Embodiment Construction

[0016] An underground mining method for copper mines. The ore body is divided into upper and lower parts according to the amount of copper metal. The copper content of the upper part is 50%, and the copper content of the lower part is 50%. The upper part of the body is exploited by the in-situ crushing and leaching mining method. During the stage-up mining development, the shaft is dug to the deepest part of the ore body at one time, so that the lowest stage reaches the recovery level. In this way, mining, mining, and development are carried out in an upward stage, and the waste rock produced underground and the tailings of the dressing plant are filled into the goaf in the mining stage of the lower part of the ore body.

[0017] First, the ore body is divided into upper and lower parts according to the amount of copper metal (the copper content of the upper part is 50%, and the copper content of the lower part is 50%), and the dividing line is used as the reference plane. Acc...

Abstract

The invention relates to an underground mining plan used for a copper mine, relating to an exploitation and utilization plan of a copper mine. The invention is characterized in that the mine body is divided into an upper part and a lower part, wherein, the lower part adopts a phase ascending mining while the upper part adopts an in-situ crushing-leaching mining. The plan of the invention can improve a stope stressing state and prevent an earth surface sedimentation and sinking, and the plan is also safe and has low cost, and the resource of a copper mine can be fully exploited and a non-waste exploitation can be realized, thus bringing better economic benefits and social benefit to the copper mine enterprises.

Description

technical field [0001] The invention relates to an underground mining method of copper ore, relating to a development and utilization method of metallic copper ore. Background technique [0002] Copper mining is an important link in the production of copper industry. In the process of copper mining, a large amount of solid waste (waste rock and tailings) will inevitably be produced. The traditional copper mining process requires the construction of waste rock yards and tailings ponds. Waste rock dumps and tailings dams not only occupy a large amount of land, but also seriously damage the natural environment of the mining area. At the same time, many underground copper mines have major safety hazards due to surface subsidence or subsidence due to mining, directly threatening people's lives and property safety. In the process of mining, the determined reasonable mining method is an important factor affecting the benefits of mine investment, and the mining method has a signif...
