This accounts for roughly 10 % of the world's whole crude oil reserves. The previous-faculty strategy of blast mining, that makes use of explosives like TNT to interrupt up ore, is still in use, but just barely - less than 5 percent of U.S. The longwall technique can recuperate up to ninety % of the accessible ore.
