摘要
随着煤炭开采强度逐步加大,大量保安煤柱被遗留在采场中,这些煤柱及其上覆岩层组合系统体的稳定性决定了整个采场及覆岩乃至地表的安全,一旦组合系统体发生整体性破坏失稳,将导致许多灾难性后果。为此针对国内外顶板-煤柱组合体在理论模型研究及力学行为上的研究进行了归纳总结与评述,并对组合体稳定性能研究提出了一些新见解。
With the gradual increase of coal mining intensity,a large number of safety coal pillars are left in the stope.The stability of these coal pillars and their overlying strata determines the safety of the whole stope,overlying rock and even the surface.Once the overall failure and instability of the composite system occurs,it will lead to many disastrous consequences.In this paper,the theoretical model research and mechanical behavior of roof pillar combination at home and abroad are summarized and reviewed,and some new opinions on the stability of the combination are proposed.
