GEOTECHNICAL CHARACTERISTICS OF COAL MINE SPOIL

GEOTECHNICAL CHARACTERISTICS OF COAL MINE SPOIL FITYUS et al. A "point count" identification of rock types was carried out on 100 fragments (6.7 mm-9.6 mm) from each prepared bulk sample. The compositions of each sample are summarised as: 'coarse' 50% sandstone, 20% conglomerate, 24% mudrocks, 5% chert and 1% coal.

broad particle size distribution (Carras et al, 1994). In addition the material distribution in spoil piles depends on the nature of the strata before mining, as well as the method of mining and dumping with each mining method resulting in a different overall layering or mixing of the materials.

Mine spoil waste Most human extractions of earth materials, such as clay for pottery or coal for power generation, produce some waste. The raw materials are rarely pure, so unwanted detritus is discarded, usually close to the extraction site. Over the last two centuries, exponential industrial growth has resulted in huge increases in the production of mine spoil waste.

A spoil tip (also called a spoil bank, boney pile, gob pile, bing, batch or pit heap) is a pile built of accumulated spoil - the overburden or other waste rock removed during coal and ore mining.These waste materials are typically composed of shale, as well as smaller quantities of carboniferous sandstone and various other residues. Spoil tips are not formed of slag, but in some areas they are .

A by-product of sand mining that is used in sand mine restoration is spoil. Spoil is a mixture of unwanted sand grain sizes and small amounts of impurities, such as organic matter and is typically spread over the disturbed areas prior to restoration of a sand mine site (A.
