There are now many proposed in-situ oil shale mining methods, but the principles of different in-situ oil shale mining technologies are similar. The general mining steps are as follows: First, the oil shale is fractured by injection of liquids at high pressure or high-temperature gas (Peng et al., 2018). This process not only increases the ...

Oil shale must be mined using either underground- or surface-mining methods. After excavation, the oil shale must undergo retorting . This is when the mined rock is exposed to the process of pyrolysis — applying extreme heat without the presence of oxygen to a substance, and producing a chemical change.

Oil-shale is one of the most important direct sources of hydrocarbon in southern China. The term "oil-shale" refers to organic-rich fine-grained rocks that produce oil upon distillation and has a production cut-off value, used to distinguish between oil-shale and marlstone, of greater than 12.5 litres per metric tonne. One of the largest oil-shale mining areas of China, and a major source …

The Rifle, Colorado, oil-shale project of the Bureau of Mines included three major divisions: (1) mining, (2) retorting, and (3) refining. The major functions of the mining program were to supply oil shale to the retorts, to devise mining procedures, and to develop an underground-mining method by which oil shale could be produced safely at an unusually low cost per ton.
