摘要
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 indutrial trials, strasta behavior of mine in deep workings repaired is measured by using field measure technique. Measure results indicate that deformation rules in deep workings repaied are diffetent from others. There are increasing period and stabilizing period in deep working repaired.
