特大地下采空区稳定性评价及处理措施

Stability evaluation and dealing approach of the extremely large goaf

本文根据格尔珂金矿采空区的实际情况,提出了采空区的探查方法,稳定性评价方法和处理方法,利用有限元分析方法对采空区进行了稳定性分析,给出两种计算安全厚度的方法,提出了处理空区的基本方法和安全技术管理措施,为合理治理空区和矿山安全生产提供了科学决策依据。

According to the actual condition of the goaf at Geerma gold mine, this paper gives the probe approach, stability evaluation and dealing approach of the goaf. Stability analysis has done in this paper by finite element calculation. This paper also gives two approaches of calculating safety thickness. It brings forth the fundamental approach of dealing with the goaf and safety technology management measure. These offer the scientific guidance to manage the goaf and safety-production of the mine.
