4、ocated in Jinxiang which comes within the jurisdiction of Jining in Shandong province. It is very convenient to get to the mine in terms of both highway and railway. The length of the coalfield is 3.9km,the width is about 3km，and the total area is 13.97km2.The fifteenth are the main coal seams, and
5、its dip angle is 212 degree. The thickness of the mine is about 7.5m in all. The geologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 147.75 million tons,and the minable reserves are 124.97 million tons. The designed productive capacity is 1.5 million tons per
6、cent year, and the service life of the mine is 59.50 years. The normal flow of the mine is 86m3 per hour and the max flow of the mine is 99 m3 per hour. The relative mine gas gush is 1.732 m3/t and the absolute gush is 6.866 m3/min, so it is a low gas mine. The mine is a single level in two shafts t
7、o develop. Te central laneway uses Belt Conveyor to transit coal, and trolley wagons are used for accessorial transportation in the roadway.The ventilation mode of this mine is center juxtapose form.The “three-eight” working system is used in the Zhaizhen mine. It produces for 330 days a year. This
