摘要
简述了高密度电阻率法的工作原理。在将高密度电阻率法实际应用于排石场的稳定性评价中时,根据各种装置的特点和T、λ参数对高低电阻率的表征特性,进行了多装置及多参数的探测。通过对各二维反演视电阻率成果图的综合对比和解释,划分出了存在地质隐患的区段。经钻孔验证,效果很好。结果表明通过高密度电阻率法多装置、多参数勘探,可以确定地下介质的电阻率及其电阻率特征,进而对排石场的稳定性做出评价,对同类地质情况的监测、预警,也是行之有效的。
The working principle of the high density resistivity method is introduced. In applying the high density resistivity method to the stability assessment of discharge place, multiple devices and multiple parameter parameters are tested according to the characteristics of various devices and the parameters, T and, which are sensitive to high or low resistivity. The potential geological hazard zones are plotted by aggregate analysis and interpretation of 2-D inverse apparent resistivity figures. The drilling data validate its fine efficiency. The result indicates that the resistivity of underground medium and its characteristics can be confirmed by multi-devices and multi-parameter exploration by use of the high-density resistivity method. The stability of discharge place can be assessed. This method is feasible and effective to monitoring and alert of similar geological conditions.
