我矿是一个年产45万吨煤炭的地力煤矿。由35KV 电源供电,经降压站降至6KV下井。经中央变电所、采区变电所,再降为660V 供给各采掘工作面和峒室的用电设备。近几年,随着生产的发展,井下采掘条件的变化,给井下供电工作带来一些新的课题。针对新情况,我们按照《煤矿安全规程》 My mine is a geologic coal mine with an annual output of 450,000 tons of coal. By 35KV power supply, the buck station down to 6KV down. The central substation, mining area substation, and then down to 660V for the mining face and the room of the electrical equipment. In recent years, with the development of production and the change of underground mining conditions, some new topics have been brought to underground power supply work. In response to the new situation, we follow the “Coal Mine Safety Regulations”
