Xinli mining area of Sanshandao gold mine is the only undersea metal mines in China，its mining technology demand is higher，and also have serious security problems.At present，at home and abroad，the research on the prediction of rock mass movement and surface subsidence caused by coal mining is relatively mature，and a variety of practical subsidence models and realistic surface subsidence prediction methods are formed.However，most large and medium metal mines are mined using filling methods.The effect of repeated mining not only makes the mines face new deformation and damage of the filling body，and with the continuous expansion of the scale of the filling body，the large-scale deformation and destruction of the filling body further complicates the movement of rock mass.Finally，threatening the safe production of mines.With the popularization of filling mining methods，the law of rock mass movement and surface deformation caused by filling mining has become an urgent problem to be solved.The in-depth study of this problem can provide the basis for rock movement and surface settlement for the safe mining design of submarine mines，and provide a conceptual model for the prediction of rock mass movement and surface settlement caused by mining.So，grasping mining-induced movement rules of overburden above goaf and realizing valid predictions for overburden movement are the problems to be solved for Xinli seabed gold mine.The monitoring of the displacement of rock mass is a direct means to study the movement and deformation of rock mass caused by inclined orebody mining.The movement and deformation characteristics of inclined overburden in mining by filling method are obtained by monitoring the displacement of roof of each level of the 55 lines underground in Xinli mining area.On this basis，the paper firstly proposed a cantilever mechanism to explain movement and deformation in overburden rocks triggered by cut and fill mining method in metal mines with inclined veins.Based on the analysis of the displacement monitoring data of roof，and according to the characteristics of the displacement curve，the profile functions method is proposed to predict the subsidence of inclined overburden in mining by filling method.The method consists of several exponential functions and the subsidence curve obtained by this method is very close to the measured results.And the accuracy of the prediction is all above 85%.Therefore，the research results have important guiding significance for the safe production of submarine mines.
