Popis:	Coal dust explosion is a major accident affecting the safety of coal mine production. In order to control coal dust explosion, using inert dust to suppress explosion is one of the effective methods. Taking the gas-fat coal as the research object and CaCO3, NaCl, and NH4H2PO4 as the inert dust, the suppression effect of inert dust on gas-fat coal dust explosion pressure and flame is studied. It is found that when the gas-fat coal dust particle size is 48~58 ?m, both the maximum pressure and the farthest distance of flame reach the maximum value. Among the three inert dusts, NH4H2PO4 has the best suppression effect, followed by NaCl, and CaCO3 has the worst suppression effect on explosion. The smaller the particle size of
