摘要
根据矿井地质条件,盘道煤业选择了装配隔离墙沿空留巷方案,在实践中采取了加强支护与卸压支护相结合的综合支护方式,较好地控制了顶板变形,研制加工了机械砌块搬运机械设施,提高了施工效率。本项工程为沿空留巷工程的推广应用提供了宝贵的经验。
Based on the mine geological conditions,Pandao Coal Industry Company chooses assembly wall along the empty goaf, and in practice, adopts the comprehensive supporting method, which well controlled roof deformation, developed the mechanical block handling machinery facilities, improving the construction efficiency. This project provides valuable experience for the popularization and application of roadway engineering.
