Abstract Cemented paste backfill (CPB) is a sustainable mining technology that is widely used in mines and helps to improve
the mine environment. To investigate the relationship between aggregate grading and different affecting factors and
the uniaxial compressive strength (UCS) of the cemented paste backfill (CPB), Talbol gradation theory and neural
networks is used to evaluate aggregate gradation to determine the optimum aggregate ratio. The mixed aggregate ratio
with the least amount of cement (waste stone content river sand content = 7:3) is obtained by using Talbol grading
theory and pile compactness function and combined with experiments. In addition, the response… More >
