ABSTRACT:
The invention is directed to a method of in situ extraction of a constituent of a rock formation, e.g., copper deposits or particular petroleum deposits as found in oil shale, and to a method of preparing the rock formation for in situ extraction of the rock constituent. Various embodiments of a side excavating machine are also disclosed for preparing the rock for in-situ extraction of a constituent therefrom. The excavating machine breaks the rock in-situ in a manner to form a narrow, horizontal flow-directing chamber in the rock-filled with fluid-permeable broken rock.
