Fast spoil disposal slope protection and ecological recovery open-pit mining technology

Abstract

The present invention relates to an open-pit mine excavation process, in particular, it relates to an open-pit mining process capable of quickly discharging earth to protect bank and making ecological restoration. It is characterized by that in one end of open-pit mine or its middle said invention adopts a conventional method, if the stripping and mining operation of initial stripping working face is completed, on the deposit mining direction the mining working face can be divided into left side zone, medium zone and right side zone, then they are further divided into several smaller subsections, every subsection can be used as an unit, on every subsection the processes of stripping, mining, backfilling and banking, cultivating-greening or covering with concrete are progressively adopted so as to implement the invented open-pit mining process.

Description

technical field [0001] The invention relates to an open-pit mining process for mineral resources. Background technique [0002] So far, several important links such as waste rock stripping, waste rock transportation and discharge, waste rock field reclamation and greening, and slope maintenance in the open-pit mining process at home and abroad are relatively independent, and independent design and construction And management, the guiding ideology is to meet the production capacity requirements between the upper and lower process links and save costs. [0003] Usually open-pit mining is continuously advanced from one end to the other, resulting in a large range of rock and soil disturbance and ground environment damage. The final slope formed during the mining process may exist for several years or even decades, and a large number of slopes need to be completed Maintenance work consumes a lot of money, and engineering geological disasters such as landslides may also occur, w...

Problems solved by technology

[0003] Usually open-pit mining is continuously advanced from one end to the other, resulting in a large range of rock and soil disturbance and ground environment damage. The final slope formed during the mining process may exist for several years or even decades, and a large number of slopes need to be completed Maintenance work consumes a lot of money, and engineering geological disasters such as landslides may occur, which will cause losses to people's lives and property

For mines with waste rock internal discharge conditions, waste rock discharge is generally carried out in the pit. This discharge is mainly to consider saving waste rock transportation costs, and does not combine it with the timely, complete and final treatment of the final slope.
