Abstract
Coal floor water bursting has been one of important problem in coal mine safety production.Therefore,choosing reasonable and accurate evaluation method to evaluate coal floor risk has great significance to guide the safe production of coal mine.The method of grey correlation analysis takes data sequence as the research object.And the first is to get the correlation coefficient of each scheme and the ideal scheme composed of the best indicators,then to get relational degree again by the correlation coefficient.In this paper,the method of grey relational degree analysis is applied to water bursting hazard evaluation and establishes grey correlation matrix between the evaluation unit and the reference sequence.Which improves the calculation method of Deng grey relational degree by introducing the weight and ensures the final comprehensive evaluation results more accurate.关键词
