Strategic Underground Mine Planning and Design
The underground design team at Qubeka brings years of practical mine operating experience together with the latest in mine software. This ensures operational issues and concepts are considered from the earliest stage of a project to ensure project success. Various mining methods are considered in conjunction with the client to arrive at a design that meets or exceeds their expectations. Based on this extensive experience, we utilise an innovative and rigorous mining method selection and planning methodology that maximises the economic benefit of the project. The methodology focuses on understanding the complete mining context or characteristics of the deposit. This understanding is fundamental to selecting the appropriate mining method and establishing a robust mine plan.
Preferred solutions are identified through detailed mine engineering and trade-off studies. 3D underground design, optimized production scheduling and mine cost modeling are used to assess project economics, beginning at an early stage in the planning process. All mine design and schedule opportunities are left open until an optimised plan is defined and accepted. Whether optimising an existing operation or deciding how to extract a greenfield deposit, Qubeka can assist to ensure that appropriate solutions are understood and implemented.
