Two methods for mining oil shale

oil shale is mined by underground or surface mining methods. In Colorado and Utah underground room and pillar mines were opened decades ago and are still in stable condition. Because of the strength of the oil shale beds, large stable rooms can be created supported only by pillars of oil shale and rock bolts placed in the ceiling. Mining Oil Shale Oil shale can be mined using one of two methods: underground mining, most likely using the room-and-pillar method, or surface mining. In general, surface mining is the most efficient approach for mining oil shale. Room-and-pillar mining can recover about 60 percent of the oil shale in place for seams that are no more than about a Commercial grades of oil shale, as determined by their yield of shale oil, ranges from about 100 to 200 liters per metric ton (l/t) of rock. The U.S. Geological Survey has used a lower limit of about 40 l/t for classification of Federal oil-shale lands. Others have suggested a limit as low as 25 l/t.

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.. The most common method of extracting shale oil is by surface mining. The in situ combustion process is used for extracting shale oil from far below the surface. The extracted shale oil then undergoes pyrolysis at 842 to 932°F (450 to 500°C) to produce oil shale (synthetic crude oil), shale gas and residue (solid). Answer to Which of the following is one of the two methods for mining oil shale? Two methods have been developed to extract petroleum products from oil shale. One is to mine it like the rock it is, and then heat it in the low-oxygen environment needed to turn the kerogen into oil and gas. Which of the following is one of the two methods for mining oil shale? strip mining Plant-based organic matter that is compressed under high pressure to form solid carbon structures is known as __________.

What is Hubbert's peak? a prediction, based on rates of extraction and new discovery, of when a country's or global oil production will be at a There are two known ways to make oil out of oil shale, and only one of these — using traditional mining and refining techniques — is proven. Enefit has decades of experience using conventional mining and processing techniques to produce oil in its home country of Estonia.

16.4 Methods of oil shale utilization. The following are the methods of development of oil shale deposits as a solid fuel. The choice of mining method is determined by the depth of the oil shale seam below the surface. Opencast mining is a cost-effective and productive solution. It poses little or no hazard to miners.
