Book excerpt: Excerpt from Problem Sites: Lands Affected by Underground Mining for Coal in Illinois Early coal mining in Illinois consisted of digging in outcrops along river bluffs or stripping shallow overburden from seams near the surface. Such techniques resulted in very little refuse (waste coal and other debris) at the surface, as most coal was selected by hand without further processing. Modern mining practices incorporating continuous mining machines, as well as the demand for clean, processed coal, has resulted in current refuse rates of 20 to 50 percent of the deep mined coal. In 1974, the nation's coal industry generated about 130 million tons of coal mine refuse (schlick and Wahler Refuse produced by underground mines in Illinois totaled an estimated 8 to 15 million tons in 1975, or approximately million cubic yards. Coal preparation plants produce two types of refuse material gob and slurry. Coarse refuse (plus 28 sieve or referred to as gob, contains waste coal, rock, pyrites, or other materials of relatively large size. The washing process produces effluent (minus 28 sieve), referred to as slurry, containing small coal particles, clay, and other debris (martin In the past, gob was deposited in refuse piles; slurry was pumped and deposited into streams, onto adjacent terrestrial areas, or into impoundments.
