The length of the coalfield is 3.6km,the width is about 2.6km，and the total area is 9.36km.The second is the main coal seam, and its dip angle is 725 degree. The thickness of the mine
5、 is about 9.0m in all. The geologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 146.87 million tons, and the minable reserves are 98.67million tons. The designed productive capacity is 1.5 million tons percent year, and the service life of the mine is 50.6year
6、s. The normal flow of the mine is 500mper hour and the max flow of the mine is 650 m per hour. The relative mine gas gush is 3.84m/t and the absolute gush is 11.2 m/min, so it is a low gas mine. The mine is vertical shaft development with two mining levels and the extension of vertical shaft. The ce
