摘要
针对新阳煤矿新一采区新102工作面10#～11#煤合并层地质及生产条件,该工作面巷道需要在煤柱中掘进,巷道两边为采空区,需要选择合理的支护方式,为了充分发挥锚杆支护的作用,提高巷道掘进施工质量及施工速度,在不改变掘进方法、不增添新设备、不增加施工人员的前提下,通过分析围岩强度、围岩结构、地应力及锚固性能测试,提出了合理的锚杆支护方式,并在施工的应用中取得了显著的效果。
According to the new coal mine a new area in 102 working face of coal new 10~ ~ 11~ merged layer geological and production conditions, the working face roadway in coal pillar of roadway driving,on both sides for the mined-out area, needs to choose the reasonable support way, in order to give full play the role of bolt support in roadway construction, improve the quality and construction speed, without changing the driving method, do not add new equipment, does not increase the construction personnel under the premise, through the analysis of the strength of surrounding rock, rock structure, stress and anchoring performance test, the author puts forward reasonable bolting patterns, and in the construction of the application to obtain remarkable result.
