WuLong Mine through field visits, in conjunction with the existing level of production plant and the prospects for future development in the power supply system on the basis of the relevant provisions of the coal production industry further standardize and improve. WuLong Coal Mine is 50 million tons and coal mines, over a hundred years of history, many of which are original to introduce foreign. With the development of enterprises, the current power supply system can not guarantee the safe and reliable power supply. This design is based on the characteristics of the existing power supply system, for some equipment and load distribution is improved to meet the power supply reliability and security. power system design include ：load calculations, ground substations design, short circuit current calculations, ground high-low voltage equipment selection, protection devices, Substation lightning protection and grounding. From the design of the power supply system in different parts of the two roads 35kV power line, the main 6kV transformers into the single-parent separately to the Mining wiring electricity. According to the characteristics of coal supply system, the design of the main lines are the largest operation of the system means the set of lines and equipment and to choose. WuLongCoal Mine 35kV power supply system design is only part of the power supply system Inoue. Considering the fifteen years’ service of WuLong Coal Mine, in order to ensure the security of electricity supply, reliable, the paper designs the engineering system which is reasonable for WuLong Mine from the economic and technical aspects.
