The general part is a new design of Qi Dong coal mine located in southeast of Suzhou whose production capacity is 1.2 Mt per year.It has ten chapters as follows:the outline of mine and mine field geology, boundary and reserves, working system and productive capacity and service life, development method of the mine, the main roadways, coal mining method and layout or roadways in working area,transportation of underground, mine lifting, mine ventilation and safety, main technique—economic induces. The QI Dong mine filed lies in the north of J southeast of Suzhou about 20 kilometers.The transportation is convenient and.It covers 23.16 square kilometers. The boundary of the minefield run 9 kilometers on the strike and the pitch length is 4 kilometers. Three is the main coal seam,its dip angle is 14 degree and thickness is about 4.70m on average. The proved reserves of the minefield are 157.6 million tons,and the recoverable reserves are 92.4 million tons. The designed productive capacity is 1.2 million tons percent year, and the service life of the mine is 55 years. The normal flow of the mine is 437.06m3 percent hour and the max flow of the mine is 586.10m3 percent hour. The mineral well gas gushes is high, It is a high gas mineral well. The working system is “three-eight”.One productive place meets the requirement. The mode of development this design uses a duel-vertical shaft and inclined shaft two-level development method. The mine has two levels, the first level locates in the level of –650 meters, the second in the level of –900 meters.The main shaft uses skip hoisting and the auxiliary shaft adopts cage hoisting. The working face adopts long wall retreating to the strike.Its length is 180 meters.The technology of the working face is the full-mechanized mining.Belt Conveyor to transit coal is used chiefly to transport coal, the auxiliary transportation uses 1.5t solid car. Districts ventilation is used for Xu Chang coal mine. The design applies strip preparation against the first district of South Two which divided into 11 districts totally, and conducted coal conveyance, ventilation, gangue conveyance and electricity designing. The monographic study entitled " Pressure behavior and control of deep mine ", with the theoretical research related engineering test, conducted a detailed pressure observation data collection and processing, gave the deformation and convergence law of soft rock roadway,with law we can recommend some control measures which really have a important influence. The english topic of translation part is Coal pillar load calculation by pressure arch theory and near field extraction ratio.
