摘　　要：车路山废弃矿山位于淮南市八公山区唐山镇,开采活动对地质和生态环境造成了一定程度的破坏。为消除地质隐患、有利环境保护和土地资源利用,拟规划开展八公山区车路山废弃矿山生态保护修复项目。为查明场地覆盖层厚度、基岩界面起伏情况,于场区北部、中部、南部分别开展了L_(1)线、L_(2)线、L_(3)线高密度电阻率法测量,结果表明:场区浅部覆盖层表现为低阻,电阻率ρ_(s)≤50Ω·m;下伏基岩表现为高阻,ρ_(s)150Ω·m。以ρ_(s)=50Ω·m为分界面划分场区基覆面起伏情况,覆盖层厚度0.3~19.9 m。通过高密度电阻率法为车路山废弃矿山生态保护修复提供了基础勘察资料,也为相似地区开展相关工作提供了思路。The Chelushan abandoned mine is located in Tangshan Town,Bagongshan District,Huainan City,and mining activities have caused a certain degree of damage to the geology and ecological environment.In order to eliminate the geological hazards and facilitate environmental protection and land resource utilization,it is proposed to plan and carry out an ecological protection and restoration project for the Chelushan abandoned mine in Bagongshan District.In order to find out the thickness of the overburden layer and the undulation of the bedrock interface,high-density resistivity measurements were carried out in the northern,central and southern parts of the site,respectively,on the L_(1),L_(2)and L_(3),lines.The results show that:the shallow overburden layer of the site shows low resistance,with a resistivity≤50Ω·m;he underlying bedrock shows high resistance,with a resistivity>150Ω·m;and the undulation of the bedrock interface of the site is divided byρ _(s)=50Ω·m,and the thickness of the overburden layer ranges from 0.3 to 19.9 m.The high-density resistivity method provides basic survey data for the ecological protection and restoration of the abandoned mine in Chelushan,and also provides ideas for similar areas to carry out related work.
