Based on the movement characteristics of overlying strata with gangue backfilling, the
compression test of gangue is designed. The deformation characterristics of gangue is …

The behavior of a sand-steel interface can be different than the shearing behavior of a sand.
This study focuses on the effect of shear loading on a sand-to-sand and a sand-steel …

This study probed the compaction-deformation and breakage characteristics of loose broken
coal under stress–temperature coupling loads. The constitutive model of loose broken coal …

Particle geometry is a result of natural processes, such as the genesis of parent rock, particle
transportation and depositional history. For granular materials, the particle morphology has …

Single-grain crushing tests were carried out on limestone with nominal particle sizes of 2.5,
5, and 10 mm to investigate the effect of particle size and acidic erosion on grain strength …

Grain breakage affects a number of geotechnical engineering problems. In this research
study, the breakage of an artificial, porous granular material (light-expanded clay aggregate …

In order to better understand groundwater influx and protection in coal mining extraction
works, an in-house water flow apparatus coupled with an industrial rock testing system …

A series of single-particle crushing tests was carried out to investigate the size effect of
coarse-grained mudstone soil strength with three categories of nominal particle size, 2⊙ 5 …

The coarse-grained soil is prone to particle breakage under external loads and other factors.
A series of single-particle fragmentation tests is conducted for mudstone and sandstone …

Whereas the crushing of solid soil particles has been studied for decades, there is very little
research performed on the micromechanics of hollow particles crushing. In this paper a …
