摘要
针对邢东矿-980 m外水仓由于埋深大,地压显现明显,巷道变形量大的特点,使用钢管混凝土支架进行二次支护,并联合锚喷及后期浅层注浆构建巷道围岩承压环,有效地控制了围岩的变形,保证了巷道长期稳定,为深井巷道支护形式的选择提供了参考。
Based on Xingdong Mine-980 m water sump with large buried depth, obvious ground pressure appearance, large deformation of roadway features, concrete filled steel tube support with secondary support, combined with anchor bolt spray and Late shallow grouting construction of roadway surrounding rock pressure ring, which effectively controled the deformation of surrounding rock, ensured the long-term stability of roadway, provided reference for the choice of deep shaft roadway supporting.
