联合支护技术在深部软岩巷道中的应用
Application of combined support technology in soft rock laneways
摘要
Abstract
Large deformation phenomena are induced by the high in-situ stresses for the red shale laneways in the phosphorite mine of Guizhou Kailin group, such as rock fracturing, rock expansion and squeezing deforma-tions. To avoid the failure of the laneway and multi-repairs, a combined rock support technology is proposed based on mechanical characteristics of the red shale and modern support theory. It is included that combining the long cable, shot-crete, rock-bolt and steel meshes. The results show that the proposed rock support method can significantly improve the support strength and stiffness by engineering practical comparison, which has reference value to the development and application of deep soft rock supporting technology.关键词
