我国煤矿供电基础条件差、可靠性低，应对突然停电事故的能力差，特别对千米深井的煤矿，备有一套应急电 源是十分必要的。唐口煤业公司建设了一套3000KW 柴油发电机组作为矿井的应急备用电源，当发生停电事故时，可为副井 提升运输及其它重要场所提供电源。该项目目前已在唐口煤业公司正常运行，对保证唐口煤业公司千米深井的安全生产、保 障井下一线作业人员的生命安全，起着至关重要的作用

The capacity to cope with sudden power failure is very poor because China's basic condition of coal mine power supply is poor, and the reliability is low. It is necessary for the kilometer deep coal mine to have a set of emergency power supply. Tangkou Coal Company built a set of 3000kW diesel generating sets as emergency power supply. When the blackout occurred, it can provide the power supply for auxiliary shaft hoisting and transportation and other important places. The project is currently in the normal operation at Tangkou Coal Company. It is very important for ensuring the safety in production, guaranting the safety of 1000m deep underground frontline operational staff's life.
