The underground mining methods we use include room and pillar, narrow vein stoping and large scale mechanised mining Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds We use this for mining coal

ASSESSMENT OF SAFE MECHANISED DEPILLARING METHODS FOR ANJAN HILL, CHIRIMIRI COLLIERY SOUTH EASTERN COALFIELDS LTD INDIA OCTOBER 2002 Prepared by Jaco J van Vuuren The pillars in the zero seam were not designed with pillar extraction by modern mining methods in mind and the size of the pillars do not correspond well with the extraction

Selective mining methods Cut and fill mining is a method of short hole mining used in steeply dipping or irregular ore zones, in particular where the hanging wall limits the use of long hole methods The ore is mined in horizontal or slightly inclined slices, and then filled with waste rock, sand or tailings
