摘要
以七岭煤业综采工作面回采巷道为例,采用FLAC3D数值模拟软件,分别对工作面回采巷道掘进期间巷道围岩屈服破坏特征、巷道围岩垂直应力、巷道围岩位移特征进行分析,得出坚硬顶板条件下回采巷道最优的支护方式和支护参数,并且成功的应用于工程实践。
Taking fully mechanized working face mining gateway of Qiling Coal Industry as an example,the paper uses FLAC3D numerical software to analyze the yield failure characteristics of surrounding rock,the vertical surrounding rock stress and the roadway surrounding rock displacement characteristics respectively during tunneling,it concludes the best gateway support way and supporting parameters under the condition of the hard roof,and they are applied to the engineering practice successfully.
