Research on Pollution Biological Control Strategy of Rich Sulfide Mining Wasteland
[Objective]The biological control strategies for AMD pollution based on manual intervention is discussed to provide solutions for pollution remediation in similar mines.[Method]Through long-term tracking research on the practice of ecological reclamation engineering in mines,combined with the"closed-loop"reaction conditions generated by AMD,the evolution law of its pollution and pollution biological control strategies based on manual intervention were analyzed.[Result]The results show that the process of AMD pollution evolution and artificial intervention restoration is mainly divided into five stages:pollution incubation period,severe pollution period,engineering restoration period,vegetation restoration window period,and continuous deterioration period.The key to biological control of mines potential pollution is to persist in dynamic governance and timely reclamation and greening during the pollution incubation period.During periods of severe pollution,rapid restoration of existing pollution and comprehensive reconstruction of the soil environment through engineering measures are key to the recovery of vegetation.However,rapid reconstruction of vegetation community systems within the window period of vegetation restoration to enhance soil function restoration is key to curbing incremental pollution and ensuring sustainable recovery of vegetation systems.[Conclusion]Using biological strategies to control mining pollution has a higher cost-effectiveness ratio,and it's sustainable,and environmentally friendly.
