Abstract:
With increasing mining depths and increasingly complex geological conditions in non-coal mines, ensuring safety during production presents unprecedented challenges. As a pivotal technology for subsurface imaging, geophysical methods have evolved from serving solely as exploration tools to becoming core technologies for safety management throughout the entire mining lifecycle. This paper systematically reviews the current applications of various geophysical technology (including gravity, magnetic, electrical, and seismic techniques) in identifying hidden hazard factors, enabling dynamic monitoring and early warning, and conducting risk assessments in mines. It critically examines the existing fragmentation in the application of these technologies. Furthermore, the paper explores the deep-integration mechanisms of cutting-edge technologies−such as space-air-ground integrated surveys, artificial intelligence (AI) recognition, and big data analytics−with mine safety management practices. A novel integrated “prospection-monitoring-assessment” (PMA) framework for non-coal mine safety is proposed, detailing its theoretical foundation, technical system, and implementation pathways. Finally, addressing current technological bottlenecks and future needs, the paper outlines promising research directions, aiming to provide both a theoretical reference and technical guidance for advancing the modernization of safety governance capabilities in the non-coal mining industry.
