MINING METHOD OF THE WEEK - CUT AND FILL MINING!!

    This type of mining is typically done upwards from lower levels, so the fill is also used to provide a new working level for further mining. Cut and fill mining can be expensive, but this method allows for highly selective mining with less waste rock or low-grade ores mined-out (which keeps production costs low).

    Definition of selective mining - Mindat

    Selective methods of stoping are square-set stoping, open stoping in low-dipping beds, and cut-and-fill stoping. iii. In coal mining, selective methods may be dictated by market demands and prices. It may be desirable to work the different quality coal seams in such proportions as to obtain a uniform and salable blend over a period of years.

    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.
