Abstract:To ensure the safe and reliable long-distance reverse slope transportation in the D mining area of the Jinchanghe polymetallic mine, the rheological parameters of filling slurry under different concentrations and cement-sand ratio were tested through the expansion test and rheological test. Based on the pipeline resistance analysis of theoretical formula and numerical simulation, the pipeline transportation resistance and the outlet pressure of filling industrial pump were calculated, and then the reasonable filling process parameters in the D mining area were determined. According to the engineering conditions of filling pipe network in the D mining area, a suitable filling pipeline transportation scheme was formulated to realize the safe and efficient pump filling of paste slurry.
