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,ontheL1,L2 and L3 lines.The results show that:the shallow overburden layer of the site shows low resistance,with a resistivity≤50 Ω·m;he underlying bedrock shows high resistance,with a resistivity＞150 Ω·m;and the undulation of the bedrock interface of the site is divided by ρs=50 Ω·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.
