Underground Crusher Selection and Design

2021-7-12  Typically in underground operations the crusher feed is not coarse and lumpy as in an open pit and is usually passed over a grizzly before crushing. It would take some special circumstances to justify the additional excavation required, additional equipment cost and more difficult maintenance.

2019-6-28  The location of the crusher has to be determined in an early design stage, since it has a great impact on the other steps in the mine design. For underground crushing, three stages of material handling are defined: pre-crushing, crushing, and post-crushing. The pre-crushing stage prepares the material for the crusher.

Ground behaviour analysis, support system design

2020-2-1  The results of the design of ground support system at some deep underground mines in Western Australia are summarised in Table 6. The loading factor (σ cm / σ 1), where σ cm is between 50 MPa and 120 MPa, and σ 1 is about 40–70 MPa, is between 0.9 and 2.3. Therefore, the rock mass structures have the potential to suddenly fail.

Underground Mining Transportation & Haulage

2017-4-1  The average haulage and hoisting costs for these groups ranged from $0.1135 to $0.4025 per ton of ore mined, and the range for 47 individual mines was from $0,086 to $1,848. Elsing has tabulated transportation costs at 66 mines, which show averages by groups ranging from $0,120 per ton mined to $0,556. It is therefore apparent that underground
