Analysis of the Causes of Surface Sand Ridge Collapse in Songxian Mountain Gold Mining Area
The analysis of the causes of the collapse of the surface sand ridges in the Shanjin mining area of Song County shows that the formation of the collapse area is closely related to the distribution of underground goaf,mining methods,fault tectonic activity,and hydrogeological conditions.The formation and filling effect of goaf,stress transfer of surrounding rock,and surface hydrological changes jointly affect surface stability.Suggest conducting in-depth research to optimize mining and filling strategies and reduce the risk of collapse.
