The general part is a new design of 1.8Mt/a for Jining Mine No.2,it 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 panelen; 6. The mining method used in this coal mine; 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. Jining Mine No.2 lines in south of Jining city in ShangDong province. The traffic of road and railway is very convenience to the mine. The run of the minefield is 5.59km,the width is about 5.85km，well farmland total area is16.83km2.The three is the main coal seam, and its dip angle is 7 degree. The thickness of the mine is about 6.7m in all. Geologic structure of coalfield is simple, the proved reserves of the minefield are 209 million tons,and the recoverable reserves are 150million tons. The designed productive capacity is 1.8million tons percent year, and the service life of the mine is 59.7years. The normal flow
