Slope protection device for strip mine dump and method thereof

Abstract

The invention discloses a slope protection device for a strip mine dump. The slope protection device comprises a plurality of protective nets and T-shaped protective rods, wherein the protective nets are connected in a criss-cross mode, and the T-shaped protective rods are arranged at the criss-cross connecting joints of the protective nets. Each T-shaped protective rod comprises a fixing shell, an internal thread circular ring, an axial inclined block, a radial inclined block, and an operating rod; the threaded section of the operating rod is in threaded connection with the internal thread circular ring and drives the internal thread circular ring to move in the axial direction of the fixing shell so as to sequentially push the axial inclined block and the radial inclined block to slide; and the side wall of the fixing shell is filled with a liquid component which can be foamed and subjected to cross-linking polymerization reaction when encountering water. The slope protection device is convenient and fast to operate, the loosening condition of a side slope of the mine dump can be monitored, the landslide phenomenon of the side slope of the mine dump can be effectively prevented, and the use requirement for stability of the side slope of the strip mine dump is met. The invention further discloses a slope protection method for the strip 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...
