淮南张集矿区第二副井箕斗装载硐室属于深井大断面硐室,针对工程所处地质情况和基于现有支护技术手段的分析,提出采用锚注网喷联合支护技术对硐室进行支护。支护后的现场监测结果表明:该支护技术能够很好地控制围岩变形,保证了硐室围岩的稳定和矿井的高效生产。
The second auxiliary shaft skip loading cavern in Zhangji mining area of Huainan belongs to the deep section large section chamber. According to the geological conditions of the project and the analysis based on the existing supporting techniques, Support. The monitoring results after the support show that the support technology can well control the deformation of the surrounding rock and ensure the stability of the surrounding rock and the efficient production of the mine.
