In this study, the acoustic emission evolution and stress drop processes of brittle coal specimens under quasi-static compression were investigated by experiments and numerical simulations, to reveal the pattern of mesoscopic crack evolution and its

The effect of intermediate stress (in situ tunnel axial) on a strainburst is studied with a three-dimensional (3D) bonded block distinct element method (DEM). A series of simulations of strainbursts under true triaxial in situ stress conditions (i.e.

Abstract Strainbursts induced by cyclic disturbance with low frequency (termed as cyclic‐induced strainbursts) are major dynamic disasters during deep excavation and mining. There is currently no quantitative criterion available for the prediction

Abstract The design of dam bodies for underground reservoirs must account for how water affects shear failure and the evolution of fractures in coal pillars. In this work, we detect acoustic emissions in raw coal samples with different water content

Mineral consumption is increasing rapidly as more consumers enter the market for minerals and as the global standard of living increases. As a result, underground mining continues to progress to deeper levels in order to tackle the mineral supply cri
