音频电法透视技术在界沟矿井水害防治工作中的应用

Application of Audio Electric Perspective Technology in Mine Water Disaster Prevention and Cure in Jiegou

基于界沟煤矿10#煤层顶底板岩层的地球物理特征,通过现场合理布置测点以及严谨的室内数据处理解析,运用音频电法透视技术探测了10#煤层1021工作面内顶底板低阻率异常区。根据探测结果,结合界沟井田已有的水文地质资料,圈定了1021工作面相对含水区和重点防治水区段。结果表明:音频电法透视技术能够便捷、有效地为矿井水害防治工作提供依据。

Based on the geophysical characteristics of the 10#coal seam roof and floor strata in Jiegou,through on-site reasonable arrangement of measuring points and rigorous indoor data processing and interpretation,the low resistivity anomaly of the 10#coal seam roof and floor in 1021 working face was detected by applying the method of audio frequency electric perspective technique.Ac⁃cording to the results of geophysical exploration,combined with hydrogeological information of Jiegou coal mine,the relative waterbearing areas and key water control sections of 1021 working face were delineated.The results show that audio electric perspective technology can provide basis for mine water disaster prevention and cure conveniently and effectively.
