摘要
结合凤凰山矿1204工作面动压复用巷道围岩应力分布特性,有针对性地制定了注浆补强方案,通过现场两次注浆的前后对比可知,12041巷顶底板和两帮围岩的变化量都在控制指标范围内,实现了矿井的安全回采。
In combination with the stress distribution characteristics of surrounding rock in reused roadway of dynamic pressure in 1204 working face of Fenghuangshan Coal Mine,this paper formulated the targeted grouting reinforcement scheme.It can be seen from the comparison of the twice grouting on the site that the variation of the roof,floor and surrounding rock of 12041 roadway rock is within the control index,which realized the safe recovery of the mine.
