Underground Mine Design, Planning and Engineering

We have years of first-hand underground mine engineering and operating experience in most countries and across multiple commodities using all common mining methods. As a global Geocardinal Engineering group, we have specialist underground mining expertise to provide solutions for the unique features of each project.

Based on this extensive experience, we utilize an innovative and rigorous mining method selection and planning methodology that maximizes 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.

Brainstorming sessions with our clients at the project scoping stage foster innovation in bringing out project development alternatives for analysis and ranking. 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 optimized plan is defined and accepted.

We recognize the constant need to match changing commodity prices and capital costs with appropriate responses from mining operations: reduction in operating and/or capital costs when prices fall, and increasing capacity when prices rise. We are focused on producing practical mine designs and achievable schedules that make the most effective use of mine capital, in both short and longer term time frames.

Whether optimizing an existing operation or deciding how to extract a new deposit, Geocardinal Engineering can help to ensure that appropriate solutions are understood and implemented.
