Abstract
A method for fracturing a solid material is disclosed. The method comprises boring at least one bore hole in the solid material, the bore hole having a bottom and an open top. Reactive materials capable of an exothermic reaction to produce a liquid and a gas are introduced into the bore hole. The bore hole is then sealed at the open top. The exothermic reaction is then initiated to produce the liquid and the gas. The pressures generated by the liquid and gas in the bore hole result in fracturing of the solid material.
