摘要
以深井受2次回采动压影响14103辅运巷为研究背景,通过围岩地质力学测试及2次工作面回采动压影响下煤柱内部应力观测,得出巷道受上区段工作面采后及本工作面超前采动应力影响较大;留设55m煤柱,并采取适当支护方式,可有效控制巷道围岩变形,保证矿井安全生产。
the deep influenced by the two mining dynamic pressure 14103 auxiliary transport lane as the research background, through the surrounding rock geological mechanics test and two mining face under the influence of dynamic pressure pillar inner stress observation, draw on the section of roadway face after mining and the working face advancing mining influence on dynamic stress; The 55 m coal pillar is set up,and appropriate support mode is adopted to effectively control the deformation of roadway surrounding rock and ensure the safe production of mine.
