Risk assessment of gushing water in coal mine based on F-ANP model

This study proposes a risk assessment model of gushing water in coal mine based on fuzzy network analysis (F-ANP), and constructs a scientific and comprehensive risk evaluation index system of gushing water in coal mine.The network layer of the system includes four first-level indexes: human, machine, environment and management, including 16 second-level indexes such as surface water and ground water.The fuzzy weighting matrix is established based on the method of fuzzy network analysis, and the weight vector is obtained by calculating the matrix.The risk level of gushing water is judged according to the principle of maximum membership degree finally.The evaluation model is applied to the risk assessment of gushing water in Nanshan Coal Mine, and the evaluation result is a relatively safe level, which accords with the engineering practice.The comparison between the case analysis and the evaluation results shows that the fuzzy network analysis method can better consider the fuzziness and uncertainty of the index in the risk evaluation of gushing water, and the evaluation accuracy is higher and more scientific.
