| 摘 要： | 为了确定玉溪矿6m大采高工作面支架的合理支护强度,基于矿井实际地质条件,通过采用经验估算法、基于顶板分类的支护强度计算方法及建立在"支架-围岩"相互作用关系之上的数值模拟分析方法,对工作面支架合理支护强度进行计算,最终确定支架支护强度为1.17MPa,能够完全满足现场需要。研究结果对于大采高支架合理工作阻力的确定具有重要的参考价值。

| Abstract: | In order to obtain rational supporting intensity of 6m large-mining-height face in Yuxi Colliery,this paper applied experience method,roof classification method and numerical simulation method based on mutual relationship of "support-surrounding rock"to calculating rational supporting intensity of powered support on the basis of actual geological condition analysis.1.17MPa was obtained which met actual demand.The result might provide reference for designing working resistance of powered support in large-mining-height face. |
