Abstract:
According to multi-index and complexity of coal mine water hazard influence factors, water disaster safety evaluation index system was established with hierarchical structure, using analytical hierarchy process (AHP) and fuzzy analytic hierarchy process (FAHP) to combine and weight for evaluation indexes, then AHP weight and FAHP weight were linearly combined and done with compromise method, subjective evaluation and objective reflection for the index important degree were fully reflected. Fuzzy comprehensive evaluation model based on compromise weight was established combining with fuzzy comprehensive evaluation (FCE), coal mine water disaster danger data were dug out deeply with evaluation results. According to these, we propose some suggestions on prevention and control water disasters. Application results show that: the evaluation model can quantitatively reflect potential risks of coal mine water disaster in coal mine production system.
