Zusammenfassung:	Methods and configurable apparatuses for mining a vein using electrocrushing. The apparatus can be configured to match the size and shape of a vein, greatly reducing mining of the surrounding matrix and therefore the amount of material that is transported to the surface. The apparatus is modular, can be assembled underground, and can be propelled by retractable tractors. The apparatus is guided using a positioning and navigational system in accordance with the mine design. The apparatus can be steered by varying the pulse rates on different end effectors which produce the arc that fractures the vein, and sensors can minimize excavation of the surrounding matrix. The electrocrushing process produces cuttings that have already undergone the first stage of comminution to less than one inch in size, thus reducing operational costs. The apparatus can mine parallel slots in a vein, leaving support ribs in place between the slots.
