Physical, mechanical, and hydraulic properties of coal
ABSTRACT: Coal mining processes result in two general types of byproducts: coarse coal refuse (CCR), a mixture of soil and rock commonly used to construct an impoundment coal refuse dam or embankment, and fine coal refuse (FCR) slurry, a mixture of soil, rock dust, coal fines and water that is pumped into such an impoundment.
Weathering is the physical breakdown and chemical
recognized: mechanical and chemical. Both proceed at the same • The acid mine drainage so common in coal mining areas is produced by oxidation of pyrite (FeS 2), a mineral common in In this way clay minerals, which are sheet silies, are formed from framework silies such as feldspars.

5.2 Chemical Weathering – Physical Geology opentextbc.ca
There are two main types of chemical weathering. On the one hand, some minerals become altered to other minerals. For example, feldspar is altered — by hydrolysis — to clay minerals. On the other hand, some minerals dissolve completely, and their components go into solution. For example, calcite (CaCO 3) is soluble in acidic solutions.

PennsylvaniaMines Mining Artifacts
In 1926 mining began in the second ore deposit, and the Bethlehem Steel Corporation gained sole ownership of both deposits to supply ore to its steel mills. Mining continued until 1973 when Tropical Storm Agnes filled the mine with water. Engineers determined that the value of the remaining ore was not worth the cost of draining the mine.

Clay is a finelygrained natural rock or soil material that combines one or more clay minerals with possible traces of quartz (SiO 2), metal oxides (Al 2 O 3, MgO etc.) and organic matter. Geologic clay deposits are mostly composed of phyllosilie minerals containing variable amounts of water trapped in the mineral structure.
