- The dynamic evolution process of the coal gangue particles’ core retention phenomenon in the process of crushing under stress, the evolution law of grading and the corresponding microscopic mechanical characteristics after continuous particle crushing are analyzed. The meso-level which reveals deformation phenomena of granular materials under the action of external loads is highly complex. At the qualitative level, the static compaction process of coal gangue samples can be roughly divided into three stages: initial compaction stage, compaction and crushing stage, and crushing (compaction) stage. It is proved that the interaction of lateral confined unidirectional compression of granular materials is mainly compression.
