Abstract:According to the principle of the“spherical shell destabilization”theory , the expansion energy of initial relased gas and the thickness of soft coal are defined as the test indexes to predict the dynamic phenomena when coal is uncovered in a cross-cut . A lot of test data corresponding to various dynamic phenomena are determined in 46 experiments of outburst simulation . Handled these data with Bayes ultigroup progressively discriminatory analysis method , established criterion function for three dynamic force phenomena during coal uncovering in a cross-cut , and its repeatable accuracy is up to 100 %.
