The paper uses the theory of fuzzy comprehensive evaluation to solve the problem about the safetyAbstract: In gas prediction and prevention , it is important for the Mine-managers to know coal-seam gaspressure.assessment of water inrush from roof and floor of coal seam, and studies its feasibility. The paper introducesAbstract: In gas prediction and prevention , it is important for the Mine-managers to know coal-seam gaspressure.how to establish the evaluation model of water inrush from coal floor, and focuses on using the analyticAbstract: In gas prediction and prevention , it is important for the Mine-managers to know coal-seam gaspressure.hierarchy process to determine the weight of different valuation factors. Finally, the evaluation results weAbstract: In gas prediction and prevention , it is important for the Mine-managers to know coal-seam gaspressure.obtained can provide a reference and basis for developing preventive measures of water inrush from roof andAbstract: In gas prediction and prevention , it is important for the Mine-managers to know coal-seam gaspressure.floor of coal seam.
