Floor failure mechanism and aquifuge-grouting reinforcement under narrow strip mining above a confined Ordovician limestone aquifer: a case study of the Weibei Mining Area, China

Abstract Taking a coal mine in the Weibei Mining Area of Shaanxi Province as the engineering background, and focusing on the floor water inrush problem encountered in the mining of narrow strip working faces above the Ordovician limestone confined aquifer, this study effectively overcomes the limita...
