Micro-structure of crushed coal with different metamorphic

8/1/2020· After the coal is crushed to 0.180−0.224 mm, the crushing process begins to exert a weaker effect on the consumption of aliphatic hydrocarbon groups. For the −OH group, the slight increase in the range of 0.180−0.280 mm almost never occurs in the low-rank lignite but is present in bituminous coal and anthracite.

Sources of underground CO: Crushing and ambient

11/1/2015· Experimental results indicated that in the air atmosphere, coal sample mechanically crushed in a sealed tank generated CO. The CO generation process is similar to underground coal cutting process with coal shearer. The result can indirectly verify whether coal crushing is an important source of CO generation. 3.1.1.
