矿井音频电透视在矿井工作面探测中的应用

介绍了音频电透视方法的基本原理、工作方法和资料解释,分析了工作面的富水区及分布范围。音频电透视探测的煤层工作面综合视电导率高异常与岩层的裂隙性及其充水程度具有很强的关联性。结果表明,音频电透视探测成果能够综合反映工作面含水情况。通过实例说明音频电透视在工作面富水性探测方面的应用效果。实践证明矿井音频透视技术是该矿探查工作面内部顶、底板内含、导水构造最有效的物探方法。

The Application of Audio Frequency Electric Perspective to Detection of Coal Mine Work Face

This paper introduces the basic principle,operating method and data interpretation of the audio frequency electric perspective.Then it analyzes the characteristics of water capacity zones and distribution.It demonstrates that there exists a strong relationship among abnormal apparent conductivity,crack in rock stratum and the extent of filled water in crack.The study indicates that the detection by audio frequency electric perspective could accurately reflect the water conditions of work face.The case study shows the applied effect of the audio frequency electric perspective in the detection of the watery zones.In short,this technique is a most effective geophysical method for detecting the water-bearing and water-conductive structures in roof and floor within working faces in mines.
