摘要:
有效探测、准确定位矿井采掘工作面及周围潜在的突水地质构造体，对保证煤矿安全生产意义重大。本文介绍了任楼煤矿及其周边矿井应用瞬变电磁仪、无线电波透视仪、直流电法仪、便携式地质探测仪、地质雷达等矿井物探设备探测采掘巷道及回采工作面周围含(导)水断层、陷落柱等潜在突水构造体所取得的成果。突水构造体的现场实际揭露情况表明矿井物探探测准确率仅达到70%以上，要想实现突水构造体的精确探查，减少钻探工程量，提高探测效率、精度，必须几种物探方法配合使用，才能更准确定性、定位、定量煤矿井下的地质异常体。同时，要想提高探测资料解释的可靠性，必须把物探异常与巷道实际揭露情况进行对比分析，通过已知推测未知，提高物探的反演技术。
Effective detection and accurate location of the coal mining face and the surrounding potential water inrush geological structure, to ensure the safety of coal mine production, is of great signi-ficance. This paper introduces Renlou coal mine and its surrounding mine application instanta-neous change electromagnetic instrument, radio wave penetration instrument, DC electrical prospecting instrument, portable detector of geology, geological radar mining roadway and stope mine geophysical prospecting equipment detection around the face containing (Guide) fault water, subsided column potential water inrush structure results. The actual situation of the water inrush structure shows that the accuracy rate of mine geophysical exploration is more than 70%. It is necessary to improve the detection efficiency and accuracy. At the same time, in order to improve the reliability of the detection data interpretation, we must carry out a comparative analysis of the geophysical anomaly and the actual situation of the roadway.
