Abstract：Based on the features of roof water disasters in Southwest Karst area in China and starting from the features of water source, the mining disturbance, the performance of water-resisting layer and geological structure, analysis and choice were made on the corresponding evaluation indexes. Combined with fuzzy analytic hierarchy process, the weight of the evaluation indexes was determined, and an evaluation index system and evaluation method for roof water disasters in coal mines in southwestern Karst area were discussed. In addition, risk evaluation was made on the roof water disaster in a typical mine according to a specific engineering example, all of these can provide a certain reference for predictive evaluation of roof water disasters in coal mines in the future.
