采场暴露空间安全性分析法的研究与应用

The research and application of safety evaluation method on the mined-out area

本文利用Burgers-Coulomb模型,对采空区岩体逐渐破坏的机理进行了分析研究。在此基础上,推导并建立了采场安全评价的一种新方法—采空区安全性分析法,并将该方法应用于云锡松矿芦塘坝10-6矿体开采的安全评价,收到了良好的效果。

In this paper, the authors analyse the mechanism of rock deformation, displacement and falling around an opening with time by Burgers-Coulomb model. Then a safety evaluation method is setup. An example is given of applying the method to mining 10-6 ore body Yunnan Tin Corporation.
