摘要： Process and apparatus is described for mining of subterranean carbonaceous deposits such as tar sands, in which the deposit is treated in situ with circulating high pressure jets of heated mining fluid comprising water in admixture with gaseous hydrocarbons, or carbon dioxide and the deposit is also subjected substantially simultaneously to mechanical grinding in the vicinity of application of the circulating jets, so as to free and grind the deposit and float the separated carbonaceous portion to the surface. The mining tool has an umbrella-like action, comprising a plurality of mining arms carrying jets and potatable mining teeth or cutters, the tool being rotatable down hole to mine the deposit, and the mining arms thereof being radially expandable below ground, so as to enlarge a pilot hole drilled initially, into a large production hole for large scale mining projects.
