Abstract

Abstract: The stability analysis model for retained goafs in iron deposit is built based on the organic combination of three zone theory，rock movement theory and finite element theory.Taking a mine in Hebei as an example，qualitative and quantitative analysis were conducted on the stability influence of mine retained goaf to obtain a satisfactory evaluation effect and verify the feasibility of the stability comprehensive analysis method.The results provide a scientific basis for the necessity to treat the mine goafs.

Key words: Iron deposit, Retained goaf, Stability, Comprehensive analysis model
