To address the problems of key layer instability and intense ground pressure during mining under overlying concentrated coal pillars in shallow buried close-distance coal seams, this study takes the 12,101 working face of Halaigou Coal Mine as the research object. By comprehensively adopting methods such as theoretical analysis, similarity simulation experiments, numerical simulation, and field m…

The study aims to scientifically substantiate optimal drilling-and-blasting (D&B) parameters for driving underground mine workings under complex geological and mining conditions at the Akzhal deposit. The work addresses the selection of explosive types and the rational depth, configuration, and design of cut boreholes, together with their blasting pattern (BP), to improve rock-mass stability, ope…

At the bottom of the Resolution Copper mine , the difference between a safe workday and a dangerous one can hinge on water and heat. To keep underground working conditions safe, engineers must anticipate how fast groundwater will flow into the mine and how hot it will become as operations change. But deep underground, those forces are difficult to predict. That’s where a digital twin comes in. Ne…
