5、y; the economic and technologic index of the mine.The Liangshuijing mine field lies in the yulin city of Shanxi province, the total area of the mine is 68.08 km2. Its about 6.84 km on the strike and 9.81 km on the dip. There is three minable coal seam: No.4-2,No.5-2 and No.5-3, and the average thick
6、ness of the seam is 3 m,2.4m and 2.78 m. They are stable and fluty inclined. The dip angle is from 0 degree to 3 degree, and is 1 degree on average. The normal flow of the mine is 120m3/h, and the maximum mine flow is 400 m3/h. The absolute gas emission rate of mine is 8.18 m3/min which belongs to l
7、ow gas mine. The seams dont have self-combustion tendency, and the coal dust has explosion hazard.The productive capacity of Liangshuiijng mine is 4.0 million tons per year, and its service life is 78.6 years. The development of the mine is inclined shaft development with two mining levels Designed
8、first mining district makes use of the method of the panel rise. The length of working face is 240 m, which uses fully-mechanized longwall mining method. The working system is “foure-six” which produces 330 d/a.Main roadway makes use of belt conveyor to transport coal resource, and the assistant tra
