从老虎台矿煤层赋存特征、开采方式以及73003#工作面的特殊水文地质特点出发,分析“3.10”透水事故的深层地质原因,排除了上覆采空区积水及断层直接导水造成突水的可能,提出了“离层空间水”形成的机理,为类似工作面的安全回采提供有益参考。
Based on the occurrence characteristics of coal seam, the mining method and the special hydrogeological features of the 73003 # working face, the geological reasons of “3.10 ” seepage accident were analyzed, and the water accumulation in the overlying goaf and the direct water conduction in the fault Resulting in the possibility of water inrush. The mechanism of the formation of water in the “stratified space” is put forward, which provides a useful reference for the safe mining of similar work surfaces.
