| 摘 要： | 根据“巷道围岩松动圈支护理论”，以南屯矿３上 煤层综放工作面全煤平巷围岩条件为基础，对不同动压系数、侧压系数、锚杆支护参数条件下，锚杆支护巷道围岩应力分布、围岩变形及巷道破坏规律进行了模拟试验．试验证实，矩形煤巷顶板中存在一个卸压区，巷道两帮和角部区域围岩破坏严重，是支护的重点部位．锚网支护能有效控制采动压力影响下全煤巷道围岩的稳定性．试验得到的结论对于综放全煤巷道锚网支护设计和应用具有指导意义． |

| Abstract: | On the basis of the roadway support theory of broken rock zone and the geological column of coal seam 3 1 in Nantun Coal Mine, the stress and deformation patterns as well as the typical failure characteristics of surrounding rock are studied under different pressure levels and different bolting mesh support parameters. It is proved that there is a low stress area in rectangular roadway roof. Surrounding rock in two sides and corner areas are severely broken under high pressure produced by mining activity. So, these areas are the major supporting zones.Bolting mesh support is effective to keep surrounding rock of full coal mining roadway in good conditions.Conclusions resulted from the test are helpful for further application of bolting support in coal roadways. |
