摘　　要：张集矿第二副井马头门属于深井大断面硐室,针对工程所处地质情况和现有的技术手段,提出采用锚注网喷联合支护方式进行支护,联合一次锚网喷支护以及二次双层钢筋混凝土支护,施工完成后,对其进行了为期60 d的围岩收敛测量。结果表明,与单一的支护方式相比,锚注网喷联合支护效果良好,能够有效控制围岩变形,经济合理,技术可行。The ingate of the second auxiliary shaft of Zhangji mine belongs to deep well large sectionchamber. Aiming at the geological situation of the project and the existing technical means, it isproposed that using of anchor injection mesh and spraying support and combined with a bolt and cablesupport and secondary double reinforced concrete support.After the completion of the construction, themeasurement of the surrounding rock is carried out for 60 days.The results show that the combinedsupport with anchor injection mesh and spraying has good effect, which can effectively control thedeformation of surrounding rock, economically reasonable and technically feasible.
