The general part is a new design of Xuchang mine which designed productive capacity is 3.0 Mt percent year. Xuchang mine lines in north-east of Jining , Shandong province. The traffic of road and railway is convenience to the mine. The width of the minefield is 4 km and the width is about 8 km, the well farmland total area is 32.3km2.The three is the main coal seam, and its average dip angle is 10 degree. The thickness of the mine is about 8.8 m in all. The proved reserves of the minefield are 357.33 Mt. The recoverable reserves are 262.4 Mt. The service life of the mine is 62.5 years. The normal flow of the mine is 1387 m3 percent hour and the max flow of the mine is 1928 m3 percent hour. The mine gas emission rate is 0.49 m3/t which can be recognized as low gas mine. The well farmland is two levels in combined development of vertical shaft and later slope; the cole mine is the longwall mining; the way of mine ventilation for the central paratactic type, later two wings diagonal type The working system “three-eight” is used in the Xuchang 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. 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. The topic of Special subject parts is bolt-anchor cable technology research. Mainly aims at the bolt support in our country and abroad present situation and some theory research of supporting. The main content of translation is the control of coal mine underground gas emission somet .English topic is: Control of gas emissions in underground coal mines. Keyword: Xuchang mine; two levels; Bolt support; Gas emission
