Abstract: Mine dust threatens body health of the miners seriously, which serves direct influence of pneumoconiosis occupational disease. For realizing moisture-controlled dust removing goal and revealing the moving and deposition law of the dust at the tunnelling face in coal mine, a corrosion-resistant and moisture-controlled dust removal experiment platform was developed to provide platform support for teaching research and engineering practice of mine dust removal, which was composed of roadway shelter, dust raising, ventilation, dust removing and data monitoring sub-systems. The experimental platform used corrosion-resistant metal materials and surface spraying materials to achieve the purpose of anti-corrosion in the high humidity environment of the mine, and adopted foam dust removal to achieve the effect of moisture control in the tunneling face. The dust expansion characteristics around the comprehensive roadheader was studied by the platform, whose moving speed rose first and decreased subsequently under the influence of the ventilation system. An experiment was designed to investigate the effects of four factors on dust removal efficiency, including dust concentration, dust pressure, nozzle pressure and dust particle size. The variation curve of dust concentration in fully mechanized tunneling face was divided into two stages: dust stage and dust removal stage. In the dust removal stage, the rate of dust reduction increased with the increase of dust collector concentration, the decrease of dust pressure, and the increase of dust particles. When the nozzle pressure was 0.5 MPa, the foam spray diffusion angle and specific surface area were the largest, the penetration ability was the strongest, and the dust removal effect was the best. The experimental platform is capable to present dust generation, moving and reduction characteristics in fully mechanized tunneling face for the teaching research and mining technical personnel and provide moisture-controlled dust removing method reference for coal mine.
