Read More2020-3-1 The presence of mineral matter in coal may result in a number of environmental and human health problems related to its mining. During coal mining activities, large quantities of coal dust, ashes, and heavy metals are released into the environment, forming a complex mixture (Mejía et al., 2016). Briefly, air pollution occurs due to blasting ...
