Marissa: All mining is dangerous but coal mining has particular safety issues that must be contended with. Coal mining releases methane, known to the miners as "firedamp," which is highly explosive under certain concentrations. Coal dust was even more dangerous, which could cause an explosion that could be triggered by firedamp …

Effective risk prevention and management in deep coal mines can reduce the occurrences of outburst accidents and casualties. To address the low accuracy and inefficiency of coal–gas outburst prediction in deep coal mines, this study proposes a deep coal–gas outburst risk prediction method based on kernal principal component analysis …
What Is Coal Preparation? • Coal preparation is the removal of undesirable material from the Run-of-Mine (ROM) coal by employing separation processes which are able to differentiate between the physical and surface properties of the coal and the impurities. Through coal preparation, a uniform product is achieved.
