Abstract

The high cemented gangue backfill (HCGB) is prepared from coal gangue, fly ash, cement and water. The effects of curing period, slurry concentration, fly ash content and cement content on the uniaxial compressive strength (UCS) of HCGB were studied by single factor and multi-level test method. The results show that: the UCS of the HCGB follows an exponential function with slurry concentration, an exponential function with curing period also, but a power function with cement content, and decreases after increasing with increasing of fly ash content.
