摘　　要：在准确认识松散层三含的富水性和薄煤层覆岩破坏规律的基础上,评价了三含对工作面的充水影响,论证了杨村煤矿二采区薄煤层留设防砂煤柱开采的可行性,成功实现安全回采。把杨村煤矿薄煤层的防水煤岩柱高度从原来的30m缩小到10.42m,解放水体压煤6.38M t。Based on the exact understanding of water abundance in the 3^rd unconsolidated aquifer and the rule of overlying strata damage in thin seam, the influence of water inrush on working face is estimated, the feasibility of retaining sand-proof pillar mining in the 2^nd mining area in Yangchun Colliery is demonstrated and the safety mining is realized successfully. The height of sand-proof pillar of Yangchun Colliery in thin seam is reduced from 30m to 10. 42m and 6. 38Mt coal under water body is able to be mined now.
