications and established procedures to ensure the scientificity and reliability of mechanical and electrical equipment installation. For example, the installation and operation of explosion-proof system should be fully considered when installing electrical switches to avoid gas explosion accidents. When installing the derrick, the principle of assembly and installation layer by layer should be strictly followed, and the operation should be carried out according to the grouting technology, so as to avoid the unfinished engineering quantity caused by irregular construction and ensure the installation quality to meet the requirements of established design standards [5].
4 conclusion
In the process of mechanical and electrical equipment installation in coal mines, due to the influence of various factors, a series of installation problems often occur, which not only bring serious security risks to the safety production of enterprises, restrict the normal production of enterprises, but also reduce the social and economic benefits created by coal mining enterprises. Therefore, coal mine production enterprises should attach great importance to the installation of mechanical and electrical equipment, and take effective measures to improve the present situation, strengthen the comprehensive quality and professional level of installation technicians, and continuously improve the installation quality of mechanical and electrical equipment in coal mines in order to create favorable preconditions for coal mine production enterprises to realize scientific and modern production.
