The objective of the mandate was to complete the engineering designs and study in support of mine production and material flow. The material handling system included 36 deliverables, which were provided to Opinaca Mines in accordance with the work packages. Our experts had to configure multiple bins with multi-dump points on the grizzlies and take into account the impact of geological structures on bin strength and stability.
Pre-feasibility study
- Perform trade-off studies on material handling options
- Prepare the underground mine design for the material handling system
- Perform hoisting system capacity calculations
Feasibility study
- Prepare the underground mine design for the material handling system, including a geotechnical assessment review
- Calculate fleet and equipment size
- Prepare engineering designs for mechanical, electrical and automation systems, as well as piping and structures
Our experts recommended an underground electric/battery truck system, designed to recharge batteries during transport of ore from the ore pass to the ore bin. The selected truck system would have a near neutral discharge/recharge cycle so trucks can be used throughout an entire shift.
Our specialists also recommended installing a tele-remote breaker operator system, controlled from surface, so autonomous haulage trucks could eventually be installed.
