Common Discrimination Method and Evaluation of Water Inrush Source in Mine

摘要

Discrimination of mine water inrush source has always been the focus of academic circles. In order to do a good job in mine water inrush prevention and control, it is necessary to find out the source of mine water inrush. Combining with the relevant research results in recent years, this paper focuses on discussing several commonly used methods for identifying mine water inrush sources, such as conventional hydrochemical characteristics discriminant method, isotope analysis method, distance discriminant analysis method, BP neural network method, etc, pointing out their respective advantages and disadvantages. It is concluded that each method has its limitations, selection and determination methods should be based on the actual situation of hydrogeology and comprehensive utilization of various methods, which can greatly improve the accuracy of water inrush source identification and overcome the shortcomings of single method. It can provide some reference and guidance for related research work.
