Manganese is the third most common constituent of steel. Annual global production of metallic manganese exceeded 13 million tonnes in 2013, with over 90% of mined manganese ores consumed by steelmaking. The remainder is used in applications such as batteries, fertilizers, catalysts, pigments and non-ferrous alloys [1–3].

Most underground mining of the manganese is generally done by room and pillar method. Mining at Nchwaning and Gloria mines uses two shafts when it was initiated in 1981, one vertical hoisting shaft that is 450m deep and another vertical shaft. Now further rooms and pillar rooms are made with low grade ore for easier mining.
