摘要: 建立了将三带理论、岩石移动带理论、有限元理论三者有机结合的铁矿床滞留采空区稳定性分析模型,以河北某矿山为例,对该矿山滞留空区稳定性影响进行了定性、定量分析,取得了较满意的评价效果,验证了稳定性综合分析方法的可行性,同时为矿山进行滞留采空区处理的必要性提供了科学依据。

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
