通过采用锚梁网索支护技术,有效地控制了复合顶板软岩的离层和巷道的变形,提高了工程质量和单进,减少了事故的发生,取得了较好的支护效果和经济效益。
2.
The experimental condition of the roof bolting with bar and wire mesh in the gob-side entry in 1222(3) Zhangji coal mine is introduced.
介绍了张集矿1222(3)沿空巷道锚梁网索支护的试验情况,通过对沿空巷道锚梁网索支护段和29U型钢架棚支护段巷道围岩变形观测,证明在复合顶板条件下,沿空巷道采用锚梁网索支护明显优于采用29U型钢架棚支护。
2) support with anchor cable network
锚网梁索支护
1.
The support with anchor cable network is applied when No.
介绍了祁东煤矿7115风巷过落差3 m的正断层,在高地应力、大断面的条件下,使用锚网梁索支护技术的成功经验,为该矿煤巷过断层施工提供了新的支护方法,为类似条件下掘进巷道提供了很好的依据和借鉴。
4) bolt(cable)beam net timbering
锚杆(索)梁网联合支护
5) CSBBWC
锚梁网索联合支护
1.
Three steps should be taken:Firstly, the former entry should be reinforced by combined support of bolt, bar, wire mesh and cable (CSBBWC), and the primary ladder-shaped steel support should be removed; Secondly, in the reinforced entry, the coal wall of the next coalface should also be en.
试验分三步进行:第一步,对原巷采用锚梁网索联合支护实施加固,撤掉梯形架棚;第二步,在已加固巷道下一工作面侧煤壁,实施扩帮锚网支护;第三步,在原巷位置实施巷内充填,并加固充填体。
6) bolting with wire mesh and beam
锚网(索)组合梁支护
补充资料:喷锚支护
喷锚支护 combination of anchorage and shotcrete support 把锚固和喷混凝土结合起来,用以加固地下洞室围岩的措施。喷混凝土是利用喷浆设备向地下洞室开挖面喷一定厚度的混凝土层,借以支护围岩。由于混凝土喷层密贴围岩,并具柔软性等特点,所以能承受较大荷载,并能控制围岩变形,充填胶结岩体表层裂隙,保护和发挥岩体的潜力。喷混凝土可以作为洞室围岩的初期支护,也可以作为永久性支护。喷锚支护是使锚杆、混凝土喷层和围岩形成共同作用的体系,防止岩体松动、分离。把一定厚度的围岩转变成自承拱,有效地稳定围岩。当岩体比较破碎时,还可以利用丝网拉挡锚杆之间的小岩块,增强混凝土喷层,辅助喷锚支护。 |
