What is the purpose of the fill in cut-and-fill mining?

To provide support for subsequent openings or to provide a working platform for further mining

In classic cut-and-fill mining, what is placed to create a new, higher working level?

Uncemented waste rock or hydraulically placed sand fill

What do raises in cut-and-fill mining provide?

Access up through the fill and occasionally down from upper levels

Which type of ore body is typically mined using cut-and-fill methods?

Relatively narrow and subvertical tabular ore body

What is an example of a method that may stand alone in cut-and-fill mining?

Drift-and-fill

Describe the process of classic cut-and-fill mining and the purpose of the fill material used in this method.

Classic cut-and-fill mining involves the successive mining of horizontal or inclined slices upward through a relatively narrow and subvertical tabular ore body. The fill material is used to provide support for subsequent openings or to create a new, higher working level to gain access to ore above and to support the ground below.

What are the potential applications of cut-and-fill methods in mining operations?

Cut-and-fill methods may be applied in conjunction with other conventional methods, such as blasthole stoping, or they may be methods that stand alone, such as drift-and-fill.

How are raises utilized in the context of cut-and-fill mining?

Raises maintained up through the fill (and occasionally down from upper levels) provide for access to different levels within the mine for ore extraction and ground support.

What is the purpose of placing uncemented waste rock or hydraulically placed sand fill in classic cut-and-fill mining?

The purpose is to create a new, higher working level to gain access to ore above and to support the ground below.

What is the defining characteristic of cut-and-fill mining and how does it differ from other mining methods?

The defining characteristic of cut-and-fill mining is that excavated voids are filled with barren material to facilitate the continuation of ore production. This sets it apart from mining methods that do not require backfilling of excavated voids.

Test your knowledge of cut-and-fill mining methods with this quiz. Explore the defining characteristics and applications of cut-and-fill mining, including the requirements for filling excavated voids and providing support for ore production.
