| 摘 要： | 通过对唐山矿区9煤层T2291工作面溜子道实施锚杆支护时,进行全煤巷道的矿压观测,说明了同煤岩层内不同部位处巷道应力的差异和相同巷道应力条件下不同煤岩强度处围岩变形的差异;通过分析,得出9煤层锚杆支护巷道的围岩变形、锚杆受力等情况和矿压显现规律,提出锚杆支护巷道在进行设计及施工方面的指导性意见。

| Abstract: | Bolting on T2 291 working face of NO.9 coal seam in Tangshan mining area,and the observation of the mining pressure of all tunnels show the difference of tunnel stress in different places of the same coal seam and the difference of country rock deformation in the places with different coal rock strength under the same tunnel stress.Through analysis,we get the results of country rock deformation and the anchor bearing pressure of bolting tunnels in NO.9 coal seam and the laws of mining pressure revelation,put forward guiding views in design and construction of bolting tunnels. |
