Abstract_FL In view of the large-scale and efficient coal mining in ecologically fragile areas,which causes a large scope,long cycle and high intensity of ecological impacts,and the lack of a systematic technology that integrates the whole cycle of mining,source reduction and ecological elements,which leads to high costs,low efficiency and poor results in the ecological restoration of mining areas.This paper puts forward the concept of ecological protection coal mining,the damage conduction pathway of surface mining and the damage conduction model of shaft mining,the quantitative analysis method of ecological damage and the decision-making method of ecological restoration in mining areas.It has developed land-saving and loss-reducing mining for open pit mines,ecological stratigraphic reconstruction,distrib-uted water resources collection,storage and use,and synergistic restoration technologies based on the"ecological restoration window peri-od".It has researched and developed technologies for damage conduction control in well mining,ecological function restoration of aquifers,construction of assembled wedge-shaped groundwater reservoir dams,and ecological restoration of subsidence zones in time zones.An ecologically protected open pit mining demonstration project has been completed in the mengdong mining area,with the vegeta-tion cover in the baorixile open pit mine demonstration area increasing from 30%to 59%of the pre-exploitation area,and that in the shengli open pit mine demonstration area from 5%to 39%of the pre-exploitation area.A demonstration project for ecologically protected coal mining in the shengdong wells has been completed,with vegetation cover increasing from less than 10%to 70%of the pre-exploita-tion area.The research results provide scientific and technological support for eco-protective coal mining and have wide application and promotion value.
