ABSTRACT: Mechanized Oil-Shale Mining in Southern China ...

Mine drill-holes, to test the extent of the oil-shale, have een drilled to a depth of 1000 m and still swabbed oil from oil-shale. The mine was started in 1958 on an automated schedule using power-shovels, hoppers, and electric trains. Present-day excavation continues at a rate of approximately 10 m per year cutback of the mine face.

The Oil Drum An echoing Shhh, or more on mining of oil shale

2006-6-28  Using a machine to mine the oil shale poses some problems, since it is much stronger than, for example, the tar sands of Alberta, that can be scooped up with a shovel. Rather the rock has a strength that decreases with oil content down to about 13,000 psi with an oil grade of 30 gal/ton , at which point it stabilizes even as the grade increases.
