在工业性试验的基础上,应用现场测试技术对深部返修巷道矿压显现进行了测试。测试结果表明:返修巷道围岩变形规律与新开掘巷道围岩变形规律有明显的不同。返修巷道围岩变形一般存在变形增长期和变形稳定期。在围岩变形增长期中,围岩变形增长幅度小,增长期长。由此可为深部返修巷道支护参数设计和理论研究提供依据。 Based on the industrial test, the field test technique was used to test the underground pressure of deep reworked roadway. The test results show that the deformation law of the surrounding rock of the repaired roadway is obviously different from the deformation law of the surrounding rock of the newly excavated roadway. The deformation of surrounding rock of rehabilitated alley generally has deformation growth period and stable deformation period. In the surrounding rock deformation growth period, the surrounding rock deformation growth rate is small, long growth period. This can provide the basis for the design and theoretical research of deep rehabilitate roadway support parameters.
