Slope Surface Treatment Method of Mine Dump

Abstract

The invention discloses a slope surface treatment method of a mine waste dump. The slope surface treatment method comprises the following steps that a slope surface A of the mine waste dump is trimmeduntil the overall slope is less than 60 degrees; multiple rows of arc-shaped steps with middles upward arched are sequentially excavated in the slope surface A of the mine waste dump from the slope top to the slope bottom, and at least one arc-shaped accommodating groove is excavated in a table top of the uppermost arc-shaped step I close to the slope top in the length direction of the arc-shapedstep I; corn straw or reed straw after soaking and rolling is paved on the bottoms of the arc-shaped accommodating grooves to form straw layers; cultivating sheet bodies are sequentially paved from the arc-shaped step N close to the slope bottom to the arc-shaped step I at the slope top; and shrubs are transplanted on the table tops of the two ends of the multiple arc-shaped accommodating grooves. According to the slope surface treatment method, the vegetation coverage of the mine waste dump can be quickly restored, the water and soil are effectively conserved, the occurrence of natural disasters is avoided, and certain leaching treatment can be conducted on the heavy metal contaminated soil.

Description

technical field [0001] The invention relates to the technical field of water and soil conservation and ecological restoration, in particular to a slope treatment method for a mine dump. Background technique [0002] The development and utilization of mine mineral resources has effectively promoted the development of the national and local economy and society, but a large amount of spoil is produced in the process of mineral resource development, and a series of large-scale dumps are formed. Loss is a prominent ecological and environmental problem in the process of mineral resource development and construction. In addition, because the mine spoil contains a lot of gravel, its water holding capacity is poor, and its nutrient content is low. Although the soil of the spoil platform is mechanically compacted, the slope soil is loose and lacks the cohesion between natural soil particles. Poor erosion and anti-scourability; the spoil is artificially piled up, with large height dif...

Problems solved by technology

For a long time, due to the lack of effective governance responsibility system and vegetation restoration model, the above-mentioned serious soil erosion, geological disasters and other ecological and environmental problems have occurred, and soil pollution and water pollution have been caused, affecting the social stability around the mine and the local people. normal production and life and physical health, etc.
