抗动压井壁结构型式的模拟优化研究
摘要:安阳鑫龙矿业有限责任公司根据公司发展规划,对现有矿井进行全面技术改造和矿区扩建,计划在采动影响范围内建设一个新的风井。运用Flac3D数值模拟软件对不同结构形式的井壁(素混凝土、钢筋混凝土、井壁外侧加垫层的复合井壁、井壁内加垫块的复合井壁)进行模拟比较,同时研究不同垫块位置(刚度),进行模拟比较。得出井壁内加垫块的井壁结构较好、垫块位置(刚度)对井壁受力影响较小的结论。
Abstract:Based on the construction of a shaft wall in mining influence area, the different structure types of the shaft wall are numerical simulated by FLAC3D numerical simulation soft. The structure types, includes pure concrete, reinforced concrete, complex shaft wall with added gasket to outside shaft wall and complex shaft wall with added stow-wood to inside shaft wall, are compared with each other. And the influences of stow-woods in different positions and its stiffness are analyzed. The simulation indicates that added stow-wood to inside of shaft wall is better and gasket thickness positions(stiffness) have little effect to shaft wall loaded.
