Research And Application Of Power Supply And Liquid Supply System Optimization And Automation Technology For Fully Mechanized Mining Face

In this paper,taking the design of 3108 fully-mechanized mining face of xinyuan company of yangcoal group as the background,through the optimization design of the 3108 fully-mechanized mining face of xinyuan company as the background,remote power supply is carried out for the working slip with high rate first,the location of transformer and frequency converter is determined once,which reduces the equipment shift and improves the working efficiency.A reliable power supply system is proposed.Inverter control is applied to the work slip,which reduces the starting torque,eliminates the impact of high-power inverter start on the power grid,and improves the power supply quality.According to the principles of short circuit current,starting current and cable calibration,the power supply of high-voltage switch transformer,especially the working slip frequency converter with long-distance power supply is verified by theoretical calculation,and the reasonable equipment and cable selection is obtained,and a reliable power supply system is finally formulated.Second,the traditional fluid for system long-distance intelligent integration system transformation,the successful application of the system,realizes the remote liquor system unattended,save labor costs,system of the fully enclosed with liquid can guarantee the cleanliness of the system,basic to eliminate the emulsion of run,run,drip,leakage phenomenon,such as the consumption of emulsion is decreased obviously.Finally,in order to further improve the ability of security protection,quicken the steps of intensive production,to the automation of 3108 fully mechanized coal face s company technical transformation,support with machine operation,the position of shearer cutting system,the real-time accurate positioning and memory for liquor,transportation system,video monitoring,mine pressure observation,voice communication,automation,such as security ability,cost control,and the intensity of labor to improve results.The automation work surface based on power supply system,liquid supply system and centralized control makes the material cost decrease obviously,labor cost decrease,reduce human cost and improve efficiency,especially the output is improved greatly,and the economic benefit increases obviously.In a word,through the reliable,safe,economic and reasonable optimization design of fully mechanized mining face,it is helpful to improve the economic benefits and ensure the safety of production.It provides reference basis for the design of fully mechanized mining face in similar mines.
