This is the classic method for mining narrow orebodies and involves extracting the ore in small slices, 2 to 4m high, working from the bottom upwards. As each cut is extracted, the void is filled, primarily to form a working platform for the next lift.

Classification of Underground Mining Methods Mineral production in which all extracting operations are conducted beneath the ground surface is termed underground mining. Underground mining methods are usually employed when the depth of the deposit and/or the waste to ore ratio (stripping ratio) are too great,How Underground Mining Works | HowStuffWorks,Underground mines are the alternative to surface mines. Surface mines excavate from the top down, a method that can become inefficient at depths greater than about 200 feet (60 meters) [sources: Illinois Coal Association, De Beers].Undergrounds coal mines can drive 2,500 feet (750 meters) into the Earth and other types even deeper -- uranium mines can reach 6,500 feet, or 2 kilometers.
