Miner's Black Lung disease is called silicosis but has nothing to do with silica....it is caused by coal (carbon) dust. Black lung is a legal term describing a preventable, occupational lung disease that is contracted by prolonged breathing of coal mine dust. Described by a variety of names, including miner's asthma, silicosis, coal workers' pneumoconiosis, and black lung, they are all dust diseases with the same symptoms. umwa.org Footnote: My father worked in the anthracite mines for more than 40 years starting as a breaker boy at 8 yrs old............had his first heart attack in his 40's.. If not, then the silica sand producing companies and workers aren't part of the drilling industry .... after all, the silica sand producers aren't drilling oil and gas wells and fracing them. They're just producing a product the drillers use, like the silica miners and workers who produce the silica used to make the silicon used in solar panels. Agreed the silica producers aren't part of the drilling business.... But silicon producers are part of the solar cell business....but not silica producers.
