在通风系统改造中,需要扩大回风竖井的断面,其中一段采用锚杆喷射混凝土支护获得成功,可供地方煤矿或各类煤矿资源整合期间新增井筒的同类型工程借鉴。阐述了工程的可行性和施工工艺,介绍了工程质量控制等方面的施工经验。
In the ventilation system transformation, needs to expand retum air shaft of the cross - section, one of them is successful for using bolt shotcrete support, which could provide a reference for the same type of project of various local coal or coal resources during the integration of the new shaft. Described the feasibility and construction process of the project and construction experience of engineering quality control.
