| 摘 要： | 通过对煤巷两帮煤体受力特点的分析研究,从理论上导出煤体破裂区厚度的计算公式,分析了相关因素对煤体破裂区厚度的影响,与实测破裂区厚度比较,相对误差为10％左右,结果表明,减小巷道高度,增大煤体与岩层接触面的摩擦角是减小煤体破裂区厚度的有效途径。

| Abstract: | By the analysis of load-bearing characteristic of side coal-wall of roadway in seams, the calculation formula of the failure zone width of side coal-wall can be drawn, and all kinds of correlative factors of the failure zone width of side coal-wall can be analyzed. By comparing with the failure zone width of practical test, the relative error is about 10%. It is the effective way to reduce the failure zone width of side coal-wall of roadway in seams by reducing the roadway highness and increasing the rub-angle of roadway in seams. |
