摘要

应用音频电透视技术,分析了杨村煤矿2702工作面底板30 m和50 m深度界面的探测成果,并与井下水文钻孔揭露的煤层底板岩层结构及探水结果对比研究,发现音频电透视探测的煤层底板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;岩层裂隙与含水层连通性良好部位明显显现视电导率高值异常,结果表明,音频电透视探测成果能够综合反映底板岩层的阻水条件。
By analysing the detection effect of thirty-meter-deep and fifty-meter-deep interface at 2702 working face of Yangcun mine,this paper studied the preventing water condition of coal floor by the audio-frequency electrical penetration(AFEP). According to the structure of terrane and exploring water result of coal floor disclosed by hydrology drill hole,it is demonstrated that there exists strong relationship among abnormal apparent conductivity, crack in rock stratum and the extent of filled water in crack,and there exists obvious abnormal apparent conductivities between crack in rock and the connection place of aquifer.The anslysis indicated that the detection by AFEP could accurately image terrane preventing water condition of the coal floor.
