Simulation Services

Investments in mining involve large sums of money. Bad investments even more. The same is true when it comes to optimizing complex mining processes. In-depth understanding is needed to estimate the effect of a proposed change, or when verifying all variables in the existing process. Ideally, you want to know the effects of an investment or production change in advance. Simulation is a valuable management tool that is well suited to the study of mining processes, it is very effective and cost saving for mining projects in a feasibility stage, as well as for operating mines.

Simulation models allow engineers and mine operators to optimize the selection of equipment and other resources by evaluating alternative “what if” scenarios in the model, rather than during costly field trials.

Conventional analysis with a spreadsheet is static and must incorporate significant assumptions pertaining to equipment operating interferences and other delays that take place over time. The computer simulation model surpasses spreadsheet analysis by incorporating two key parameters; analysis over a period of time and statistically varied random and nonrandom events, such as breakdown maintenance and planned maintenance, to incorporate real-world interferences and delays in the model.

Computer animation of the model allows engineers and mine operators to view the dynamic production system as it operates, resulting in a far better understanding of the actual production system operation. Equipment interferences and delays can be visually examined for better understanding of the statistical results generated by the model itself.

Simulation is a powerful modeling tool that can be used to help reduce mine development and operating costs and saves time by optimizing the design of production facilities and the selection of production equipment.

A few examples of mining simulation services we can provide:

Haulage Strategies

Maximizing productivity and minimizing cost is essential for any mining operation. Haulage and hoisting systems are typically capital investments, which have a large impact on every mine´s productivity, operating cost and competitiveness. It is essential to identify the optimal solution by thoroughly analyse the pros and cons of every alternative solution prior to making an investment decision.

Maximizing productivity and minimizing cost is essential for any mining operation. Haulage and hoisting systems are typically capital investments, which have a large impact on every mine´s productivity, operating cost and competitiveness. It is essential to identify the optimal solution by thoroughly analyse the pros and cons of every alternative solution prior to making an investment decision.

By simulating the mine’s haulage system, a number of asset management issues can be investigated:

  • Equipment operating characteristics, such as loading and dumping times, traveling speeds, capacities, treatment rate etc, and variations for different types of materials handled.
  • Equipment maintenance parameters, including both planned maintenance and random breakdowns.
  • Interference between vehicles, and the capacity and spacing of passing areas for trucks or trains etc.
  • Existence and capacity of surge bins and stockpiles.
  • Characteristics of rock to be handled, such as patterns of “availability” of different rock types, “digability”, drawpoint hangup characteristics etc.

Development Strategies

Mine developments are capital investments, which need to be completed on time within budget. Vital resources, e g operators, jumbos, scoops and dumpers, need to be highly utilized in order to achieve the development rates that the mine demands. Drift advances and sequencing need to be carefully scheduled to avoid blockage and waiting time.

By simulating the mine’s developments, a number of asset management issues can be investigated:

  • Identifying bottlenecks, effects of purchasing/hiring additional equipment.
  • Development delays due to equipment downtime and effects of maintenance improvements.
  • Evaluate best shift schedules to meet development rate demands.
  • Identifying critical paths and critical start date in development projects.
  • Verifying development schedules
