 To analyze the impact of exhaust emissions from mine hydraulic support transporters on the roadway environment. In this paper, the dispersion distribution of diesel exhaust pollutant during the functioning of a hydraulic support transporters were all-round simulated by Dynamic Mesh of Computational Fluid Dynamics. More specifically, the dispersion and distribution of the main exhaust pollutants CO, HC, and NOx emitted by vehicles under the influence of the roadway wind flow were simulated with computational fluid dynamics (CFD) and the dispersion of exhaust pollutants from hydraulic support transporters during multiple driving phases in an alleyway (from hauling in material, unloading at idle speed, to driving off with no load) was predicted. The simulation results show that the exhaust pollutants emitted during the movement of hydraulic support transporters can pollute the roadway environment and negatively affect gas monitoring devices in the roadway. Therefore, coal mining enterprises should optimize the ventilation design scheme to improve the roadway environment: they should increase the ventilation volume to dilute the emitted pollutants; in addition, the locations of underground gas monitoring devices should be adjusted to avoid interference from exhaust pollutants emitted by vehicles. This paper provides a theoretical basis for the preliminary investigation of the dispersion and transportation characteristics of exhaust pollutants emitted by vehicles in roadways, the research in this paper is of guiding significance to reduce the inhalation of the diesel exhaust pollutants of the miners and reduce the probability of suffering from occupational diseases.
