大河边煤矿是1966年3月开始建设,1970年6月局部简易投产,采取边生产边建设的新矿井。煤层群可采层数12层,总厚度16.37米,平均层厚1.37米,煤层倾角23～30度,平均29度。又是超级瓦斯矿井,相对瓦斯涌出量24.8米~3/吨,矿井瓦斯涌出量9.77米~3/分。所采各煤层均有自然发火和煤尘爆炸危险,煤尘爆炸指数达40%以上。采煤方法为单一长壁和倾斜分层。几年来在毛主席革命路线指引下,我们高举“鞍钢宪法”旗帜,坚持以阶级斗争为 Dahebian Coal Mine started construction in March 1966 and was briefly put into operation in June 1970, taking the construction of new mines while producing. Coal seam group recoverable number of layers 12, the total thickness of 16.37 meters, the average thickness of 1.37 meters, coal seam angle of 23 to 30 degrees, an average of 29 degrees. Another super gas mine, the relative gas emission 24.8 m ~ 3 / ton, mine gas emission 9.77 m ~ 3 / min. All coal seams are naturally flammable and coal dust explosion danger, coal dust explosion index of more than 40%. Coal mining methods for a single longwall and inclined stratification. In the past few years, under the guidance of Chairman Mao’s revolutionary line, we have held the banner of “Ansteel Constitution” and adhered to the principle of class struggle
