摘要: 针对深部高地应力软岩巷道支护技术难题,选取红四煤矿+280m水平西翼轨道石门作为研究对象,开展了巷道围岩地质力学参数测试,对巷道围岩岩性、围岩强度、地应力参数进行测试分析,并基于测试分析结果提出了深部高地应力软岩巷道控制原则,确定了合理支护参数并应用于现场实践。由现场实测可知,该控制技术能够有效控制深部高地应力软岩巷道的围岩变形。

Abstract: To solve the supporting technical problem of soft rock roadway under high geo-stress in deep mine, this paper selects rail cross-cut of +280m level West Wing in a Coal Mine of Jilin Province. And the surrounding rock lithology, surrounding rock strength and in-situ stress parameters are tested and analyzed, based on geological mechanics parameter test of roadway surrounding rock. In view of the test and analysis results, the control principle of deep high ground stress soft rock roadway is put forward. The reasonable supporting parameters are determined and applied to field practice. After applying in field test , the result showed that the support technology can effectively control the surrounding rock deformation of soft rock roadway under high geo-stress in deep mine.
