Surface gas handling and mud gas separator design principles

A Vertical separator is normally used for high fluid throughput, while a horizontal separator provides a longer retention time and superior gas separating capacity. Internal design and configuration (e.g. blast chamber, baffle plate etc.) governs the individual efficiency of the

Blasting is required and blast patterns are laid out according to material type using rock type designations of hard, average, soft, or combinations of all three. The pit design varies between 6.1 metre to 12.2 metre (20 to 40 ft) benches and, where possible, up to 18.3 metre (60 ft) benches in the ore, though mined in 6.1 metre (20 ft) cuts.

Comminution (i.e., the breaking of rock to facilitate the separation of ore minerals from waste) combines blasting (a unit process of mining) with crushing and grinding (processing steps). In-situ mining, which is treated under a separate heading in this chapter, is a special case that combines aspects of mining and processing but does not
