当前我国的电力供应严重不足,但在煤矿生产中浪费电力的现象还比较严重,例如:煤矿中的通风、压风系统中的漏风;排水系统中的漏水、阻堵;采掘机械的不合理匹配,设备长时间的空载、半载运行和电压等级不当等问题造成煤矿用电浪费和吨煤电耗不合理上升。为改变上述电力浪费现象,现就改进煤矿的节电途径进行探讨。一、加强用电管理,打破煤矿用电“大锅饭”的管理办法,在各用电点安装用电计量装置在统配煤矿中生产每吨原煤的电耗有的高达92度,而有的仅为14度,就同样的客观条件下矿井消耗电力往往相差颇大,目前在
At present, the power supply in our country is seriously deficient, but the power wasted in the production of coal mines is still quite serious. For example, air leakage in coal mines, air leakage in air-pressure systems, water leakage and blocking in drainage systems, and unreasonable matching of mining machinery , A long time no-load equipment, half-load operation and improper voltage levels and other issues caused by coal mine electricity waste and tons of coal power consumption unreasonable rise. In order to change the above phenomenon of power waste, we will discuss ways to improve the power saving in coal mines. First, to strengthen electricity management, to break the management of coal mines “big pot of rice” in the electricity point of the installation of electricity metering devices in the United state coal mine production per ton of raw coal consumption as high as 92 degrees, while others only 14 degrees, the same objective conditions, the power consumption of mines are often quite different, at present
