The radio-wave penetration method can detect the relative locations of abnormal structures such as collapse columns,faults and thin coal layer areas,and the mine transient electromagnetic method can estimate the water-containing situation of these structures based on the variation of the resistivity in the detection range.
提出了探测煤矿陷落柱位置及其富水性的综合矿井物探技术:采用无线电波透视法可确定煤层内异常构造的相对位置,利用矿井瞬变电磁法可根据电阻率的变化来查明探测范围内异常构造的富水情况。
Radio-wave penetration method is mainly applied to detect the abnormity structures(collapse column, fault and thin coal layer area etc),and this paper puts emphases on introducing the use of the radio-wave penetration method in exploring the crytic hydrated structure in coal layer.
无线电波透视法主要应用于探测煤层内异常构造(如陷落柱、断层、煤层变薄区等),本文则重点介绍了无线电波透视法在探测煤层内隐伏导、含水构造异常的应用情况。
