Abstract:Aiming at the 500 m level complex and difficult mining ore body in the west area of the main ore body of a copper mine, three feasible mining schemes are put forward, which are I. the upward drift layered filling mining method, II. low sublevel, open stopping, and small step back-filling method with inside the ore vein drilling ore drawing roadway, and III. low sublevel open stopping small step back-filling method with outside the ore vein drilling ore drawing roadway. The stope layout, mining and cutting engineering and mining technology of the three mining methods are introduced in detail. Through the comparison of advantages and disadvantages of mining methods and technical-economical indicators, the upward horizontal drift layered filling mining method is selected for mining. This mining method adopts shallow hole blasting in the process of mining, which can better protect the unstable sand-bearing layer on the hanging wall, and the safety of the working environment is high. In addition, the mining cut ratio and dilution loss are relatively lower, and the ore removal grade is high, so the comprehensive benefit is obvious.
