many industries. In coal mining, overexposure to respirable coal mine dust can lead to coal workers' pneumoconiosis (CWP). CWP is a lung disease that can be disabling and fatal in its most severe form. In addition, miners can be exposed to high levels of respirable silica dust, which can cause silicosis, another disabling and/or fatal lung ...

a case of "if" you will have a PRB coal fire, it's "when." Spontaneous combustion of coal is the process of self heating resulting eventually in its ignition without the application of external heat. It is caused by the oxidation of coal. If the rate of dissipation of heat is slow with respect to the evolution of heat by oxidation there will

Of the chemical agent fire suppression systems, ECARO-25 is the most cost-effective solution from an agent cost-per-pound basis. Because of its chemical properties and natural propensity to effectively fill a protected space, HFC-125 requires 10 percent less agent than does HFC-227ea, and 35 percent less agent than does non-brandd FK-5-1-12.

In view of this, a new dust suppressant for use in open-pit coal mines has been synthesized with graft copolymerization so that it has a cross-linked network structure. The main material selected in the experiment is soy protein isolate (SPI), which has abundant sources, low cost, and biodegradability (Wang et al. 2011 ; Lu et al. 2017 ).

Of the innumerable dangers facing coal miners every day, perhaps none is as omnipresent or potentially damaging as the outbreak of a fire. Underground or on the surface, the industry has learned the hard way to be ever vigilant. Between 1991 and 2000, there were 137 mine fires reported to MSHA, 76 of these were in underground coal mines.
