摘要:
通过对唐口煤矿深部高应力软岩巷道的FLAC 3D数值模拟,揭示了深部高应力软岩巷道开挖后的围岩应力场、位移场及塑性区的演化规律; 提出了锚注联合支护技术,对比研究了3种支护方式的支护效果,并在施工过程中通过现场监测及时反馈监测信息进行支护方案及参数优化设计。工程实践表明,锚注联合支护技术能够较好地控制深部高应力软岩巷道围岩的大变形、强流变和底臌。
Abstract:
Through numerical simulation research with FLAC 3D of deep soft rock roadway under high stress in Tangkou Coal Mine, the evolution regularity of stress field, displacement field and plastic zone are revealed. The bolting-grouting combined support technique is proposed, and the supporting effect of three supporting method to verify the anchor note combination supporting rationality is comparatively studied, then the support scheme and parameter optimization design is carried out in construction process with the timely field monitoring information feedback.Engineering practices indicate that, bolting-grouting combined support can well control the large deformation, strong rheologic and bottom heave of deep soft-rock roadway under high stress.
