基于矿井开采规模较大、结构较复杂的巷道交岔点,在断层影响范围内施工发生较高冒顶的情况,将几种常见的巷道整修支护方式组合在一起,利用不同支护材料具有的特性,分层次施工,形成复合型的支护结构,确保整修后的巷道长期稳定.“,”Based on the mine roadway in the large scale exploitation and complicated structure of bifurcation points, higher roof caving in fault influence within the scope of construction, several common renovation ways of roadway bolting were combined together, according to different feature of supporting material, the hierarchical construction was made to form a composite support structure, which ensured the long-term stability of roadway after renovation.
