| 摘 要： | 在阐述回采巷道顶板锚杆组合作用的基础上,给出直接顶范围内岩层分层之间发生离层所必须满足的载荷、跨度、挠度3个条件。在指出锚杆组合作用下组合梁内的岩层组合属于关键分层之间组合的基础上,进一步依据变形协调一致的原则,给出回采巷道顶板端头锚固锚杆支护中锚杆长度、间距、排距、预紧力4个关键支护技术参数的计算公式。该研究对回采巷道顶板锚杆支护设计具有一定的指导意义和参考价值。

| Abstract: | Based on bolt combined effect in the roof of mining roadway, the necessity conditions of load, span and deflection are proposed for stratification separation in the immediate roof. With strata combination of composite beams as key combination and Principle of Deformation coordination, the calculation formulas of the four key Support Technology parameters are obtained for length, spacing, distance between two rows and pretension force in bolt support of the roof of mining roadway. |

| Keywords: | mining roadway bolt composite beams key stratification technical parameters |
