Book Description
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.

Book Description
Excerpt from Hydrogeologic Aspects of Coal Mining in Illinois: An Overview Progressive drainage and rewetting during mining may weaken the mine roof and floor materials, and repeated wetting and drying could further weaken the rocks. For example, in the city of Streator, Illinois, sewage has been dumped into the old mine workings for many years and allowed to move later ally through the workings, discharging to the Vermilion River. Current studies undertaken to control the sewage discharge suggest that repeated wetting and drying will significantly reduce the strength of the rocks and therefore increase the incidences of mine subsidence. Thus, any change in the hydrogeologic regime of a mine, such as backfilling a dry mine with water (man-induced or natural) or pumping water from a mine which has filled, may weaken the rocks and precipitate increased rates of subsidence and sur face damage. Severe inundation does not occur in most deep coal mines in Illinois, and the depletion and drainage of aquifers in mine dewatering operations is generally not a problem. In areas of Illinois in which the Pennsylvanian series is the uppermost bedrock unit, the ground water becomes mineralized at an average depth of less than 100 meters (about 300 ft). Most Illinois coal mines are in bedrock which contains mineralized water. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Surface Subsidence in Illinois Resulting From Coal Mining It is undoubtedly to the interest of the State to conserve the coal supply by securing as complete extraction as possible from the areas in which mining is now being carried on. Almost one - half of the coal is being left in the ground and made unavailable for future mining, and in some places a large part of this abandoned coal is left because the mine operators fear that by removing a larger per centage they may cause surface subsidence and be required to pay damages out of proportion to the real value of the surface. In many places the surface may be restored at little expense. But until the prevailing conditions are known accurately and the essential facts are understood and studied, the State cannot consider or propose meas ures to relieve the mining industry of this severe burden.
