A method for mining a mineral deposit underground in a vein having an underburden and an overburden which comprises boring a pilot hole into the vein between the underburden and the overburden. The thickness of the material is then measured at predetermined distances along the pilot hole, between the pilot hole and the overburden, and between the pilot hole and the underburden. The information measured is stored in a storage mechanism which relates the measurements to the distance in the borehole. A mining machine is then controlled in accordance with the distance between the borehole and the overburden, and the borehole and the underburden. |
