TY - JOUR TI - The influence law of pipe-line transportation flow of multi-source coal-based solid waste filling materials AU - Ge Guang-Heng AU - Gong Peng AU - Ma Zhan-Guo AU - Xu Min JN - Thermal Science PY - 2025 VL - 29 IS - 2 SP - 1539 EP - 1544 PT - Article AB - Aiming at the problem of long-distance transportation of multi-source coal-based solid waste filling materials, combined with the physical characteristics of multi-source coal-based solid waste filling materials, the reliability of the simulation results is verified by comparing the numerical simulation with the measured data of the ring pipe experiment. The straight pipe conveying characteristics of multi-source coal-based solid waste filling slurry were studied by numerical simulation, and the variation law of resistance along the pipe during the flow of slurry in the pipe was obtained.
