Mine ecological restoration system for accelerating vegetation restoration

Abstract

The invention provides a mine ecological restoration system capable of accelerating vegetation restoration. The system comprises plastic cloth, fixing units, greening units and repairing units; the plastic cloth is laid along a mine slope at equal intervals, the side edges of the adjacent plastic cloth are stacked together, and a new soil layer is laid on the surface of the plastic cloth; the fixing units are installed at the positions where the adjacent plastic cloth is stacked at equal intervals, and reinforcing and limiting units, sampling units and sulfate reducing bacteria supplementing units are sequentially and alternately installed on the fixing units which are arranged at equal intervals; the greening units are mounted on the surface of the new soil layer; the repairing units are installed on the surface of the mine slope and located on the lower side of the plastic cloth. The sampling units can regularly sample an acid soil layer of a mine and detect and observe internal restoration changes of the acid soil layer, sulfate reducing bacteria can be added according to needs through the sulfate reducing bacteria supplementing units, stable ecological restoration is guaranteed, the greening units can prevent wind and fix sand and are beneficial to plant planting, the repairing units can be used for repairing the acid heavy metal soil layer of the mine.

Description

technical field [0001] This application relates to the field of mine eco-environmental protection, specifically, a mine ecological restoration system for accelerating vegetation recovery. Background technique [0002] At present, the ore deposit is composed of ore and wall rock, and the mining of ore needs to strip the wall rock, because the peeling of the wall rock changes the original geological environment, so that a large number of sulfides with stable reducing environment are exposed to the oxidizing environment, due to chemical oxidation and Biological oxidation will produce severe acid mine drainage, seriously affecting the ecological environment of the mine, and it is very difficult to restore the mine ecology after mining; [0003] At present, in order to overcome the impact of acid drainage on the environment, the surface of the mine is usually paved first, and then neutralized with lime, or covered with a new soil layer.

Problems solved by technology

[0002] At present, the ore deposit is composed of ore and wall rock, and the mining of ore needs to strip the wall rock, because the peeling of the wall rock changes the original geological environment, so that a large number of sulfides with stable reducing environment are exposed to the oxidizing environment, due to chemical oxidation and Biological oxidation will produce severe acid mine drainage, seriously affecting the ecological environment of the mine, and it is very difficult to restore the mine ecology after mining;

[0003] At present, in order to overcome the impact of acid drainage on the environment, the surface of the mine is usually paved first, and then neutralized with lime, or covered with a new soil layer. The above repair methods are relatively extensive, and it is easy to bring out acidification after rainwater seeps into the mine surface. Drainage, ecological restoration is slow and the effect is poor
