摘要
为了确定清河门矿231采区3-3煤层上行开采的可行性,利用相似材料模拟方法分析了下部3-2煤层开采对3-3煤层的影响,在此通过布置巷道和钻孔进行现场探测,分析了3-3煤层下伏采空区的充实程度、3-3煤层下沉变形及围岩采动裂隙、顶板离层状态等情况。在此基础上,成功对231采区3-3煤层N3路的近距离煤层实行上行综合机械化开采。
In order to determine the overmining possibility of the 3-3 coal seam of 231 mining area in Qinghemen mine, analyse the impact of 3-2coal seam to 3-3 coal seam by similar material simulation. Aanalysising the substantial degree in goafunder the 3-3 coal seam, the degree of deformation in subsidence and fractured rock on mining and the roof separation state of 3-3 coal seam. On this basis, successful exploitation of the comprehensive mechanization of overmining on the N3 road 3-3 coal seam of 231 coal mining area.
