Study and Prevention on the Diffusion Rule of Dust Pollution in the Coal Mine Whole-Rock Fully Mechanized Workface

The mathematical model of solving two-phase flow of gas and dust particles was built by established the k-ε-Θ-kp equation. Moreover, by using FLUENT software, the diffusion rule of dust pollution in the whole-rock fully mechanized workface was researched with different air-draft amount. The result showed that when the air-draft amount increased from 320m3/min to 600m3/min, de-dust ability of extraction fan drum is gathering strength, pervasion intensity of producing dust is continuously decreased in tunneling place. The simulation results of each measuring point are basically consistent with the field measurement results.
