Abstract: The deformation and destruction of river embankment caused by coal mining significantly reduce its flood control safety performance. The traditional treatment method of " first destroy and then treat" has the problems of delayed repair and heavy flood control pressure,which has great potential safety hazards and even induces dam break,flood and other major public safety accidents. The main technical way to solve this problem is to restore the flood control capacity of the river embankment in time while mining. Based on the dynamic process characteristics of mining subsidence,this paper presents the design process of concurrent mining and reclamation of the river embankment in subsidence areas;the calculation model of dynamic fill volume in the process of river embankment treatment is constructed and applied to a treatment project about the river embankment suffered the mining damage. The results show that the risk of river overflow in the process of mining can be reduced, and the damage degree of the river embankment caused by mining damage can be alleviated by using the method of concurrent mining and reclamation to restore the river embankment in the subsidence area;the proposed method of dynamic fill volume prediction can accurately predict the earthwork volume in each treatment stage of embankment treatment,meet the actual engineering needs,and provide a basis for the design of embankment treatment engineering.
