A method for dynamic reclamation of open-pit mine stope

Abstract

The invention relates to a dynamic reclamation method for an open pit mine stope. According to the technical scheme, the dynamic reclamation method for the open pit mine stope comprises the following steps: after mining of a first step and a second step is finished, sequentially carrying out reclamation on the slope surface (1) of the first step and a lower flat plate (2) of the first step, and carrying out mining stripping propulsion on a lower flat plate (6) of a third step; after mining of the third step is finished, sequentially carrying out reclamation on the slope surface (3) of the second step and a lower flat plate (4) of the second step, and carrying out mining stripping propulsion on a lower flat plate (7) of a fourth step; repeating the process until mining stripping carried out on the last step is finished, sequentially carrying out reclamation on the slope surface of the next-to-last step and a lower flat plate of the next-to-last step, and then carrying out reclamation on the last step. During reclamation, a spray-seeding green technology is adopted, spray-seeding is carried out on the slope surface of a to-be-reclaimed step and the lower flat plate of the to-be-reclaimed step sequentially by adopting spray-seeding equipment (5) on the lower flat plate of the next to-be-reclaimed step, and a non-woven fabric or a straw malt is used for covering after spray-seeding is finished. The dynamic reclamation method for the open pit mine stope has the advantages of high reclamation efficiency, good reclamation effect, short mine ecological environment restoring period and synchronization of reclamation and mining.

Description

technical field [0001] The invention belongs to the technical field of stope dynamic reclamation. Specifically, it relates to a dynamic reclamation method for an open-pit mine stope. technical background [0002] The development of mineral resources is conducive to the development of the national economy, but it will also cause damage to the ecological environment of the mining area and affect the construction of local ecological civilization. Most domestic mines adopt open-pit mining. The layout and construction of dumps, industrial sites, stopes and transportation roads during open-pit mining will cause occupation and damage of land resources in the mining area, especially when the stope stripping operation will directly excavate Damage to the mountain, removal of vegetation, and the exposed rock mass after mining will not only change the original landform of the mining area, but also lay hidden dangers for later disasters such as collapses and landslides. At the same ti...

Problems solved by technology

Therefore, the method of regreening the step and slope of the stope after mining first and using vines to regreen cannot meet the requirements gradually.

[0004] In recent years, with the continuous development of slope reclamation technology, spraying greening technology is gradually used in slope reclamation. It has low reclamation cost and good effect, and many high-efficiency spraying equipment have been developed, especially suitable for steeper slopes. For the reclamation of rocky slopes, if this technology is combined with mining operations, it is possible to realize the dynamic reclamation operation of reclamation while mining in the open-pit stope, but there is no such technical method at present
