Mine geological environment ecological restoration

4. Mine soil environmental problems

Mine soil environment is a hot issue in mine ecological environment monitoring and pollution control. As mentioned above, the problem of mine soil environment mainly refers to the problem of the damage of physical and chemical properties of mining soil under the influence of mining activities. This type of problem is aimed at the duration of mining activities and the possible soil damage caused by mine closure and the damage of mining objects acting on it. Its primary concern is the soil itself, due to the huge impact of soil as a ground object substrate, researchers need to pay special attention to the derivative pollution.

The first thing to consider is the monitoring and evaluation of the soil environment in the mining area, including its ecological interaction objects. Different from the monitoring of ground collapse, researchers mostly monitor the damage of some indicators (leaf area, biomass, etc.) of the ground objects in the mining area in real time through the spectral band through earth observation. In addition, the protection and restoration of soil damage, including the protection and management of its affected objects, is also the focus of its attention.5. Destruction of mine landform and natural landscape

The destruction of landform and natural landscape in mining area is an important problem. The destruction of landform in mining area caused by open pit or well mining needs to be completed by means of restoration. The core problems are soil reconstruction and water system restoration. In addition, the recently emerging problem of landscape evaluation and landscape reconstruction of damaged mining areas is also an important issue. Researchers have begun to pay attention to how to make the ecosystem after ecological restoration and reconstruction of mining areas closer to the natural form of the ecosystem and maintain its resilience.
