In order to find out the damage condition and damage degree in Anshan mining area, through the investigation of all mining enterprises in Anshan City, this paper analyzes different kinds damage area of mine sites, the water and soil loss condition of the damaged land and the damage to the ecological environment of the damaged land in Anshan mining area. The investigation results show that the average unit damage area of Anshan mining area is 22.63hm2, the field and tailing pond are the most serious areas of soil erosion, and they are the key areas of ecological reconstruction of damaged land in mining area. The intensity of water and soil loss in the mining area is large, water erosion silts up the downstream river reservoir, increases flood and waterlogging disasters, pollutes water quality, blocks out the sun with wind erosion and dust, making it difficult to recover; the recovery and control rate is low; it harms the health of the people. And put forward the corresponding restoration measures and suggestions, cut the slope for the slope with large gradient, and backfill the gravel to the low-lying place; use the method of soil consolidation to repair the damaged land in the mining area; increase the vegetation coverage through afforestation, to prevent sand and soil consolidation and reduce water and soil loss; at the same time, establish the corresponding drainage and storage system, and take the necessary anti slide and anti-collapse measures Physical and chemical remediation technology is used to adjust the content of harmful substances (nitrogen, phosphorus, potassium, etc.) in the soil, so that the vegetation in the mining area can grow better.
