利用漏源法探查富水采空区

Use Leakage Source to Prospect Cavern with Water

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。

The cavern with water coursed by mining poses potential geological hazards to engineering and environment. A method named as leakage source of electricity is proposed to prospect the cavern with water coursed by mining in this paper. This method can combine the ＂raise - a - la - masse＂ method with other methods to raise the effect of prospecting the cavern filled with water. The principle of the method is simply demonstrated. The results of application of the method show that leakage source of electricity is of high feasibility in the prospecting of the cavern with water coursed by mining and can improve the resolution and precision of exploration of cavern with water.
