鹤岗矿务局新一矿综采队,自1981年以来,在平均倾角31～33°,最大倾角36°的煤层中,使用综采设备取得了良好效果。三年来生产原煤70多万吨,为大倾角工作面使用综机采煤积累了经验。我矿综采队先后在矿井北部10号层11号层,两层煤共4个工作面进行了回采。10号层煤厚2.4m,平均倾角31°,最大倾角35°;11号层煤厚4.2m,平均倾角33°,最大倾角36°。分层开采,上层综机开采,采高2.5m,同时铺金属
Since its establishment in 1981, it has achieved good results using fully mechanized mining equipment in coal seams with average inclination of 31-33 ° and maximum inclination of 36 °. Over the past three years, it has produced more than 700,000 tons of raw coal and accumulated experience in using coal pans for large-dip work surfaces. Our mine fully mechanized coal mining team has mine in the north of No. 10 layer 11, two layers of coal a total of 4 face mining. On the 10th floor, the coal thickness is 2.4m with an average inclination of 31 ° and a maximum inclination of 35 °. The thickness of No.11 coal is 4.2m with an average inclination of 33 ° and a maximum inclination of 36 °. Hierarchical mining, mining upper comprehensive mechanization, mining height 2.5m, at the same time paving metal
