Apr 30, 2020 The results show that the particle size and loading rate of coal gangue exert a significant influence on the deformation and energy dissipation of coal gangue. Guo et al. 11 studied the effect of particle composition on the creep of gangue under step loading by creep compaction testing of crushed stone with different particle compositions.

In this research, the particle size distribution and permeability of saturated crushed sandstone under variable axial stresses (0, 2, 4, 8, 12, and 16 MPa) were studied. X-ray Computed Tomography results revealed that particle crushing is likely to occur considerably as the axial stress is approaching 4 MPa, which results in the change of pore structure greatly.

We have used X-ray photoelectron spectroscopy (XPS) to study the variation of surface pyrite density with coal particle size (53 4m - 250 4m). We also detect and monitor pyrite oxidation to sulfate, an important process influencing the surface-dependency of coal-cleansing methods such as flotation. It is very likely that as coal is crushed as part of the processes employed to rid it of ...
