Embodiment Construction

[0028] In order to further describe the present invention, the new method of greening the slope of the large-scale open-pit mine of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0029] Depend on image 3 The new method construction scheme sectional schematic diagram of the large-scale open-pit mine side slope covered with green shown in the present invention and combine figure 1 , figure 2 It can be seen that the construction sequence of the new method of greening the large-scale open-pit mine slope of the present invention is: supporting short anchor rod 1 → laying barbed wire 5 → binding and fixing planks 4 → spraying soil 6 → laying and fixing geotextile 7 → maintenance. Specifically, the following processes and steps are adopted:

[0030] 1) Self-made support short anchor rod 1 with a length of 30cm to 40cm. The support short anchor rod 1 adopts Φ10 or Φ12 threaded steel bars; drill ancho...

Abstract

The invention discloses a novel method for plant covering of the side slope of a large strip mine. The following process and steps are adopted that anchor rod installing holes (8) are drilled in the side slope face of the strip mine with the distance of 35-50 cm, and short support anchor rods (1) are rammed into the anchor rod installing holes (8); the side slope face of the strip mine is coveredwith an iron gauze (5); a board (4) is fixedly tied on every two adjacent short support anchor rod support sections (3) at the same level through steel wires; covering earth (6) is sprayed onto the strip mine side slope face in the iron gauze (5); geotechnical cloth (7) is fixedly laid on the outer surface of the iron gauze (5), and thus the short support anchor rods (1), the board (4), the iron gauze (5), the covering earth (6), the geotechnical cloth (7) and the strip mine side slope face form a stable overall structure; and (6), growing-out grass or/and other plants are maintained. According to the novel method, the problems that plant covering of a steep slope of a large strip mine is difficult, high in cost and poor in effect are solved, and environmental benefits, safety benefits andthe visual effect are very significant.

Description

technical field [0001] The invention belongs to the technical field of mine ecological restoration, and specifically relates to a new method for greening on slopes of large-scale open-pit mines. It can effectively prevent the covering soil from being eroded by heavy rain, and at the same time, the green covering of the slope can effectively prevent the weathering of the slope rock mass, and provide the necessary technical conditions for the long-term stability of the slope rock mass in the open-pit mine. Background technique [0002] Slope greening is an emerging ecological slope protection method that can effectively protect exposed slopes, and can effectively realize the restoration and protection of ecological vegetation on slopes. Not only has the function of maintaining water and soil, but also can improve the environment and landscape. [0003] With the continuous expansion of large-scale open-pit mining, the depth of large-scale open-pit mining has also increased rap...
