【摘要】 在对粉煤灰物理力学性质和化学成分测定分析的基础上，依不同粉煤灰添加量进行了粉煤灰全尾砂胶结充填强度试验，结果表明水泥:粉煤灰：尾砂为１：２：６的充填体可满足人工矿柱构筑要求，且成本比不加粉煤灰试块降低２６．４％．更多还原

【Abstract】 According to the physical, mechanical and chemical properties of flyash, cemented crude tailings fill experi- ment was carried out with different amount of flyash. The results indicated that fill strenghth with 1:2:6 ra-tio of cement, flyash and crude tailings could meet the requirement of artificial pillar, and its filling cost was 26.4%lower than that of fill without flight.更多还原
