According to a method, firstly, an open-pit mine blasting digital elevation model is constructed, a blasting center is determined based on the open-pit mine digital elevation model, blasting form change spatial distribution is measured, and finally the blasting displacement condition is predicted based on a generalized regression neural network. According to the method, geology related theories and technical methods are used for solving the problem of mine production. The subjects such as geography, geology and mining engineering are organically fused, a prediction model is established based on point cloud data, accurate prediction of the blasting pile displacement after blasting is achieved, the blasting pile displacement serves as ore body displacement to be superposed on the boundary ofan ore body, and secondary delineation of the ore body is achieved. The research progress in the field is promoted, meanwhile, beneficial guidance and help are provided for production of Jiangxi Dexing copper ore, the deplet
