It ordinarily occurs with galena and is a major ore of zinc. The iron sulfide pyrite (FeS), which is also called fool's gold, is common in nearly all types of rocks. It is the weathering of this mineral that leads to acid-mine drainage, which is common in many coal fields and metal sulfide mining regions.

Phase I Cut and Fill University of Georgia

So, the cut and fill process is typically one of the first construction processes to take place on a site. Without computer software to determine the amount of land to be added or removed, we can do simple calculations to estimate the cut and fill volume of any site. First, the site is divided into sections.

How Underground Mining Works Science HowStuffWorks

This method can be used in wider deposits, as well, by drilling two adjacent access ramps and cutting two adjacent drifts, often called drift and fill . Cut and fill is for hard rock, as it doesn't feature the support mechanisms inherent in and central to a method like room and pillar.

Tailingsfo Backfill of Tailings to Underground Workings

Dry rock fill is rock waste, surface sands, gravels, or dried tailings. The fill is either dropped down a raise, or tipped into an open stope by a Load Haul Dump (LHD) or dump trucks. Dry rock fill is most suited for the cut and fill mining method.

Room and pillar is a method of underground mining that involves excavating rooms with pillars that hold up the roof and is used for shallow mines. In block caving, miners drill tunnels underneath the ore deposits and then draw the material down. In the cut-and-fill method, miners work in horizontal slices underneath the surface, and the
