Abstract

Abstract: Through the analysis and estimation of stability of goaf of Liaoning Gold Phoenix Gold Mining Industry Co.,Ltd., adopted the method of caving roof surrounding rock of goaf forcedly in small scope, then released to falling slowly to filling goaf, probably happened pressure bump disaster caused by large scale natural caving of 335# goaf was eliminated successfully, underground safe production was assured, provided experience references for similar condition mine.

Key words: Local dilapidating roof by cutting groove, Goaf treatment, Stability analysis
