煤矿掘进工作面远距离供电方式探究

Discussion on Long-distance Power Supply Mode of Coal Mine Heading Face

针对掘进工作面远距离供电线路压降大、过流保护校验不合格等问题,结合矿井远距离掘进工程实际,阐述了远距离掘进供电优缺点,并针对性提出了优化改进方法,分析计算了远距离掘进供电方式的最佳配置参数,指出了应用该供电方式的注意事项,望对类似掘进工作面远距离供电工程有所借鉴。

In view of the large pressure drop of the long-distance power supply line and the unqualified over-current protection verification,combined with the actual long-distance tunneling project of the mine,this paper expounded the advantages and disadvantages of long-distance tunneling power supply,proposed the optimization and improvement methods,analyzed and calculated the optimal configuration parameters of the long-distance tunneling power supply mode,and pointed out the precautions for applying the power supply mode.It is expected to provide reference for the long-distance power supply project in similar tunneling face.
