青东矿东翼集中轨道下山综掘施工过程中过遇水膨胀泥岩,同时巷道施工过程中受8煤底板砂岩裂隙水、钻孔水影响,给施工和支护带来了困难。本文详细阐述了东翼集中轨道下山在施工上和支护上采取的有效举措,实现了安全高效生产,同时为今后类似条件下的施工提供了宝贵的经验。
During the construction process of centralized orbit downhill excavation of the east wing of Qingdong Mine, water swelling mudstone has been encountered. At the same time, due to the influence of fissure water and borehole water of sandstone in 8 coal floor during roadway construction, difficulties are brought to the construction and support. This paper elaborates on the effective measures taken in the construction and support of the centralized orbital movement of the east wing in order to realize safe and efficient production and provides valuable experience for the construction under similar conditions in the future.
