中文摘要：

随着煤矿开采技术的不断提高,巷道掘进机械化水平更加先进,掘进工作面延伸距离急剧增加,掘进工作面的供电模式也在不断更新与优化。文章以W1313运输巷掘进工作面供电系统为例,根据矿山已有的掘进设备型号以及供电需求计算分析了掘进作业的供电设计方案,并针对运输巷内的供电系统采用选择性漏电保护装置进行漏电保护,确保工作面掘进顺利进行。

英文摘要：

Based on improvement of coal mining technology, advancement of drivage mechanization level and rapid increase of extended distance in driving face, power supply pattern of driving face was also updated and optimized. Taking power supply system of driving face in W1313 transportation roadway as example in this paper, power supply design scheme of sinking operation was analyzed on the basis of power demand and existing type of heading equipment. Meanwhile, leakage protection was achieved by adopting selective electricity leakage protection device to reflect power supply system in transportation roadway, which ensured that working face would advance smoothly.
