摘要

为解决杨河煤业高应力软岩巷道的支护问题，对深部软沿巷道变形破坏特征及原因进行分析，提出支架-锚杆-围岩卸压耦合支护技术，并结合42轨道下山试验巷道对耦合卸压支护技术参数进行阐述，通过矿压观测结果可知，42轨道下山在采用卸压耦合支护技术后，有效控制了巷道强烈变形。

Abstract：

In order to solve the soft rock roadway support of Yanghe Mine, the roadway failure features and reason were analyzed, the technology of coupled support for the unloading pressure of support - anchor - surrounding rock was put forward, combined with technical parameters of coupling unloading support of No.42 roadway downhill test, mine pressure observation results showed that the roadway deformation got control after the application of unloading pressure coupling support technology.

Key words： soft rock roadway coupling support structural compensation mine pressure observatio
