The waste filling working face can effectively solve the problem of Environmental Protection of waste rock produced in the production process of coal mine, the safety problem caused by frequent pulling and shifting equipment trains can be effectively solved by using the way of long-distance power supply and liquid distribution. Taking the successful application of long-distance power supply and liquid supply in CT201 gangue filling working face in Zhongtianhechuang coal mine as an example, the total voltage drop at the start of the maximum power equipment in the working face is calculated, the actual starting pressure drop is used to verify the design, and the pump station and the long-distance liquid supply system are described, the feasibility of long-distance liquid supply is proved by calculating the flow demand of pump station and the total pressure drop of long-distance liquid supply and return pipeline, monorail crane and rubber hose between frames. The project summarized a set of relatively mature gangue filling working face’s long-distance power supply liquid application experience.
