4、ialiang mine is located in South of Shuozhou City, Shanxi Province. It is very convenient to get to the mine in terms of both highway and railway. The length of the coalfield is about 10.16km and the width is about 6.12km，and the total area is 59.531 km2.The third and the ninth is the main coal seam

5、，and their dip angle is 210 degree, the average dip angle is 5 degree . The thickness of the mine is about 6.62、11.96m respectively.The geologic structure of this coalfield is simple.The recoverable reserves of the coalfield are 1580.2492 million tons，and the minable reserves are 1126.6387 million t

6、ons. The designed productive capacity is 10.0 million tons percent year，and the service life of the mine is 80.47 years. The normal flow of the mine is 304 m3/h and the max flow of the mine is 464 m3/h. The relative mine gas gush is 1.41m3/t ,so it is a low gas mine. The mine is a single level in sh
