The paper presents an experimental investigation on the pressure field of dust clouds explosion in free air.The parameters of blast field based on the multinary solid dust ignition explosive are measured by the technology of pressure sensors and high-speed photo. The over-pressure curves, and high-speed photos of dust explosive test and liquid-PO test are presented. The experimental results show that the over-pressure peak of dust clouds explosion is great. In the dust clouds there is a section where the pressure is lower than the pressure at the central and verge of dust clouds. The effectible time of the dust clouds explosion is much larger than that of the liquid PO clouds.
