This model was originally developed for one of the majors during a capital recommendation study which compared Electric rope shovels with Hydraulic excavators in open-pit coal mining operations.

CLIENT SPECIFIC REQUIREMENTS

 

Shovel comparison to address all aspects pertaining to:

 

●  Technical considerations.

●  Machine operation.

●  Digging and loading methods.

●  Productivity.

●  Commercial (Opex & Capex)

●  Environmental impact.

●  Geology and deposit characterisation.

 

ADDITIONAL REQUIREMENTS

 

●  Double-sided loading benefits.

●  MARC and Owner maintenance cost comparisons.

●  Trucking requirements - as per the existing fleet.

 

DATA INPUTS AND RESULTS

 

●  Geological models, mine engineering and designs, production schedules, existing equipment employed.

●  OEM: Equipment capital, Lifecycle Costing and MARC costs.

●  Results imported into Client's financial model.

●  Results applied for board recommendations.

●  Production schedules, budget forecasts.

●  Double sided loading costs, methods, designs.

 

DELIVERABLES

 

●  Operating temperatures, ground pressures, machine weight, power selection.

●  Bench heights, material layer digging, selective digging, drilling and blasting requirements.

●  Loading cycle times, debris removal, reach, pit floors, rock handling.

●  Maintenance costs, component replacement, ease of maintenance.

●  Capital costs, unit costs, machine life, fuel costs.

●  Process procedures, double sided loading.

 

IMPLEMENTATION

 

●  Project lifecycle - 15 years

●  Tacmin assistance – recommendations, mine designs, project implementation.
