摘要
针对新庄煤矿3103工作面顺槽巷道顶底板变形严重影响正常回采的现状,分析了围岩变形机理,应用了二次注浆加固技术。现场试验表明,该技术能够有效控制破碎围岩的整体岩性,提高巷道支护效果,为所在盘区其他工作面的回采提供了数据参考。
Aiming at the present situation that serious roof and floor deformation of roadway along roadway in 3103 working face of Xinzhuang Coal Mine affects normal mining, this paper analyzed the deformation mechanism of surrounding rock and applied secondary grouting reinforcement technology. Field tests showed that the technology could effectively control the whole lithology of broken surrounding rock and improve the supporting effect of roadway, which provides data reference for other working faces in the panel.
