通过对回采巷道常用的几种支护方式采用数值方法,对薄煤层回采巷道不同支护形式下巷道围岩应力分布、位移分布等情况进行数值模拟,研究分析不同支护方式的作用机理及其控制围岩变形的作用,选择出最适合薄煤层回采巷道快速掘进的支护方式,及其合理支护参数,进而指导现场施工。
Through several numerical methods commonly used in the mining roadway, the numerical simulation is carried out on the stress distribution and displacement distribution of the surrounding rock under the different support patterns in the mining laneway with thin coal seams. The mechanism and the mechanism of the different support patterns are analyzed Control the deformation of surrounding rock and select the most suitable support method for rapid excavation of thin seam mining roadway and its reasonable support parameters to guide the construction on site.
