摘要
通过对施工巷道地质力学评估及围岩类型判别,设计耦合支护参数,在现场观测的基础上,确定巷道支护关键部位,验证支护参数,制定巷道支护及防治底板下滑的措施。
This paper through the construction of geological rock types of mechanical assessment and determine the design parameters ot coupling support, on the basis of observations at the scene to determine the roadway key component, validation support parameters, to develop roadway and prevention floor down measures.
