根据深部软岩巷道大变形、大地压、难支护的特点 ,提出了锚索关键部位二次支护技术 ;并借助数值模拟手段 ,研究了锚索支护调动深部围岩强度的机理。通过在南屯煤矿实际工程中的应用 ,证明了该项技术实用性强 ,可靠性高。 According to the characteristics of large deformation, earth pressure and difficult support in the deep soft roadway, the secondary support technology of the key part of the anchor cable is proposed. With the help of numerical simulation, the mechanism of the surrounding rock strength by the anchor cable support is studied. Through the application in the practical engineering of Nantun Coal Mine, the technology is proved to be practical and reliable.
