生产过程机械化和自动化,需要在井下巷道内安装大量的机械设备、电气设备和液压设备以及使用高压供电等,这将增加发火的危险,特别是电气、机械设备的火灾危险。开采煤层的自然性上升,也将使火灾危险增加。有些生产过程的自动化,如运输设
Mechanization and automation of the production process require the installation of a large number of mechanical equipment, electrical equipment and hydraulic equipment and the use of high-voltage power supply in underground tunnels, which will increase the risk of fire, especially of electrical and mechanical equipment. The natural increase of the coal seam mining will also increase the risk of fire. Some of the automation of the production process, such as transport facilities
