分析了松散含水层下巷道围岩变形特征,结果表明不稳定煤巷围岩的变形主要是顶底板的变形,由此提出了控制该类巷道围岩变形的技术措施:高性能锚杆支护技术、预应力锚索强化技术和围岩加固技术。该研究成果在现场得到了广泛的应用,正逐步推广应用到整个矿区。
The deformation characteristics of the surrounding rock of the roadway under the loose aquifer are analyzed. The results show that the deformation of the surrounding rock of the unstable coal roadway is mainly the deformation of the roof and floor, and the technical measures to control the deformation of the surrounding rock of this kind of roadway are put forward: high performance bolt support Technology, prestressed anchor reinforcement technology and reinforcement of surrounding rock. The research results in the field has been widely used, is gradually being applied to the entire mining area.
