摘要 为优化厚煤层大采高工作面巷道支护设计,结合寺河矿6302大采高回采巷道现场实际,采用力学评估、现场抽验、试验分析的方法,对大采高工作面回采巷道地质影响因素进行了研究,得出全新支护方案。通过数值模拟、现场实测对新旧两种支护方案进行分析对比,验证最优支护方案,优化大采高回采巷道支护方案。 In order to optimize the design of roadway support for large mining height working face in thick coal seam,combined with the actual site conditions of the 6302 large mining height mining roadway in Sihe Mine,the methods of mechanical evaluation,spot inspection and experimental analysis are adopted to studies the geological influence factors of mining roadway in large mining height working face,and obtains a new support scheme.Through numerical simulation and field measurement,the new and old supporting schemes are analyzed and compared to verify the optimal supporting scheme and optimize the supporting scheme of large mining height roadway.
