Numerical and Experimental Study on Crushing Properties
The reserves of high-quality coal seams have been greatly reduced in recent years, and the low efficiency of traditional cutting methods in hard coal seams has become a problem for the coal production industry. In order to improve the mining efficiency, an impacting-cutting technique was proposed in this study. A drum modification model with picks impact function was established,

Coal Properties, Formation, Occurrence and Uses
Knowing the physical properties of coal is important in the preparation and use of coal. For example, coal density ranges from about 1.1 to about 1.5 megagrams per cubic metre, or grams per cubic centimeter. Coal is slightly denser than water and significantly less dense than most rocks and mineral matter.

Coal Types, Uses and Formation
Peat This type of coal has less than 40% to 50% of carbon, while the remaining is moisture. This makes it difficult for us to ignite and cannot be easily used. Lignite This type of coal has 40% 55% carbon content, which implies that moisture content is lesser than the peat variant. This is mainly used in households for cooking and ironing
