摘　　要：在借鉴国内外覆岩破坏研究经验和分析新安煤矿水文地质条件基础上,采用FLAC 3D数值模拟、钻孔漏失量监测和井下仰孔并行网络电法CT探测技术对小浪底水库下开采覆岩破坏规律进行了分析,并获得了回归关系式和全煤厚开采导水裂隙带分布预测图,为大型水库下防治水决策提供了科学依据。Based on the previous studies on overlying strata failure law,according to the hydro geologic conditions of Xin＇an coal mine, the overlying strata failure law of coal mining under Xiaolangdi reservoir was analyzed by using methods such as FLAC 3D numerical simulation,seepage observation of drilling fluid and parallel network electric CT detection in the underground upward hole. The regression equation and expectancy map of the water conducted zone in mine area were made. This research provids important parameters and technological support for making water-control decision in the mine area under huge reservoir.
