| 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. |
