摘　　要： 为减小煤矿地面单位原有供电网络由于级数较多且每级间隔较短造成的电量损耗、经常性跳闸、电压质量以及效率较低,并因此而造成的生产过程中的安全以及生产问题,本文以西山煤电某煤矿地面供电网络为研究背景,通过分析该矿地面单位多级供电网络现状以及所存在的具体供电网络级数问题,基于图论中的最短路径理论对供电网络最优级数进行研究,对供电网络结构进行优化,通过分析得出:该煤矿地面供电网络采用的最合理供电级数为2级。 In order to reduce the power consumption of the original power supply network of coal mine ground units due to the large number ofstages, the frequent tripping, voltage quality and efficiency am low, and the resulting safety and production problems in the production process.Based on the analysis of the status quo of the multi-stage power supply network and the specific power supply network series, the shortest paththeory in the graph theory is used to optimize the power supply network. Series of power to study the structure of the power supply network op-timization, through the analysis： the coal mine power supply network using the most reasonable level of power supply for the two.
