Chinese Abstract

應用音頻電透視技術,分析了楊村煤礦2702工作面底板30m和50m深度界面的探測成果,並與井下水文鑽孔揭露的煤層底板岩層結構及探水結果對比研究,發現音頻電透視探測的煤層底板綜合視電導率高異常與岩層的裂隙性及其充水程度具有很強的關聯性;岩層裂隙與含水層連通性良好部位明顯顯現視電導率高值異常,結果表明,音頻電透視探測成果能夠綜合反映底板岩層的阻水條件。

English Abstract

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.
