Experimental Study on Nonuniform Compaction and Re

The crushed coal gangue particles are widely used in solid backfilling. However, the nonuniform compaction and internal recrushing behavior of crushed coal gangue under bearing stress have not yet been revealed in current research. But this is Standard Test Method for Bulk Density of Crushed ,Significance and Use 3.1 This test method concerns the compaction of crushed coal to determine either its compacted or uncompacted bulk density, for Seepage properties of crushed coal particles ScienceDirect,A self–made gas flow apparatus and the MTS815.02 system (MTS System Corporation, 1993) are two major components in the testing system.Fig. 3 is the photo of

Mechanical Properties of Grouted Crushed Coal with

To have a better understanding of the reinforcement effect on the crushed zone after grouting in coal mining extraction work, a selfdesigned grouting apparatus was used to study the effects of the grain size mixtures (distribution) and the stress state on the mechanical behaviours of grouted crushed coal specimens. From the various grouting Production and Use of Coal–Oil Granules SpringerLink,Coal–oil granules derived from finegrain coal sludge may be used to produce water–coal fuel suspension and coal–oil briquets. The fuel briquets obtained are characterized by adequate mechanical strength for subsequent transportation and fuel use.
