Simple open-pit mine side slope governing and greening method

Abstract

The invention provides a simple open-pit mine side slope governing and greening method. The simple open-pit mine side slope governing and greening method comprises the following steps: S1, stacking cultivation soil on each side slope platform by utilizing existing platforms of an open-pit mine, and allowing the stacked cultivation soil to inclines outwards; S2, sowing grass seeds onto the cultivation soil, synchronously planting seedlings of climbing plants at intervals less than or equal to 1.5 m, and controlling growth directions of the climbing plants in maintenance period so as to arrangethe climbing plants climbing upwards and the climbing plants climbing downwards in a mutually spaced way; S3, laying straw or other dead branches and withered grasses on the cultivation soil; S4, arranging a temporary retaining wall on each of the side slope platform close to an edge; and S5, removing the temporary retaining wall when the greening reaches standard. The simple open-pit mine side slope governing and greening method disclosed by the invention is simple, easy to implement, good in side slope governing and greening effects, free of construction machinery in the whole governance process, little in disturbance to the side slopes, and free of new damages to the side slopes.

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
