Holes can be produced in very hard rock more easily and less expensively by thermal spallation than by conventional means. This drilling process has been used for producing blast holes in the taconite iron mines and for quarrying granite. It is potentially valuable for drilling holes in very hard rock for the exploitation of geothermal energy and the storage of various commodities. However, investigation and development of the thermal spallation drilling process is proceeding slowly.
