Ground control systems for deep underground mining: Advancing safety and resource recovery in high-stress mining environments

This paper addresses the growing challenges of ground control in deep underground mining environments in the United States, where increasing depths introduce significant safety and operational concerns, including squeezing ground conditions, time-dependent deformation, and seismic activity. We examine the evolution of ground support technologies, focusing on energy-absorbing systems, dynamic surface supports, and innovative materials specifically designed for high-stress conditions. Through analysis of case studies from major U.S. mining operations, we demonstrate the effectiveness of convergence confinement methods and specialized gabion-like systems in enhancing both safety and resource recovery. The integration of artificial intelligence, remote sensing, and IoT-based monitoring systems represents a paradigm shift from reactive to proactive ground management strategies. Our findings indicate that successful ground control requires a multi-faceted approach combining advanced support design, real-time monitoring technologies, and strategic maintenance practices. These advancements significantly contribute to the sustainability and economic viability of deep mining operations, particularly important as the industry increasingly targets critical minerals essential for clean energy transition.
