软岩巷道变形支护研究与实践

摘要

本文通过对黄陵二号煤矿井下巷道变形数据的实测，对破碎软岩巷道的变形规律及破坏特点进行了研究，得出了其变形规律，并对围岩的变形原因进行了探讨，得出了一些规律，基于巷道的破坏机理分析，给出了破碎软岩巷道支护的原则。研究结果对破碎软煤巷支护实践有一定的指导意义。%According to measured data of the deformation of the mine roadway in huangling no.2 coal mine, Research has been conducted on deformation law of soft rock roadways and damage characteristics, the deformation law was concluded, investigated the reason of the deformation of surrounding rock and some rules are drawn,Base on the analysis on the failure mechanism of the mine roadway , the support principles in mine fractured soft rocks was given. The study results have a certainguidance meaning to the practices of the support projects in mine fractured soft rocks.
