Research Status and Development Trends of Mine Floor Water Inrush Grade Prediction

Abstract

According to the characteristics of mine floor water inrush, its influence factors can be summarized as the geological structure and mining pressure, the aquifer water properties, and the water resistance ability of floor strata; the mechanism of each influence factor is described herein. The research history and status of mine floor water inrush are introduced, and the commonly used prediction methods of mine floor water inrush grade are summarized and categorized as empirical formula methods and GIS technology, mathematical analysis methods, nonlinear mathematical analysis methods and simulation experiment methods; a detailed analysis of each method is presented. With the development of big data, cloud computing and nonlinear algorithm research, the existing deficiencies of floor water inrush prediction methods will likely be addressed by the future research and development trends of mine floor water inrush grade prediction.
