- Word: Rehabilitation Engineering
- Explanation: This includes leveling excavated pits, coal gangues, waste rock piles, rebuilding soil layers, and planting crops; using reduced steep slopes and covering the ground with vegetation to prevent erosion and reduce leaching of harmful minerals To a minimum. Rehabilitation works should be planned before surface mining. For example, the topsoil layer of the area to be mined in the open air should be stripped off and stored properly. After mining, first backfill the crushed stone, vermiculite, etc. After the pit is basically filled, then cover the topsoil. After planting a few crops of alfalfa or similar crops on it, the soil minerals and organic matter can be fully restored, and Plant other crops. Quarry or gravel pit, because the rock does not contain sulfide or other harmful substances, the pit can be filled with water for artificial lakes, fish ponds or swimming pools. Rehabilitation works are expensive and generally not easy to do. However, some countries have stipulated in mining laws that this must be done, and the results have proved that the cost is cheaper than the cost of environmental damage. [1]
