Retention Goaf Stability Influence Numerical Analysis on Existing Building
In order to study the stability influence of abandoned stope on existing surface constructions,this paper summarizes and analyzes the main controlling factors based upon one mine in Hebei province.This paper also details a qualitative and quantitative analysis utilizing the numerical simulation method.According to the numerical simulation,if the time is taken into account,the current empty stope would also threaten the surface constructions,thus the empty stope should be treated in time.It provides a scientific basis of emphasizing the necessity of treating the empty stope.
