Research on Eco-Governance Technology of Mid and Small-Scale Gangue Heap Without Covering Soil
This study is focused on the mid and small-scale coal gangue heap in a coal mine in Panzhihua City.Rapid restoration technology of slope vegetation without covering soil is proposed,which integrates slope ecological protection,water collection facilities,soil improvement,and vegetation configuration.By u-sing slope treatment technology,soil improvement technology,and plant restoration technology,a restora-tion plan is developed to improve the vertical environmental conditions of the slope and to reduce the im-pact of the gangue heap on the ecological environment.The results show that after 150 days of the applica-tion of the method in the study area,the vegetation coverage has reached more than 95％,the survival rate of plants has reached more than 95％,and the soil erosion rate has been reduced by more than 85％,which significantly improves the restoration effect of the slope vegetation of gangue heap and reduces the impact of the gangue heap on the surrounding ecological environment.This study provides an effective technical means for the ecological restoration of small and medium-sized coal gangue piles without cover-ing soil,which is expected to promote the ecological reconstruction of gangue heap and the benign devel-opment of mine environment.
