Coal gangue is a mixture of carbonaceous, argillaceous and sandy shale. The main chemical components are SiO 2 (about 46.7%), Al 2 O 3 (about 15.45%), and a small amount of CaO, Fe 2 O 3 and other metal oxides [9].These chemical and mineral properties similar to natural aggregates (NA) make it possible to use coal gangue as aggregate to prepare concrete [10].
The first comminution stage in a mineral processing plant is crushing, which reduces the size of particles from up to 1 m down to 0.5 cm (depending on the type of milling circuit). Crushing is typically a dry process that makes use of Gyratory, Jaw, and Cone crushers (Napier-Munn et al., 1996), which predominantly make use of impact mechanism.
The course of coal and gas outburst is also a procedure of rapid release of gas internal doublerun drill energy and coal crushing and throwing.

Because most coal breaks up readily during mining, it requires only minor crushing to break it down to a manageable size for handling, with the top size of around 5 to10 cm. hence coal plates don't require multiple stages of crushing and grinding to grind the coal down to fine powder, as is done with most mineral processing.
