Abstract
This design contains three parts:the general part,the special part and the translated part.
The general part is a new design of Xu Chang mine belonging to Zi Bo mining bureau 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 Xu Chang mine filed lies in the north of Ji Ning about 8 kilometers.The transportation is convenient and.It covers 20.88 square kilometers. The boundary of the minefield run 5.8 kilometers on the strike and the pitch length is 3.6 kilometers.The three is the main coal seam,its dip angle is 4 degree and thickness is about 3m on average.
The proved reserves of the minefield are 90.6 million tons,and the recoverable reserves are 77.7335 million tons. The designed productive capacity is 1.2 million tons percent year, and the service life of the mine is 49.8 years. The normal flow of the mine is 200m3 percent hour and the max flow of the mine is 360m3 percent hour. The mineral well gas gushes is lower, It is a low gas mineral well.
 The working system is “three-eight”.One productive place meets the requirement. The mode of development about the mine is vertical development. The mine has two levels, the first level locates in the level of –260 meters, the second in the level of –495 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 1t solid car. Retrograde ventilation is used for Xu Chang coal mine in prophase and at anaphase defile ventilation is used at anaphase.
The title of the special subject part is “The technology research and effect analysis of the strip mining on under-buildings”.The paper overviews the technology research of the strip mining and analyzes the optimal method of the mining parameters，the influence-ng factors of surface movement parameters.Then the new formula of calculating surface movement parameters of strip mining is put forward .At last the effect of the spot surve-ring is analyzed.
The english topic of transportation part is Study on destressing technology for a roadway driven along goaf in a fully mechanized top-coal caving face.
Keywords:vertical shaft;strip district;comprehensive mechanization;overh-ead line elect-ric locomotive transport; centralized juxtapose ventilation.
