摘要 采用地面瞬变电磁法对拟建搬迁安置小区是否存在煤矿采空区进行勘查,运用未充水采空区、充水采空区分别在视电阻率断面图上呈现相对高阻、低阻异常的地球物理标志,结合地面地质灾害调查成果,较为准确的确定了彬州市某煤矿采空区具体位置,并推断塌陷过渡带范围。 Application of ground transient electromagnetic method to a proposed relocation and resettlement area is adopted for checking whether goaves of coal mine exist underground.Combined with the results of ground geological hazard survey,accurate determination of the mined-out area of coal mines and deduction of the range of collapsed transition zones in Binzhou City have been made by using relatively high and/or low resistance abnormal present on apparent resistivity profiles by no water-filled and water-filled goaves as the geophysical indicators.
