| 摘 要： | 本文对地下采矿中遇到的煤岩柱及顶板进行了力学的简化处理;从突变理论出发,引用煤岩损伤本构方程,讨论了煤(岩)柱失稳的物理机制,并给出了煤(岩)柱失稳的条件。从这种观点出发可得到比其它方法更丰富的结果,这种结果可为现场采矿设计提供依据。

| Abstract: | This paper provides a simplified mechanical treatment for coal / rock pillar and roof in underground mining. From the cataestrophic theory, applying related equations, this paper discusses on physical mechanism of unstable coal / rock pillar, and the conditions of the unstability are also given. From such a point of riew, the obtained results will be richer than from other methods and can provides basis for mining designing. |
