MINING METHOD OF THE WEEK
07/09/2018This 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).

Reliability analysis and design of backfill in a cut
The mining method known as cut-and-fill, which incorporates backfilling in its operational cycle, is ranked as a major method of underground mining. Even the room-and-pillar mining and sublevel stoping methods also employ backfills such that the remnant pillars can be recovered after the primary mining operations have been completed.

Cut and fill is a very expensive method, but is very selective. You might predict the type of deposits in which it would be employed as the principal mining method. High value metalliferous ores such as gold or silver are often mined by this, and when the high-grade ore is in veins, the high degree of selectivity of this method is a real asset.

How to Calculate Cut and Fill for Earthworks Projects
06/09/2017The cut or fill depth for each cell is found by subtracting the average existing level of the cell from the average proposed level. If the resultant depth is positive then this is a fill cell, while a negative value indicates a cut cell. In either case, the volume is calculated by multiplying the cut or fill depth by the area of the grid cell.
