The general part is a new design of liangshuijing mine. Liangshuijing mine l

4、ines in North of YuLin and South of ShenMu in ShanXi province. The traffic of road and railway is very convenience to the mine. The run of the minefield is 6.84 km ,the width is about 9.81 km，well farmland total area is 62.71km2.The 4-2 and 5-2 is the main coal seam, and its dip angle is 1degree. Th

5、e thickness of the mine is about 5.52m in all. The proved reserves of the minefield are 368.02 million tons. The recoverable reserves are 281.82 million tons. The designed productive capacity is 2.4 million tons percent year, and the service life of the mine is 83.88 years. The normal flow of the mi

6、ne is 327 m3 percent hour and the max flow of the mine is 510 m3 percent hour. The mineral well gas gushes the deal lower, for low gas mineral well. It is coal of spontaneous combustion tendency, and its a coal seam liable to explosion.The mine is two levels in an inclined well to expand. The main t

The ventilation method is fully caving method to deal with g

8、oaf.。The working system “four-six” is used in the Liangshuijing mine. It produced 330d/a.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

9、 of panels; 6. The method used in coal mining; 7. Transportation of the underground; 8.The lifting of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms.Special subject parts of topics is the shallow seam mining rock layer controlling of Lian

10、gshuijing mine. It is made an analysis of liangshuijing mine by the rock layer movement rule of the shallow seam longwall working face.Translation part of main contentses is Longwall mining-induced fault reactivation and delayed subsidence ground movement in British coalfields.目 录一般部分01 井田概况及地质特征11.
