To alleviate the boundary effect and to meet the backfill requirements, the waste rock was broken into pieces with dimensions of less than 50 mm, and a standard sifter was used to separate the waste rock into five groups according to particle size: 0–10, 10–20, 20–31.5, 31.5–40 and 40–50 mm. The weight of each sample was 9 kg.According to incomplete statistics, at present, the accumulated amount of waste rock in China exceeds 6 × 10 9 t and more than 1600 waste rock dumps are formed, occupying an area of 1.5 × 10 4 ha. Moreover, about 3 × 10 8 to 6 × 10 8 t of waste rock is discharged annually (Fan et al. 2014 ; Zhang et al. 2009 ).Recycling of crushed waste rock as backfilling material in
