Abstract
The Bureau of Mines has developed and tested a thermohydraulic method for hard rock kerfing and excavation. Heating induces structural weakness and subsurface damage in rocks and assists fragmentation by water jet impingement. Laboratory and field test results show that this novel combination method overcomes cuttability limitations of the thermal energy process in hard rocks.
