In the field of geological structure is more complex, mine is located in the east wing to dish off southern, belongs to the prevention of mine, coal-dust explosion danger; This field, there are mainly eight layer can CaiMeiCeng, press buried depth from shallow to deep of 1, 3, 7, and 9, 10, 12, 17, 18, eight steps. After technical and economic comparison, coal production capacity of 900000 t/a, the first level to choose the flat adit, joint development plan, inclined coal mining methods to long wall type coal mining method, back comprehensive mechanized mining process. Assist transportation system and the main transport system, which separate auxiliary transportation system adopted international advanced auxiliary transportation equipment monorail, can meet the crane personnel, mechanical equipment, materials and the transportation of coal, need not use, but from the middle of tram direct face. Mine a level using zoning drawer-type ventilation system. All in all, through the comparison of the technical and economic aspects of the design of the pioneering scheme that coal mining meth
