[Extract] Mining is one of the major export industries in Australia, and several other countries worldwide. As a result of mining operations, very large underground openings are created that are later backfilled to provide regional stability. The large underground voids that are backfilled are called stopes, and they can be approximated as rectangular prisms, which can be more than 100 m in depth. Backfilling is also seen as an effective means of disposing the by-products of the mineral processing called tailings that are left after the valuable minerals are extracted from the ore. There are several types of mine fills such as hydraulic fills, cemented hydraulic fills, paste fills, aggregate fills, cemented aggregate fills, and rock fills that are based on combinations of surface process tailings, and development waste or quarried rock. Hydraulic fills have often been considered as the conventional mine fill materials, primarily owing to their widespread usage throughout Australia: in Queensland, New South Wales, Tasmania, and Western Australia.
