A mathematical model of relation between dust explosion rate on a coal face and design parameters of a shearer drum is set up by supposing and simplification in the paper.With a drum shearer made in china as an example,relative curves of drum diameter,number of spiral vane on a drum and duct explosion rate on a coalface are given by means of computer simulation with the mathematical model and effects of each parameter on duct explosion rate are determined by analysis,which provides a theoretic basis for forecasting effects of different structure parameter shearer on duct explosion rate,perfecting a appraising system of shearer working performances,improving the drum design,reducing cutting dust of a shearer,lowering duct explosion rate and increasing safety of coal production.
