Five methods of mine slope treatment and ecological restoration measures

The main content of mine ecological restoration

1. Slope stability and reinforcement

After a long period of over-exploitation, the mine usually has the problem of geological instability and the mountain collapse and other safety hazards. Before the ecological restoration of the mountain, it is necessary to have a comprehensive understanding of the geological environment of the damaged mountain, analyze and demonstrate the risk of various geological disasters, and conduct current status assessment.

Through field survey and mapping, the distribution and scale of the damaged mountain, the susceptibility degree of mining side wall geological disasters, main inducing factors, stability, development and change trend, harm characteristics and so on are found.

According to the geological environment evaluation results, engineering treatment measures are adopted to treat the damaged mountain, such as removing the loose dangerous rock mass and potentially unstable blocks on the slope, cutting the steep slope, and system anchoring to strengthen the slope.

2, mine vegetation restoration

In the process of mine ecological environment restoration, one of the most effective methods is to restore mine vegetation. The key point of this method is to first clarify the goal of mine ecological restoration, and conduct a comprehensive survey of the soil and environmental conditions of the mine, and then determine the method of vegetation planting.

3, mine soil bioremediation

Restoration of soil organisms mainly includes two aspects: On the one hand, restoration of soil microorganisms. The main method is to increase the activity of soil, and then increase the content of organic matter in soil. On the other hand repair soil animals.

A good repair of soil animals can effectively improve soil structure. Soil animals have the ability to decompose dead branches and residual branches, which can not only improve soil fertility, but also help soil plants complete the nutrient cycle.

Mine slope stability control measures

1. Clean the slope carefully

Slope treatment is one of the important contents in mine ecological restoration project. In order to do a good job in slope ecological restoration, the structure and geological condition of mine slope should be clearly defined first, and then the scientific treatment measures for mine slope should be determined. If the mine slope is a relatively loose mixture of soil and rock, it is necessary to clean the dangerous rock on the slope before treatment, and then take slope cutting measures combined with the design requirements to improve the smoothness of the slope.

2. Construct scientific vegetation community structure

In order to improve the vegetation coverage rate of mine slope, suitable vegetation communities can be selected for planting. Since the species of shrub and grass plants are more suitable for growing in slope environment and have the advantages of self-sowing ability, such plants can be selected for planting in mine ecological restoration.

In order to improve the quality of ecological restoration, it is necessary to consider the specific form of mine slope, soil type, weathering condition, development degree of rock fissure and other factors.

3. Set up water interception and drainage facilities

If the mine slope does not do the layout of drainage facilities, surface water or groundwater will flow into the interior along the cracks in the rock mass, which will lead to the internal structure of the mine rock mass being softened and eroded over time, and eventually geological disasters such as landslides and soil erosion.

Therefore, it is necessary to scientifically arrange cut-off water and drain water according to the actual situation of mine slope, and discharge surface water and groundwater timely. After the construction of the drainage ditch, it is necessary to carry out regular maintenance to ensure the smooth drainage.

4, do a good job of project acceptance

In order to ensure the quality of the mine ecological restoration project, it is necessary to standardize the construction process and clarify the construction standards. After the completion of the restoration project, it is necessary to conduct quality inspection and acceptance of each restoration link. The quality inspection and acceptance department shall strictly carry out the inspection and acceptance in accordance with the standards stipulated in the ecological restoration project, and especially strengthen the quality inspection and acceptance of concealed projects and sub-projects. In order to promote the mine can really restore the ecological function.

5, do a good job of slope monitoring

The slope monitoring should be strengthened by means of science and technology. Traditional slope monitoring requires long-term manual measurement, low efficiency, high cost and large error, but the use of modern advanced technology for slope monitoring has many advantages, such as flexible selection, less restricted by terrain and other conditions, high degree of automation, real-time dynamic monitoring and so on.
