摘 要:为解决大阳煤矿采掘衔接紧张的问题,针对大阳煤矿3306工作面轨道顺槽具体工程地质条件,在原有基本支护基础上,采用FLAC3D数值方法分析了不同支护参数对围岩变形的控制效果,进一步优化了现有支护参数。采用优化后的支护参数在3306工作面轨道顺槽进行了工业性试验,试验结果表明,使用优化后的支护方案,巷道两帮收敛量最终稳定在132.6 mm,顶底板移近量最终稳定在226.1 mm,实现了安全快速掘进。In order to solve the problem of the Danyang Mine mining convergence tension,for the specific engineering geological conditions of the 3306 working face,on the basis of the original basic support,the FLAC3D numerical method was used to analyze the effect of different support parameters on the control of the deformation of the surrounding rock,the existing support parameters was optimized.The industrial test was conducted in the 3306 working face with the optimized support parameters,and the test results showed that the convergence amount of the two sides of the roadway was finally stabilized at 132.6 mm and the approximation amount of the top and bottom plate was finally stabilized at 226.1 mm with the optimized support scheme,which realized the safe and rapid mining.
