Mining technology on mining deep reserves under multi-villages in Wu Tong-zhuang coal mine

There are amounts of deep reserves under multi-village in Wu Tong-zhuang coal mine, affecting seriously coal mine product and development. According to experiences of mining under villages, and considering the specific conditions of Wu Tong-zhuang coal mine, different mining methods under village were thoroughly analyzed through comprehensive economic and technological analysis, then the optimizing project was given. The results show that it is feasible and reasonable to extract deep reserves under multi-village using coordinately-skipped mining technology in this coal mine. Economic and social benefits are very prominent.
