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

In this selective mining method, the void created by mining is backfilled with a mixture of waste rock or tailings (with cement sometimes added to strengthen the mixture), which helps support the walls of the empty space. 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). It’s typically used in situations where the ore body dips steeply or is very irregular, which makes mechanized long-hole methods difficult to implement - New Pacific Metals Corp.
