Wide range of services at your disposal

Choose mine planning from thyssenkrupp and you profit from consulting services for multiple topics throughout the mine planning cycle. We can conduct scoping and feasibility studies on your behalf or support such studies if you carry them out. We utilize a wide variety of externally and in-house developed solutions for tasks ranging from soil and rock testing to mine design, equipment dimensioning, mine scheduling, and we can also provide you with cost estimates, financial modeling, and sensitivity or risk analyses.

Close cooperation to maximize your success

Our mine planners – highly skilled plant engineers and mining professionals – will work directly with your project team to maximize your project’s success. Though our particular strength is in continuous mining equipment operations, we have access to a large database of equipment designs and mining concepts through thyssenkrupp Mining Technologies’ extensive project experience. This enables us to estimate prices fast and evaluate the applicability of integrated mining system concepts to facilitate your mining equipment selection. In addition, we develop detailed mining equipment specifications that allow immediate tendering and supply of the equipment specified.

Our services – your added value

Every project is unique and requires a different level of detail that mainly depends on the work already done. For that reason, each study follows a general methodology, or parts of it, as a standalone to enable a trade-off through comparing discontinuous truck and shovel systems with various continuous mining systems.

Every study requires a kick-off meeting, either remotely or at the project site, in order to base the project on sound foundations. The aim of the meeting is to collect and verify basic data, and confirm the scope of work and KPIs to be generated. If data is unavailable, equipment-specific material tests will be performed using hardness and abrasiveness evaluation techniques developed in-house.

The concept development phase investigates the general possibilities to operate a continuous mining system. Continuous systems use conveyors as the main means of transport. The use of such systems can lead to trucks being partially or entirely substituted. The main conveying systems available are in-pit mine conveyors, cross-pit conveying systems, mobile bridges/ grasshopper conveyors, high-angle conveyors, and ex-pit overland conveyors. The systems to be considered are:

  • Bucket-wheel excavator systems (BWE)
  • Fully mobile in-pit crushing on conveying systems (FM-IPCC)
  • Semi-mobile in-pit crushing onconveying systems (SM-IPCC)
  • Waste dumping systems
  • Heap leaching systems

As continuous mining systems are less flexible, the mine design must be tailored to the requirements of the system. This means that an appropriate and proven methodology for truck and shovel mining is inappropriate for continuous mining systems. To overcome this challenge, we established close working relationships with our customers and developed our own methodologies for planning continuous mining systems.

As optimal equipment selection is essential for efficient mining, we have developed an integrated toolkit for equipment selection and dimensioning to deliver the best possible system. Additionally, based on our expertise in plant engineering and mine planning, thyssenkrupp can optimize the dimensioning of equipment by tailoring the design of available equipment to specific mining conditions and customer needs.

To some extent, continuous systems follow different constraints than discontinuous systems. For this reason and depending on the overall mine design, a modified mine schedule has to be developed.

As all steps in the planning process of the various systems are dependent on each other, the overall planning process is iterative.

A techno-economic evaluation summarizes every study and relevant KPIs are evaluated. However, the system evaluation inevitably comes down to CAPEX and OPEX estimates by means of one of several discounted-cash-flow methods. Sensitivity analyses are carried out as costs are likely to be estimates and the sensitivity of the system to individual variables affects the accuracy of these estimates and hence the overall result.
