Water Abundance Comprehensive Evaluation of Coal Mine Aquifer Based on Projection Pursuit Model

Abstract: After coal mining, mining fissures develop, which may lead to an overlying aquifer and water inrush. Objectively and accurately evaluating and predicting the water abundance of the bottom aquifer of the Cenozoic are of great significance for ensuring safe mining of shallow coal seams and for the protection of water resources. The water richness evaluation index data has characteristics of high dimensionality, nonlinearity, and nonnormal distribution, and therefore, results often cannot objectively and truly re… Show more

“…However, the water yield of aquifers directly affects the occurrence and frequency of water inflow [5]. Moreover, due to the influence of coal seam mining, the water yield of aquifers changes dynamically, and the borehole data are scarce and cannot be characterized globally in space [6]. Therefore, it is of great practical significance to do a good job in predicting roof water yield to reduce water inflow accidents and ensure coal mine safety in production.…”
