At the microscale, the presence of pores, grain boundaries, and pre-existing fractures can lead to high stress concentrations under increasing load. At the macroscale, foliation or bedding planes are characterized...

... Abstract Stress concentration and rockburst risk in coal mine are associated with the occurrence of competent strata in overburdened coal seams. Benches of sandstone and conglomerate are difficult unbreakable and a high level of elastic energy is stored there. It can be released as a rockburst...
