The invention discloses an old shaft guniting supporting method, and relates to the technical field of mine shaft supporting. The construction method comprises the following steps: mounting a main well mouth guniting machine and a chute; welding a protective barrier at the top of a main/auxiliary cage of a main well and erecting a protective shed; mounting a seamless steel pipe in a main well shaft; connecting a guniting pipeline; by means of the construction mode, the problems that the mine shaft is old and difficult to support can be solved, the guniting supporting work efficiency and the supporting strength can be improved by erecting the protective railings and the protective sheds and re-planning the positions of the pipelines, production can be normally organized after guniting of each shift of the mine shaft, and the influence on normal production is reduced.
本发明公开了一种老旧井筒喷浆支护方法,涉及矿山井筒支护技术领域,施工方法包括以下步骤:主井井口喷浆机及溜槽安装、主井主/副罐笼顶部焊接防护栏杆及搭设防护棚、主井井筒内安装无缝钢管、连接喷浆管路、冲洗井壁、对喷浆机进行供料、进行喷浆作业、收尾作业;该施工方式可解决矿井筒老旧、支护困难的问题,通过架设防护栏杆及防护棚、重新规划管路位置,可提高喷浆支护工作的效率与支护强度,且每班井筒喷浆之后可正常组织生产,减少对正常生产的影响。
