In order to solve the prominent contradiction between the ultra-large-scale coal resource mining and fragile ecological environmental protection,the ecological environment management of the underground mine in Shendong mining area was taken as the research object,and the damage to the ecological environment caused by coal mining in Shendong mining area under high-intensity mining conditions was studied.The concept of the comprehensive three-dimensional ecological environment in the above and below the mines is proposed,including the underground ecological environment in coal mines,the surface ecological environment and the atmospheric ecological environment in the mining area,the ecological environment management technology above and below the mines has been developed and successfully applied in the Shendong mining area.The results show that:A good underground coal mine ecological environment can be built by comprehensive treatment of underground coal mine ventilation,gas,dust,goaf coal,water resources,gangue,etc;Utilizing the self-recovery ability of the surface ecosystem,and supplemented by artificial measures to gradually restore the damaged ecosystem or make the ecosystem develop in a virtuous cycle,to create a pleasant surface ecological environment;To control the outbound dust,boiler flue gas,and gas extraction from washing and loading trucks to create a suitable atmospheric ecological environment in mining areas.
