摘要
聚焦于特厚煤层回采巷道煤柱宽度及围岩控制的研究,旨在解决特厚煤层回采工程中的安全性和稳定性问题.通过分析特厚煤层回采的重要性和挑战,深入探讨合理煤柱宽度选取以及围岩控制策略,提高矿山生产效率与安全性.并分析特厚煤层特点、回采方法和技术现状,综合分析煤柱宽度与围岩控制的关系,为相关领域提供有效的指导.
Abstract
This paper focused on the study of the width of coal pillars and surrounding rock control in the mining roadway of extra-thick coal seams,aiming to solve the safety and stability issues in the mining engineering of extra-thick coal seams.By analyzing the importance and challenges of extra-thick coal seam mining,it deeply explored the selection of reasonable coal pillar width and surrounding rock control strategies to improve mine production efficiency and safety.It also analyzed the characteristics,mining methods,and technical status of extra-thick coal seams,comprehensively analyzed the relationship between coal pillar width and surrounding rock control,providing effective guidance for related fields.
