Mine Planning (Dragline) – Brisbane

Dragline mine design

Systematic mine planning process, and mining limit assessment using economic ranking criteria.

Dragline key components

Typical configuration, dig & dump cycle, understanding dragline working envelope, and dragline buckets.

Dragline operating methods

Range diagrams, pit layout, boxcuts, single seam applications, multi-seam applications, use of dozers & throw blasting, handling geotechnical & hydrological issues.

Dragline productivity

Calculating re-handle, productivity calculations, sensitivity to changing operating & design paramaters (pit width / seam dip / swell / ramp placement etc), motion control & new technology, sensitivity to operators &
design procedures.

Dragline scheduling

Meeting production targets, blending constraints, and dragline sequencing.

Economics & decision making

Evaluation techniques, marginal cost analysis, time value of money, and discounted average cost.
