我矿37号层属上侏罗系鸡西群城子河含煤层,复合煤层。该煤层在我矿全区发育,赋存稳定,属主采煤层。该煤层厚2.0m～2.8m。平均厚2.4m。其直接顶为0.5m～0.7m 厚的煤页岩及页岩,老顶为细砂岩 f=4,8m～20m,底板为细砂岩 f=4.2。由于受地质构造的影响,局部地域适合综合机械化开采,其余均适宜高档机械化开采。1.工作面条件:1.1.工作面地质及开采情况:该工作面位于一采区北部,采用走向长壁后退式开采方法,回风巷为+40m 水平,运输巷为+20m 水平,阶段垂高20m,工作面长160m,
I mine No. 37 layer is on the Jurassic Jixiqun Chengzihe coal seam, compound coal seam. The coal seam in my mining area development, stable occurrence, the main coal seam. The seam thickness of 2.0m ~ 2.8m. The average thickness of 2.4m. Its direct top is 0.5m ~ 0.7m thick coal shale and shale, the old roof is fine sandstone f = 4,8m ~ 20m, the floor is fine sandstone f = 4.2. Due to the influence of geological structure, some areas are suitable for comprehensive mechanized mining and the rest are suitable for high-grade mechanized mining. 1. Working face conditions: 1.1. Working face geology and mining situation: The face is located in the northern part of a mining area, using long-wall backward mining method, return airway is +40 m level, transport lane is +20 m level, High 20m, working face length 160m,
