摘　　要：采用高密度电阻率法对矿山边坡局部地段进行勘探调查,找寻影响矿山稳定性的隐伏断层及岩性软弱层,并针对于基岩裸露的特殊地表,对高密度电法的采集装置进行了改良。综合相关地质资料分析验证,本次勘探取得了较好的效果,为该边坡的稳定性计算与分析评价以及后续相关治理措施提供了可靠的地质依据,证明了高密度电法对于矿山边坡不良地质体的勘探具有良好的效果。同时本次研究也验证了改良装置的准确性以及该装置在克服地表高阻体影响与提高野外工作效率等方面的优越性,该装置可以推广到其他诸如城市公路等类似基岩裸露地表的工区使用。The high density resistivity method is used to explore and investigate the local area of mine slope to find the hidden fault and lithologic weak layer which may affect the stability of mine. Considering the special exposed bedrock surface, the collecting device of high density resistivity method is improved. Based on the analysis and verification of related geological data, the exploration has achieved good results, thus providing reliable geological basis for the slope stability calculation, analysis and evaluation as well as subsequent related management measures. In addition, the exploration also has proved that the high density resistivity method is of good effects in the exploration of unfavorable geologic bodies of mine slope. Meanwhile, this research also has verified the accuracy of improved device and that the device is advantageous to overcome the influence of high resistivity body on the surface and improve the field work efficiency. The device can be applied to other work areas similar to the bedrock exposed surface, such as urban road.
