10-03-2018· Cut-and-fill allows selective mining and separate recovery of high grade sections and is therefore useful for ore bodies with irregular shapes and scattered minerals. Compared to other mining methods, room-and-pillar mining is a low-cost method with a low recovery rate (since some ore is left behind in pillars).

CA2062077A1 Selective mining method and apparatus

ABSTRACT The method is used in the selective recovery of ore-bearing reef from arock mass in a mine. The method involves forming spaced apart access gullies in the rock mass, the gullies extending in the direction of mining. A wire saw is then used to form cuts in the rock mass, the cuts extending between the gullies and being situated just above and just below the reef.

ABSTRACT. Selecting the best mining method among many alternatives is a multicriteria decision making problem. The aim of this paper is to demonstrate the implementation of an integrated approach that employs AHP and PROMETHEE together for selecting the most suitable mining method for the "Coka Marin" underground mine in Serbia.

Mining Underground mining Britannica

Mining Mining Underground mining: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of material mined, are much higher underground than on the
