富水充填型的采空区会造成极大的工程和环境地质灾害,本文提出了一种类似于漏电现象称之为漏源法,该方法是把常规电法工作中的漏电现象的特征应用于充填有水或其它富水采空区的探测,该方法将充电法与其它方法结合,用以提高对含水充填型的采空区的勘探效果。本文对漏源法的原理作了简要阐述,从理论上导出了独立源和非独立源状态下的电阻率计算公式,对漏源法观测的电阻率特征以及外业工作方法作了较详细的阐述,并以实例验证说明漏源法在查找富水采空区具有很高的可行性,能有效地提高分辨率和探测精度。
A water-filled goaf can cause great engineering and environmental geological disasters. In this paper, a leakage source method similar to the leakage phenomenon is proposed. This method uses the characteristics of the leakage phenomenon in the conventional electrical method In the detection of water-filled or other water-rich goafs, this method incorporates a charging method in combination with other methods to enhance the effectiveness of the exploration for aquifer-containing goafs. In this paper, the principle of the drain-source method is briefly described. The formula for calculating the resistivity of the source-drain and non-independent sources is theoretically derived. The resistivity characteristics observed by the drain-source method and the field work method are more detailed And verified by examples that the source-drain method is highly feasible in finding water-rich gob and can effectively improve the resolution and detection accuracy.
