The crushed‐stone which is been broken into -10mm from waste rock and with continuous gradation has been used as backfill aggregate in Xinglong Mine of Xingfa Chemical Group .And the pumping concrete backfill process has been selected in this mine .After carrying out the slurry mobility tests and ratio tests ,the concentration of the slurry has been chose as 82% and the aggregate‐to‐cement ratio has been chose as 4 .And these parameters can meet the requirements of pumped transmission and stoping strength .
