摘要
单元式充填支护系统采用条带开采的减沉理念,使用新型充填液压支架,仅需将高水充填材料注入采空区条带范围内,待充填材料凝固后即可控制顶板及上覆岩层活动。实践证明,上述方法采煤效率高,充填成本低,能够有效控制地表变形。
Adopting reducing subsidence concept,cell stowing support system applied new-style stowing powered support to transporting high-water stowing material to strip-mining gob.When the stowing material consolidated,movement of roof and overlying strata was controlled.Practice proved that this method could effectively control surface deformation with high efficiency and low stowing cost.
