| Abstract: | There are some problems in power supply in many local coal mines. Supply transformers for underground coal mine well are earthed at neutral point. This paper analyzed the condition of power supply in local coal mines, advanced a new idea how to solve the problems of neutral ground. The way can satisfy the needs of power supply safely both area and underground coal mine well. |
