摘　　要：小庄矿井在煤层开采中遇到了多种地质异常现象,严重影响着煤炭的安全高效开采,为了精细探测该矿存在的地质异常区,以三维地震资料解释为基础,结合巷道掘进的测量数据、写实剖面及补充钻孔数据,开展了地震动态解释技术研究。通过地震地质综合分析,精细解释了矿井煤层中存在的地质异常区、煤层冲刷变薄区、无煤区及沉积缺失区,并分析了各种地质异常成因及影响。该矿井地质异常主要受古地理控制,并由古河道冲刷、差异压实和层间滑动等因素共同作用,矿井采掘资料验证了地震解释的正确性。提出的地震地质综合解释方法,有效地提高了矿井地质异常区探测精度,以此指导巷道设计开发,对小庄矿井煤炭安全高效开采具有重要的意义。The Xiaozhuang mine encountered various geological anomalies during coal seam mining,which seriously affected the safe and efficient extraction of coal.The Xiaozhuang mine encountered various geological anomalies during coal seam mining,which seriously affected the safe and efficient extraction of coal.In order to finely detect the geological anomalies existing in the mine,based on the interpretation of three-dimensional seismic data,combined with the measurement data,realistic profile and supplementary borehole data of roadway excavation,the seismic dynamic interpretation technology was studied.Through the comprehensive analysis of seismic geology,the geological anomaly area,coal seam scouring and thinning area,coal-free area and sedimentary loss area in the mine are explained in detail,and the causes and effects of various geological anomalies are analyzed.The geological anomaly of the mine is mainly controlled by paleogeography,and is affected by the combination of pale channel erosion,differential compaction and interlayer sliding,and the mining data of the mine verifies the correctness of the seismic interpretation.The comprehensive interpretation method of seismic geology proposed can effectively improve the detection accuracy of mine geological anomaly area,so as to guide the design and development of roadway,which is of great significance for the safe and efficient coal mining in Xiaozhuang mine.
