通常煤矿井下供电系统采用高压单母线分段和低压单母线的接线方式，其只能保证高压负荷的双电源供电，不能保证低压负荷的双电源供电，会导致局部通风机等低压重要负荷不能可靠供电而停风造成瓦斯积聚，引起瓦斯爆炸的恶性事故屡屡发生。同时，向煤（岩）与瓦斯（二氧化碳）突出矿井自救系统供风的空压机，井下移动瓦斯抽放泵也会因停电造成自救系统失效和瓦斯积聚而引发恶果。根据新修订的《煤矿安全规程》有关规定，提出了井下供电系统接线方式的设计方案，并对实际接线中代用母线联络配电装置存在的问题提出了解决方法，为井下供电系统设计提供了依据。

Before underground coal mine power supply system uses single bus bar section in the high voltage grid general line and low voltage grid. This power supply mode only guarantee the high pressure load of double power supply, but it cant guarantee low pressure load of double power supply. So the double lead to local fan and other important load can＇t be supplied reliably, then the wind stop causes gas accumulation, or even gas explosion of ongoing malignant accidents. At the same time, the pressure fan for the self-help system in coal （rock） and gas （carbon dioxide ） outburst mines also will out of work because caused power outages system failure and gas accumulated trigger consequences. According to the new revision of the ＂ Coal Mine Safety Regulations＂, the design scheme of line way is proposed in underground coal mine power supply system. And the actual connection alternative in bus bar contact switch issue of the solution, which provides basis for power supply system at underground coal mine.
