摘要
针对深埋煤层坚硬顶板回采巷道围岩应力较高,顶板来压强烈等特点,以龙顶山矿9011工作面运输顺槽实际地质条件为背景,利用理论分析的方法,对巷道锚杆支护参数进行分析研究,确定巷道合理支护方案,并通过现场实测检验支护效果,为类似条件下回采巷道支护设计提供参考。
Aiming at the impact of dynamic pressure and high ground stress in deep mine with hard roof,the strong mine pressure behavior,take Longdingshan coal mine 9011 working face actual geological conditions as background,by using the method of theoretical analysis,to research and analyze roadway bolt support parameters,determine the reasonable support scheme of roadway,and through the field measurement inspection supporting effect,provide a reference for similar conditions of extraction roadway support design.
