The general part is a new design of QiDong mine with a production of 1.2 million t/a. QiDong mine lines in the southeast of SuZhou County, AnHui province. The traffic of road and railway is very convenience to the mine. The run of the minefield is 9.2 km ,the width is about 5.0 km, well farmland total area is 35.4 km2. No. 61 is the main coal seam, and its dip angle is 10~15°, 14° for average. The thickness of the mine is about 3.6m respectively. The geological conditions of the minefield is relatively simple. The proved reserve of the minefield is 122.02 Mt. The recoverable reserve is 98.6 Mt. The designed productive capacity is 1.2 Mt/a, and the service life of the mine is 63.21 years. The normal water flow of the mine is 234 m3/h and the max flow of the mine is 360 m3/h. The relative gas emission rate of the mineral well is 12.76 m3/t, for high gas mineral well. The well farmland is a double-level with a shaft to expand. The coal is transported by the belt conveyer in the main roadway and 1 t mine car is used as the auxiliary transportation equipment. The way of mine ventilation is two wing opposite angle type. The working system “three-eight” is used in Qidong mine. It produces 330d/a. This general part 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 of the mine; 9. The ventilation and the safety operation of the mine; 10.The basic economic and technical norms. Special subject part of topics is: On the extraction treatment technology for gas of the 6201 fully mechanized caving face in Qidong mine. The title of the translation part is: High performance longwall extraction in large depth. Keywords:vertical development; inside slope development; two wing opposite angle type ventilation
