摘　　要：通过在保德煤矿81306工作面施工底板测试钻孔,测试回采前后钻孔漏失情况,分析确定回采工作面底板破坏带最大深度,为制定奥灰水防治措施提供基础资料,从而保障矿井安全生产。Through the construction of test drilling in the floor of No.81306 working face of Baode coal mine,the borehole leakage before and after the mining was measured,and the maximum depth of the floor failure zone was determined,which provides the basic data for the establishment of the Ordovician limestone water control measures,so as to ensure the safety of the mine production.
