This design includes ten chapters. 1. An outline of the mine field geology. 2. Boundary and the reserves of mine. 3. The service life and working system of mine. 4. development engineering of coalfield. 5. The layout of panels. 6. The method used in coal mining. 7. Transportation of the underground. 8. The lifting system of the mine. 9. The ventilation and the safety operation of the mine. 10. The basic economic and technical norms.Sangshuping in coal mine because of hancheng mining district, to the west of the Yellow River is the northernmost town, is apart from the HanCheng straight from about for 15 km. Administrative districts belongs to sangshuping town of jurisdiction. The run of the mine field is 3.21~4.3 km,the width is about3.8 km,mine farmland total area is 21.1 km 2. The four nine and eleven is the main coal seam. The coalfield geological condition is simple.The proved reserves of the coalfield are 174.19 million tons. The recoverable reserves are 140.75 million tons. The normal flow of the mine is 500 m3 percent hour and the max flow of the mine is 680m3 percent hour. The mineral gas gushes the deal lower,for low gas mineral mine.The mine farmland in an inclined mine to expand.The main transportation uses the adhesive tape transportation opporteunity coal.The working system “four-six” is used in the Pingshuo No.3 mine. It produced 330d/a.The development of the mine is double level with a main shaft and an auxiliary vertical shaft. The number of the working faces is only one. Comprehensive mechanization puts in the top coal technology is the mining method. Several belt conveyers undertake the job of coal transport in the mine, while the auxiliary transportation system depends on the mine cars. The ventilation type in the early stage is centralized juxtapose. In the late stage two air shafts in the boundary should be driven. The ventilation method is extraction.The working days in a year are 330. Everyday it takes 16 hours in lifting the coal. The working system in the mine is “four-six”.目录中 国 矿 业 大 学
