煤矿井下直流牵引网络中杂散电流分布

An Analysis on the Stray Current Resulted from DC Traction Networks in the Pits

煤矿井下电机车牵引网络的杂散电流是引发瓦斯爆炸和雷管先期引爆的原因之一。通过对杂散电流形成机理的分析讨论，提出了防治杂散电流的必要措施。

The stray current resulted from the traction networks of electrical locomotives is one of the causes of gas explosion and premature explosion from detonator. By discussing the generation mechanism of stray current,the necessary measures for preventing and controlling stray current are suggested in this paper.
