摘要
介绍了对矿区地质构造复杂、煤层赋存不稳定、断层发育等难采煤层的开采情况。在采用旱采采煤方法难以取得好的经济效益情况下，积极采用了水力采煤方法，并取得了较好的技术经济效益。
Because of the unfavourable economic result ofconventional mining systems in working unstableseams featuring complicated geological conditions anddevelopment of faults, hydromining method has beenvigorously applied under these conditions for improvedtechno--economical result.
