摘要
充填夯实支架是充填开采中的关键设备。通过在唐山矿的工业性试验表明:物料充填开采液压支架设计合理,充填效果良好,经地面及井下观测数据分析,地表沉陷量达到了预期效果。
Filling reinforce bracket is filled with the key mining equipment. By industrial test showed that the material Tangshan Mine backfill mining hydraulic support rational design, filling good effect by surface and underground observation data analysis, surface subsidence amount to achieve the desired effect.
