Generating ore and waste block model

The first stage in mine planning and scheduling is providing a block model of ore and waste, appropriate for pit optimization studies. Blocks in the generated model should be separated base on: rock type, processing method, mining condition and geotechnical parameters.

Providing economic model of ore and hosting rocks

Within this stage, by assigning economic parameters to each block, the geological model is converted to an economic model. The economic parameters comprise: sale price, mining and processing costs and recoveries in each stage.

Surface/Underground mining limit

Since the economic model was provided, outlines for ultimate and optimal pit can be determined by utilizing NPV Scheduler, a powerful pit optimization and mining scheduling software. The engineered pit will be designed based on these outlines.

Mine planning

Can be divided to: open casting and underground mining.

Underground mine planning

Includes:

• Selection of mining method
• Mining passports
• Mine openings
• Underground haulage system
• Support or control of excavated area
• Drilling and blasting patterns
• Ventilation plans
• Mining scheduling
• Utilities such as: compressed air, drainage, lighting and …

Surface mine planning

Includes:

• Pit optimization
• Pushback generation
• Long term and short term scheduling
• Stockpile optimization
• Haulage distance optimization

Optimizing production capacity

In order to achieve the maximum NPV, production capacity should be optimized

Mining scheduling

Mining schedule will be optimized for surface and underground mining methods.

Mining machinery

Mining machineries will be selected with respect to mining capacity, in the other word; geometrical parameters in open pit and opening dimension in underground mind ought to be selected considering dimensions of mining machineries.

Contracting and project management

• Providing tender documents based on MPO instructions
• Providing general and particular conditions of contracts (GCC & PCC)
• Providing technical documents
• Providing lists of required machineries and equipments in projects
• Cost estimation and financial appraisal
• Holding bids and contracts
• Supervision and management of projects.
