Comprehensive Evaluation Method

For the accuracy of the inrush risk assessment of the problem, put forward in the mine inrush risk assessment using the entropy weight fuzzy comprehensive evaluation method to determine the index weight, through the membership function in fuzzy comprehensive evaluation to quantify the qualitative description of these factors, evaluated the henan jiaozuo mine inrush risk. The results show that the mine water inrush risk grade is "great", the actual mine water inrush accidents have occurred, prediction results conform to the actual situation, and safety evaluation value based on the principle of maximum membership degree is more than analytic hierarchy - fuzzy comprehensive evaluation to get , 0.0696. Thus, the method in the mine inrush prediction can objectively and accurately reflect the actual situation of mine inrush.

Water Environmental Quality

There are lots of methods of evaluating the environmental quality of groundwater. Based on a comprehensive analysis of those common methods, this paper puts forward a method named fuzzy comprehensive evaluation method on water environmental quality based on entropy weight with consideration of toxicology of evaluation factors. Developed from the entropy-based fuzzy comprehensive evaluation method, this method takes into account the influences caused by the toxicology weight and over standard weight of evaluation factors on the calculation of entropy weight. Through some water samples, the evaluation result of this method is more reasonable, objective and comprehensive than the one which is concluded from the entropy-based fuzzy comprehensive evaluation method.
