摘要
以首山一矿己_(15)-12050工作面实际生产条件为研究对象,采用极限平衡理论分析回采工作面底板垂直应力分布规律。运用FLAC3D数值计算软件研究多次采动影响下,"内错式"和"外错式"布置对底板巷道围岩应力环境、巷道变形的影响。研究结果表明:采用"内错式"布置可以较好地实现巷道围岩的相对稳定。
Limit equilibrium theory was applied to analyzing floor vertical stress distribution rule of mining face based on actual mining condition of 15-12050 Face in Shoushan 1st Mine.The influence of “inner stagger” and “outer stagger” roadway layout manners on stress environment and roadway deformation of floor roadway under multi-mining condition was researched with FLAC 3D soft-ware.Results showed that ＆quot;inner stagger＆quot;manner could realize better stability of surrounding rock.
