由于煤矿生产条件和生产环节的复杂性,这对机电设备的安全运行提出了更高、更严格的要求。在我国煤矿的固定资产总额中,有55%～65%是机电设备和设施,所花费的工资、能耗、油脂、配件、维修费用等的总和要占煤炭生产成本的40%以上。笔者介绍了煤矿机电故障的类型及维修方式,并提出控制机电设备故障的预防措施。 Due to the complexity of coal production conditions and production processes, this puts forward higher and stricter requirements on the safe operation of mechanical and electrical equipment. Among the total fixed assets in China’s coal mines, 55% to 65% are mechanical and electrical equipment and facilities, and the sum of wages, energy consumption, oil, parts, maintenance costs and so on accounts for over 40% of the total coal production costs. The author introduced the type of mine mechanical and electrical failure and maintenance methods, and put forward preventive measures to control mechanical and electrical equipment failure.
