| Abstract: | Based on the uncertainty measurement theory, a risk prediction method of coal seams outburst was established. An unascertained measure model was constructed and the unascertained measure values of all evaluation indexes were calculated. The weights for indexes were calculated by entropy weight theory, and the result of coal seams outburst risk prediction can be obtained according to credible degree criteria. This method can solve a lot of unascertained problems in risk prediction method of coal seams outburst, and also can analyze the unascertained problem quantitatively. Exemplification indicates that the evaluation result is consistent better with actual instance if the method of the uncertainty measurement theory is applied in the risk prediction method of coal seams outburst. |
| Keywords: | uncertainty measurement theory credible degree coal seams outburst risk prediction |
