石膏矿采空区长期稳定性演变机制及破坏模式
|
摘要
在分析国内外有关采空区长期稳定性研究成果基础上,提出了石膏矿采空区长期稳定性受流变及开采爆破造成的扰动影响较大,并通过实验证明爆破扰动造成石膏矿采空区"顶板-矿柱-底板"支撑体系岩石在常规应力状态下损伤明显,认为爆破扰动损伤是导致采空区动态失稳的重要原因,为采空区长期稳定研究与管理提供了新的途径。
On the basis of analysis on long-term stability of goaf at home and abroad,it is put forward that long-term stability of goaf in gypsum mines is obviously influenced by the disturbance caused by rheological and mining blasting.Experiments proved that the rock in the support system of gypsum mine roof-pillar–floor system of gypsum goaf under normal stress is obviously damaged by the blasting disturbance.Blasting disturbance damage is an important reason that leads to the dynamic instability of goaf,providing a new way for research and control of long-term stability of the goaf.
