Study on the structural parameters of the mining site using upward drift tailings cemented filling method
The main ore types of Hongniu Copper Mine are siliceous carbonate type,followed by hornblende type.The ore body is produced in a lens like and lotus shaped shape,with sharp extinction and severe branching and recombination.The stability of the western ore body is good,while the stability of the eastern ore body is poor.It is a difficult to mine ore body,especially the KT2-1 thick and large ore body(low grade,large resource reserves).At present,the demand for mineral resources in social production is constantly increasing,This has also brought many new challenges to mining operations.Some shallow mineral deposits have already been exhausted.In order to meet the current social production needs,deep mineral resources and low-grade resources need to be mined,and in some cases,mining recovery is also necessary.In order to improve the efficiency of mining,this article takes the mining operation of Hongniu Mine as an example,explores the application method of upward drift tailings cemented filling mining method in the KT2-1 ore body,and analyzes the key structural parameters of the mining site,aiming to fully leverage the advantages of mining technology and improve the mining efficiency of the deposit.
