Greening method and structure for high and steep rock slope of surface mine

Abstract

The invention provides a greening method and structure for a high and steep rock slope of a surface mine. A soil layer covering layer with a certain thickness can be formed through backfilling, and thus the soil discharging work amount of the covering layer is reduced; meanwhile, through the mode that a net-shaped geomembrane is laid inside and a plurality of long anchor rods and short anchor rods are additionally arranged, the slope body sliding face can be effectively prevented from being generated, and the safety of the interior of a slope body of the high and steep slope with the angle being 65 degrees or above is guaranteed; meanwhile, a soil matrix (planting soil backfilling area) has the enough thickness, and a reinforcing mesh and turf form protection on the outer layer, so that the situation that a water and soil loss site is generated due to the fact that the soil matrix is prone to being washed by rainwater is avoided; for some water-deficient areas, due to the existence of the net-shaped geomembrane, water retention of a certain degree can be achieved, thus the survival rate of vegetation is increased, and the re-greening effect is greatly enhanced; and through the slope protection measure that the reinforcing mesh is combined with the long anchor rods and the short anchor rods, the integrity of the high and steep slope with the angle being 65 degrees or above can also be guaranteed.

Description

technical field [0001] The invention relates to a greening method and structure of a high and steep rocky slope in an open-pit mine, which is suitable for the greening design of the rocky slope after mining in the open-pit mine. Background technique [0002] At present, in the slope greening project of open-pit mines, for the gentle slope or low steep slope below 60°, the existing slope protection technology has been able to better achieve the effect of support and regreening. However, for steep rocky slopes with a slope greater than 60°, the conventional thick-layer base material spraying and regreening method is generally used. The above method is prone to rainwater erosion, which will cause the substrate to peel off and the barbed wire hanging on the surface to be exposed, resulting in the effect of ecological governance and regreening. poor. Some projects adopt the method of regreening by spraying with high-grade aggregates to regreen the slope, but the above regreening...

Problems solved by technology

Some open-pit mines can take advantage of their location advantages to realize the sale and disposal of the stripped layer, but for most open-pit mines, the above-mentioned stripped layer needs to be set up separately for dumping, without using land-saving
