the 1969 federal coal mine health and safety act established environmental dust standards for underground coal mines. the act requires that the average concentration of respirable dust in the active workings of a mine be maintained at or below 3.0 mg; and, that effective december 30, 1972, the 3.0 mg standard be reduced to 2.0 mg.blasting in coal mines modern mechanised coal mines use machines and longwall mining methods to cut solid coal and convey the broken coal out of underground workings. continuous mining equipment has escalated coal production and introduced more effective and efficient coal handling facilities.
