Description

Technical Field

[0002] At present, the abandoned mines and small mining areas in towns and villages that remain in suburban areas have a small restoration area and a low restoration rate. Land reclamation and greening of abandoned mines is an important measure to ease the contradiction between people and land, rationally utilize land resources, and optimize the ecological environment, which is of great significance. Ecological restoration is the secondary utilization of abandoned mines. The main greening methods for exposed slopes of mines include fish scale pit planting and vegetation trough greening. Fish scale pit planting has uneven greening surface and is not suitable for smooth slopes. The utilization efficiency and economic benefits of reclamation are not high; the greening of vegetation troughs is difficult to construct, and slope weathering and steel corrosion may cause local collapse, which poses a safety hazard. It is not suitable for locations such as roads and houses where human activities are frequent. In view of the above situation, it can be seen that the current ecological restoration needs to solve the problems of low greening rate, unclear greening effect, and low reclamation utilization rate.
