A new study combined SEM, XRD and NMR pore characterization with six machine-learning models on 37,227 well-log records, ...
SINGAPORE, May 21 (Reuters) - Thousands of metres below its vast coal basins, China is tapping an unconventional fuel source in a multi-billion-dollar effort to unleash new supplies of natural gas and ...
A new numerical study shows that in-situ stress ratio, bedding dip angle and hydromechanical coupling jointly control ...
Coal-rock composite systems, prevalent in deep mining and underground engineering, exhibit complex interactions between soft coal seams and stiffer rock layers. Their mechanical behaviour under load ...
Researchers develop a gangue–paste backfilling method that reduces simulated roof displacement and limits surface subsidence ...
Rock bursts, commonly associated with coal mining activities, involve the abrupt release of elastic energy from rock masses. Recognized as a major challenge in mining engineering and rock mechanics ...
