3、ACTThis design includes of three parts: the general part, special subject part and translated part. The general part is a new design of Chensilou mine. Chensilou mine lines in north-west of Yongcheng in Henan province. The traffic of road and railway is convenience to the mine. The width of the mine
4、field is 2.8km ,the width is about 5.00 km,well farmland total area is 19.00km2.The two is the main coal seam, and its average dip angle is 9.73 degree. The thickness of the mine is about 7.5 m in all. The proved reserves of the minefield are 156.10 Mt. The recoverable reserves are 99.105 Mt. The de
5、signed productive capacity is 1.2Mt percent year, and the service life of the mine is 63.72years. The normal flow of the mine is 894 m3 percent hour and the max flow of the mine is 1200 m3 percent hour. The mineral well gas gushes the deal lower, for low gas mineral well.The well farmland is two lev
