5、n part.The general part is a new design for Changcun coal mine.Changcun coal mine is located in Yima city of Henan province.The traffic of road and railway is very convenience to the mine.Its about 4.00 km on the strike and 3.61 km on the dip,with the 14.42 km2 total horizontal area.The 2-1 and 2-3
6、are the main coal seams,and tis dip angle is 912 degree.The thickness of the mine is about 13.68 m in all.The geologic structure of this coalfield is medium.The normal flow of the mine is 145 m3/h,and the maximum flow of the mine is 375 m3/h.The relative mine gas gush is 2.0 m3/t and the absolute gu
7、sh is 6.5 m3/t,so it is a low gas mine and its a coal seam liable to explosion.The recoverable reserves of the coalfield are 273.65 million tons,and the minable reserves are 182.82 million tons.The designed productive capacity is 2.4 million tons percent year,and the service life of the coal mine is
8、 54.41 years.The coalfield development is vertical shaft develop.The workable coal seam is divided into two mining levels.The first level is at+120 m and the second level is at-100 m.The first level is devided into two mining area,and the second level is devided into one mining area and one strip.Th
9、e south two mining district is designed as the initial district,there are 20 sections and the length of working face is 230 m,uses fully-mechanized coal mining technology to exploit coal,falling to dispose worked out section.In the Changcun coal mine,it produced 330 days per year.“Three-eight”as the
10、 working system is used in the coal mine,with two teams mining,and one overhauling.Every mining team makes three working cycle,six working cycle a day.The advance of working cycle is 0.8 m,daily production is 6360.36t.Main roadway makes use of belt conveyor to transport coal resource,and mine car wi
11、th 1.5 ton to be assistant transport.The main shaft uses two sets of double 12 t skips to lift coal with a balance hammer and the auxiliary shaft uses a twins narrow1.5 t four-car double-deck cage and a wide 1.5 t four-car double-deck cage to lift material and personnel transportation.The ventilatio
