Conventional mining vs surface miners

 · Significant advantages emerged when working with the surface miner, which produced 14% fewer fines at grain sizes of less than 2mm compared to the conventional mining system. The portion of fines to be processed dropped by 22% at grain sizes of less than 1mm and even by 36% at grain sizes of less than 0.5mm.

What Is Oil Shale Mining? | iMINCO

 · Oil shale can be mined above and underground, crushed and then transported to a retort where it is heated to a high temperature, and the oil collected in a distiller. This results in an oil similar to that pumped up from conventional underground wells, but the process is more complex and therefore, more expensive at the present time.

Oil Shale

Oil shale can be mined using one of two methods: underground mining using the room-and-pillar method or surface mining. After mining, the oil shale is transported to a facility for retorting, a heating process that separates the oil fractions of oil shale from the mineral fraction.

Oil Shale Deposits | Maps, Geology & Resources

 · A deposit of oil shale having economic potential is generally one that is at or near enough to the surface to be developed by open-pit or conventional underground mining or by in-situ methods. Oil shales range widely in organic content and oil yield.

The difference between shale, coal seam, and conventional …

 · A conventional well simply involves drilling down, perforating, and letting the gas flow. Because it doesn''t involve de-watering or hydraulic fracturing, it''s thought to be safer than CSG or shale — but CSG and shale drilling exist in part because all the …

Oil shale industry

Oil shale is mined either by traditional underground mining or surface mining techniques. There are several mining methods available, but the common aim of all these methods is to fragment the oil shale deposits in order to enable the transport of shale fragments to a power plant or retorting facility.

Shale Oil

Mining oil shale can be either surface mining or in situ retorting. In surface mining the oil shale is transported to aboveground facilities. There the oil shale is crushed and loaded into a reactor known as a retort, where the temperature is increased to about 400–500°C to decompose the kerogen and release the shale oil.

Oil Shale

Oil shale, despite the name, does not actually contain oil, but rather a type of organic matter called kerogen, a precursor of oil that is converted to a type of crude oil when heated to about 450 – 500° C. The oil shale deposits are in three structural and sedimentary basins that have been recently assessed:

Conventional vs unconventional resource

Conventional resources and unconventional resources are two very different, separate sets of resources that can potentially be extracted. Both refer to some quantity of fossil fuels that could contribute to a reserve if they could be extracted economically.The distinction between a resource and reserve is explored with a diagram known as a McKelvey box.

OIL SHALE

The unconventional shale oil resource can be transformed into liquid hydrocarbons by mining, crushing, heating, processing and refining, or by in situ heating, oil extraction and refining. One tonne of commercial grade oil shale may yield from about 100 to 200 litres (L) of oil, that is approximately a half to one barrel of shale oil per tonne of oil shale.
