The general part is a new design for Dongping mine. Dongping mine is located in Yuxian which comes within the jurisd

4、iction of Yangquan in Shanxi province. It is very convenient to get to the mine in terms of both highway and railway. The length of the coalfield is 5.20km,the width is about 3.42km，and the total area is 14km2.The fifth are the main coal seams, and its dip angle is 023 degree. The thickness of the m

5、ine is about 8.5m in all. The geologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 167.58 million tons,and the minable reserves are 133.45 million tons. The designed productive capacity is 1.8 million tons percent year, and the service life of the mine is 57.0

6、 years. The normal flow of the mine is 3.75m3 per hour and the max flow of the mine is 5.63 m3 per hour. The relative mine gas gush is 1.30 m3/t and the absolute gush is 1.85 m3/min,so it is a low gas mine. The mine is a single level in two slopes to develop. The central laneway uses Belt Conveyor t

7、o transit coal,and trolley wagons are used for accessorial transportation in the roadway.The ventilation mode of this mine is center juxtapose form.The “three-eight” working system is used in the Dongping mine. It produces for 330 days a year. This design includes ten chapters: 1.An outline of the m

The method used in coal mining; 7. Underground transportation of the mine; 8.The lifting of the mine; 9. The ventilation and th

9、e safety operation of the mine; 10.The basic economic and technical norms of the designed mine.The topic of special subject parts is the Summarize of the Tecnique of Support in Fully-mechanized top coal caving face. It mainly Discuss some Methods of Support in Fully-mechanized top coal caving face.T

10、ranslation part is aboat the application of stability of mining in fully mechanized top coal caving face.The English title is “Mine Stability with Application of Sublevel Caving Schemes”.Keywords: Slope; Single level; District； Center juxtapose ventilation目录一般部分1 矿区概述及井田地质特征21.1矿区概述21.1.1井田地理位置及范围21
