A Simple Greening Method for Slope Control in Open-pit Mine

Abstract

The invention provides a simple method for greening the side slope of an open-pit mine, comprising the following steps: S1, using the existing platform of the side slope of the open-pit mine, stacking planting soil on each side slope platform, and stacking the planting soil along the outside of the slope Tilt; S2. Sow grass seeds on the planting soil. At the same time, plant seedlings of climbing plants with a spacing of ≤1.5m. The growth direction of climbing plants is controlled during the maintenance period. Plants are arranged at intervals; S3. Lay straw or other dead branches and withered grass on the planting soil; S4. Set up a temporary retaining wall near the edge of each slope platform; S5. Remove the temporary retaining wall after the greening reaches the standard. The method for simple treatment and greening of the open-pit mine slope is simple and easy to implement, low in cost, and has good side slope treatment and greening effect. The whole treatment process does not require construction machinery, has little disturbance to the side slope, and does not cause new damage to the side slope.

Description

technical field [0001] The invention relates to a simple treatment and greening method for slopes of open-pit mines, and belongs to the technical field of slope management and greening of mines. Background technique [0002] From ancient times to the present, human beings have obtained mineral resources from nature in order to survive and develop. Metal deposit mining methods are divided into underground mining, marine mining and open-pit mining. Within the scope of economically reasonable stripping ratio, open-pit mining is preferred, and open-pit mining has received great attention. [0003] While open-pit mining provides us with various mineral resources, it also causes serious damage to the natural environment. Open-pit mining has seriously damaged the mountain structure. Nutrient elements in the soil also flow into gobs or depressions along with fissures and surface runoff, resulting in shortage of soil nutrients in many places and a decrease in soil bearing capacity...

AI Technical Summary

Problems solved by technology

Due to the limited width of the platform, this method limits the space for construction operations; and the slope of the mine is generally high and steep, so the risk factor of building a retaining wall outside the platform is very high, and the construction difficulty is also very high

Moreover, the equipment and materials used in the process of building the retaining wall are not common items in the mining process. Therefore, it is necessary to purchase or lease related equipment, which eventually leads to high cost of greening treatment, complicated process, and difficult realization. Greening The effect of governance is also greatly reduced
