采用高密度电法在雨季降雨不同时期对运营期矿山山体进行连续监测,研究滑坡地质灾害体的形成规律。首先分析运营期矿山坡体的主要地质组成,对地电物性适用性进行分析,总结矿山坡体各组成地层在降雨期可能发生的地电物性变化,;其次,实时记录降雨不同时期视电阻率的数据累计及电阻率等值线图的变化情况,统计计算视电阻率二维谱的反演成果,推演滑坡体滑面的形成及变化过程,计算滑坡体滑面的规模变化范围及大小,最后利用反演成果对滑坡地质灾害发生的可能性进行判断预警。
The high density electricity method was used to monitor the mines in the operation period continuously during different periods of rainy season rainfall to study the formation regularity of landslide geological disasters. Firstly, the main geologic composition of mine slopes during operation period is analyzed, and the applicability of geophysical properties is analyzed. The geophysical changes of various components of mine slopes during rainfall are summarized. Secondly, the apparent resistivity at different periods of rainfall is recorded in real time The data accumulated and the change of the resistivity contour map were calculated, the inversion results of the apparent resistivity two-dimensional spectrum were statistically calculated, the formation and change process of landslide slip surface were deduced, the scope and size of landslide sliding surface scale was calculated, Finally, the inversion results can be used to judge the possibility of landslide geological disasters.
