Mine Design and Planning

The company provides engineering, mine design, and mine planning for the following types of operations:

  • Surface quarrying operations – an evaluation of the reserves, structural geology and rock type is made from on-site visits and drilling information. Slope stability analysis is completed with haulage studies and a review of blasting practices.

  • The quarry plan is then designed to maximize recovery and minimize operating costs.

Underground operations – current underground mines are evaluated for efficiency of haulage, drilling/blasting, ventilation, dewatering systems and evaluation of current roof control plan and pillar designs.

  • Transition to underground – this includes the economic evaluation of reserves and the determination of the economic point of transition from a surface to an underground mining technique. The costs associated with this technique and the evaluation of potential success of the underground operation including infrastructure evaluations are completed

Trouble-shooting services are provided to evaluate the reason for slope failures and corrective measures are provided. Review of roof and pillar problems are completed with recommendations and provisions to eliminate the effects of “bad ground” in the future.
