The explosion characteristics are shown in Table 1. The ignition energy of the coal powder is 50mJ, so electrostatic and mechanic sparks should be considered as ignition sources. The explosion index K max is less than 10 MPa.m/s, so venting and suppression are effective for the coal powder. Table 1: Explosion characteristics of the coal powder
