5、ngle is 823 degree. The thickness of the mine is about 3.5m in all. The geologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 282.07 million tons, and the minable reserves are 204.54 million tons. The designed productive capacity is 24 million tons percent year

6、, and the service life of the mine is 65.56 years. The normal flow of the mine is 894m3 per hour and the max flow of the mine is 1087m3 per hour. The relative mine gas gush is 0.57 m3/t and the absolute gush is 2.0 m3/min, so it is a low gas mine. The mine is two level to develop. Te central laneway
