深埋煤矿巷道锚杆支护设计探讨

Discussion on Tunnel Bolting Design for Deep Coal Mine

合理有效的锚杆支护理论是巷道支护设计的关键。以岩石具有自稳能力为前提,对巷道开挖后岩体不稳定区域进行了划分,以此作为锚杆支护设计的参照标准。以白羊岭煤矿东翼回风大巷为例,进行了相关锚杆支护设计。数据监测表明,该支护设计方法合理可行,具有推广价值。

The reascnable and effective bolting theory is the key of roadway design. Taking one coal tunnel as the example, this paper discusses the design of the relative bolting support. The clam detecting shows that this support design is reasonable and feasible and should be popularized.
