摘要
为了解决软硬岩层叠合顶板离层破坏、稳定性差的问题,分析了其特有特点,并根据数学公式设计了合理的巷道,明确了锚杆锚索的参数及其布置方式,并在实际工程中有效控制了顶板离层,确保巷道围岩处于稳定支护状态,以期为类似工程顺利进行提供有利依据。
In order to solve the problems of soft and hard rock laminated roof separation failure and poor stability,this paper analyzed its unique characteristics,designed reasonable roadways according to the mathematical formula,defined the parameters and layout modes of bolts and anchor cables,effectively controled the roof separation in the actual project,and ensured that the roadway surrounding rock was in a stable support state,which provides a favorable basis for similar projects.
