A slope protection device and method for an open-pit mine dump

Abstract

The invention discloses a slope protection device for an open-pit mine dump site, which comprises a plurality of protective nets with criss-cross connection nodes and T-shaped protective bars arranged at the positions of the criss-cross connection nodes of the protection nets; wherein, the The T-shaped protective rod includes: a fixed shell, an internally threaded ring, an axially inclined block, a radially inclined block and an operating rod; the threaded section of the operating rod is threadedly connected with the internally threaded ring and drives the internally threaded ring along the axial direction of the fixed shell move, and then push the axial inclined block and the radial inclined block to slide in turn; the side wall of the fixed shell is filled with a liquid component that can foam and cross-link polymerization when it encounters water. The slope protection device of the present invention is convenient and quick to operate, not only can monitor the loosening of the slope of the dump, but also can effectively prevent the occurrence of landslides on the slope of the dump, and meets the use requirements for the stability of the slope of the dump in the open-pit mine. The invention also discloses a slope protection method for the open-pit mine dump.

Description

technical field [0001] The invention relates to the technical field of side slope treatment in mining areas, in particular to a slope protection device and method for an open-pit mine dump. Background technique [0002] With the continuous expansion of the scale of open-pit mines and the increase of output, the slope control of open-pit mines has become a top priority. Under the influence of long-term weathering, rain erosion, complex geological conditions and other comprehensive factors, open-pit mines are prone to landslides and step instability, which seriously threaten the safety of open-pit mine production, especially in open-pit mine dumps. Under the influence of complex environmental factors, safety accidents are extremely prone to occur. [0003] There are many methods for controlling landslides in open-pit mine slopes, and the common main methods include anti-slide engineering, drainage engineering, anti-scour slope protection, soil improvement, etc. In the specif...
