大跨度、大断面巷道锚杆锚索联合支护机理研究

Span,Bolt and Cable Tunnel Large Section of Support Mechanism

随着综采工作面设备的大型化,开采强度与产量的大幅度提高,要求的巷道断面也越来越大,大大增加了支护难度,单锚杆支护已很难满足支护要求,文章就锚杆-锚索联合支护的作用机理和在切眼支护设计中的实际应用,以及支护效果进行了研究。

Mechanized mining face with large-scale equipment,mining intensity and yield a substantial increase,the required roadway section is also growing,has greatly increased the difficulty of supporting a single bolt support has been difficult to meet support requirements,article on the bolt-the role of anchor combined support mechanism and cut support in the practical application of the design,as well as supporting effect was studied.
