The Application of Unascertained Measure Model to Synthetic Evaluation for Underground Fire Risk of Bofang Coal Mine

Based on the unascertained theory, the paper elaborated exhaustively the modeling process of the unascertained measure model. Combined with the unascertained measure model, the safety factors affecting underground fire are analyzed and evaluated. According to the reality of Bofang coal seam 3, we can collect the measured data, determine the fire risk evaluation index, calculate for example by using the unascertained measure model, and evaluate the underground fire risk level of Bofang coal mine. The result is found to be in accordance with the reality, after it is verified.The method is designed to enhance the effectiveness of synthetic evaluation for underground fire risk , as provided the proper safety measures basis for the departments concerned.
