Stability Analysis of Surrounding Rock of Goaf With BackFill Mining Under the Tailings Pond of Waitou Mountain
摘要
Abstract
Taking the ore body mining under the tailings pond of Waitou Mountain as the engineering background,the effects of filling mining and open stope method on the surrounding rock were studied.After the on-site investigation and indoor mechanical test in the mining area,the appropriate rock mechanical parameters are selected,a three-dimensional model is established,and then FLAC3D is used to numerically simulate the displacement change,stress distribution and plastic zone position of the stope during the filling and mining process,and the influence on the surrounding rock is compared and analyzed.The results show that after filling the overlying ore body under the tailings pond after mining,the stress of the stope is redistributed,so that the force of the stope structure is more uniform,which effectively limits the displacement of the stope column,avoids the emergence of pastic zone in the top and bottom plate of the stope,and ensures the stability of the stope and its surrounding rock.This research findings provides technical support and data reference for the mine in solving similar problems.关键词
