| 摘 要： | 对淮南朱集矿轨道巷进行两帮收敛、拱顶沉降、底臌和锚索拉力的现场监测，基于监测结果，阐明轨道巷在相邻的胶带巷和回风巷扰动影响下围岩变形和锚索拉力的变化趋势。监测结果表明：轨道巷围岩受到了回风巷和胶带巷的扰动；变形经历较长时间后达到稳定，且底臌值大于两帮收敛和拱顶沉降；胶带巷和回风巷对轨道巷的扰动影响程度和巷道群的空间布置相关，在巷道间距大于5倍硐径情况下扰动仍然存在，而且扰动影响不是突变性的，具有时空效应。

| Abstract: | The on-site monitoring of horizontal convergence,crown settlement,floor heave and anchor cables tensile force was carried out in railway laneway during the construction of roadway group.According to monitoring results,the variation trend of surrounding rock deformation and tension of anchor cables was clarified.Conclusions are presented as follows:surrounding rock mass of railway laneway is disturbed by excavation of neighboring roadways;surrounding rock achieves a steady state after a long term,and floor h... |
