The 3 下610 working face of Jiangzhuang coal mine is the first fully mechanized caving face with high equipment power, and long distance power supply and full mechanized face equipment are used for the first time. According to the complicated conditions of power supply system, the power solutions are put forward from multiple aspects to solve the difficulties in the power supply system, which ensures the normal operation of full mechanized face equipment, and provides reference for the next installing power supply design of the working face.%蒋庄煤矿3下610工作面为矿井首个综放工作面，设备功率大、供电距离远、综机设备均属首次应用，针对供电系统的复杂情况因地制宜地提出了该供电方案，从多个方面入手解决工作面供电系统中的难点，保证了工作面综机设备的正常运转，为下一步的工作面安装供电设计提供了参考和借鉴。
