· Rock bolts or yieldable steel arches are fit for stable rocks; combined supports with steel arches, rock bolts and cables, are necessary for the instable rocks. Most roadways in German coal mines have an arch crosssection (except openoff cuts with a rectangular shape) with a large crosssection area about 30 m 2 .

· Ultrasonic vibration gassolid fluidized bed was proposed and introduced to separate fine coals (– mm fraction). Several technological methods such as XRF, XRD, XPS, and EPMA were used to study the composition of heavy products to evaluate the separation effect. Results show that the ultrasonic vibration force field strengthens the particle separation process based on density .
· Dense medium separation (or heavy medium separation (HMS), or the sinkandfloat process) is applied to the preconcentration of minerals, the rejection of gangue prior to grinding for final liberation. It is also used in coal preparation to produce a commercially graded endproduct, clean coal being separated from the heavier shale or ...
· Coal is a black or brownishblack sedimentary rock that can be burned for fuel and used to generate is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel in the United States.
The biggest coal deposit by volume is the Powder River Basin in Wyoming and Montana, which the USGS estimated to have trillion short tons of inplace coal resources, 162 billion short tons of recoverable coal resources, and 25 billion short tons of economic coal resources (also called reserves) in .

· Paleochannels are sedimentary rock units deposited by ancient streams that transported sediment through the peat mire. As discussed in the section on Coal Depositional Systems, paleochannels constitute the framework facies that bound the mire. The most adverse impact of a paleochannel is their potential to fully erode a coal seam (Picture 1).

coal coal Structure and properties of coal: The plant material from which coal is derived is composed of a complex mixture of organic compounds, including cellulose, lignin, fats, waxes, and tannins. As peat formation and coalifiion proceed, these compounds, which have more or less open structures, are broken down, and new compounds—primarily aromatic (benzenelike) and .
Vorsyl Separator Used in many coalpreparation plants. Treatment of small coal sizes up to about 50 mm at feed rates of up to 120t/h. The feed to the separator, consisting of de slimed raw coal, with the separating medium of magnetite. Material of specific gravity less than that of the medium passes into the clean coal outlet Heavier shale particles move to the wall of the vessel due to the ...

Here at SIU, we have the only densitygradient centrifugation lab in the country dedied to separating out individual macerals from coals and source rocks. These density separates are then used to better understand maceral geochemistry (including isotopic composition), as well as how organic materials respond to various processes (, gasifiion, oxidative hydrothermal dissolution, or OHD).
