摘要
在合理布置钻孔位置和充分了解区域地质构造以及矿区地层岩性的条件下,应用Midas/GTS对典型危害与治理断面进行数值模拟。分析采空区开挖形成过程中的应力应变原理;论证道路荷载长期作用下采空区稳定性加剧失稳,总结倾斜煤层采空区注浆治理效果。
Decorate in the reasonable drilling structure and mining under the condition of position and fully understand the regional geological formation lithology, using Midas/GTS for numerical simulation of typical hazards and governance. Formed in the process of stress and strain analysis of mined-out area excavation principle, argument road load under the action of long-term stability of mined-out area intensified instability, conclusion seam goaf grouting treatment effect.
