Crushed coal, consisting of a wide range of sizes, was effectively blended by recycling it through a bin equipped with a particle distributor. Vertical blending was accomplished by simply recycling the coal; it was not significantly influenced by the horizontal blending that was achieved by the distributor. The method was effective, even though the coal was wet and possessed poor flowing charact

New Insights of Grouting in Coal Mass: From Small-Scale ...

The "coal-grout interface layer" can be seen as an intermediate layer filled with crushed coal between the grout layer and a relatively stable coal layer. When the coal-grout structure suffered high stress, the irregularly cracked interface layer failed easily, which induced the stress drop and affected the overall stability of grouted coal.

Coal

Brown coal is crushed to < 8mm coal and combined with up to 5% water. The mixture is fed into an :"Attritioner" that rubs the coal faces together. The heat generated triggers an exothermic reaction which in turn triggers a "natural reaction that expels water from the coal" . The now plasticised coal …
