Chensilou mine lines in north-west of Yongcheng in Henan province. The traffic of road and railway is convenience to the mine. The width of the minefield is 4.40 km ,the width is about 8.70 km,well farmland total area is 34.20km2.The two is the main coal seam, and its average dip angle is 10degree. The thickness of the mine is about 3.25 m in all. The proved reserves of the minefield are 206.49 Mt. The recoverable reserves are 125.13 Mt. The designed productive capacity is 1.5 Mt percent year, and the service life of the mine is 64.17 years. The normal flow of the mine is 894 m3 percent hour and the max flow of the mine is 1200 m3 percent hour. The mineral well gas gushes the deal lower, for low gas mineral well.Mine geological conditions under the proposed development schemes for the four technically feasible. Option One: Single-level plus dark inclined shaft development; Option Two: One level down the open shaft; Option Three: Vertical two-level development (transport arranged in rocks in the roadway, a direct extension shaft deep); program four: two horizontal shaft development (Transportation Roadway layout in coal, direct extension shaft deep). Through technical and economic comparison, the final three as the best program to determine the program. A level elevation of -650 m, -850 m elevation of the second levelMine shaft of two levels to explore; fully mechanized mining overall high-mining method; mine ventilation for the two wings on the diagonal.The working system “four-six” is used in the Chensilou mine. It produced 330 d/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 of panels; 6. Preparation method - with area tunnel arrangement; 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.Thematic part of the topic of coal mining on the ground of the bridge, the main pin surface deformation and described the impact of the bridge structure, and then put forward from a number of coal mining solutionsTranslation part of main contentses is The Structure Statics Analysis and Transient Dynamics Analysis of Hydraulic Support.English topic is: The Structure Statics Analysis and Transient Dynamics Analysis of Hydraulic Support.Keywords : Chensilou coal; shaft; with a mere arrangement;
