Underground Mine Backfilling in Australia Using Paste Fills …

Underground mine backfilling is a form of ground improvement that has to be carried out in the mine sites.

Backfill is commonly used as mine support. For example, in South Africa it is used for regional and local support in deep gold mine stopes. It is also used in shallow operations to enable multi-reef extraction (see e.g. Squelch, 1993; Ryder and Jager, 1999). There is a vast amount of literature available on backfill and the types of

Backfill basics

A. Backfill will play a vital role in the extraction process of ore in deep mining. It just takes more effort to install pipelines that reach down to the 7,000 to 10,000- foot level. Basically, fourth-fifths of mining is at the deep level. Other countries such as South Africa are beyond the 12,000-foot level.
