Native Plant Species for the Reclamation of Uplands
A functional assessment of upland native plants in the Hudson Bay Lowland was conducted to determine their potential to disperse, establish, grow, allocate resources and contribute to the ecosystem development. Sixteen simple traits (plant height, leaf thickness, stem density, ability to fix nitrogen, etc) were measured on three populations of 67 species near the Victor…

Application of a Polygeneration Optimization Technique for a Hospital in Northern Ontario
Polygeneration systems are integrated energy supply systems that simultaneously generate two or more energy carriers (e.g. electricity and heat); where the output or byproduct of one process can be the input for another energy supply process). Hospitals are considered good candidates for polygeneration systems due to their sustained and relatively high energy requirements…

Hydraulic Air Compressor for Cooling Deep Mines
Using the energy from water flow in a natural watercourse to produce compressed air is not new; 100 years ago such installations were termed hydraulic air compressors. Today, if natural hydropower resource can be harnessed, compressed air from this technology could be produced at close to zero marginal cost. Such a benefit forces reappraisal of processes and methods that…

Sankey Trees: Visualization of energy flows
Reduced energy consumption for mining operations is a desirable goal, however understanding the opportunities for optimizing energy consumption is not always clear. The Sankey diagram, which has been used for over 100 years to visualize the flow of energy, materials, or cost through various processes provides an option, but there are drawbacks to this approach: i) the…

Upland Reference Conditions
Uplands without water-logged soils are rare in the vicinity of the Victor Mine. The question arises as to what the reference conditions or targets for restoration should be when reclaiming new upland deposits of mining wastes, roads and gravel pads. This is of particular importance when aiming to rehabilitate new upland features to sustainable ecosystems dominated by native…

Rehabilitation of Peatlands after Mining
Over the course of a 3 year study, control plots without Sphagnum fragments did poorly but all those that received fragments had a >70% bryophyte cover and 30-60% Sphagnum cover, even without a mulch or companion plants. The spreading of fragments is therefore needed but no mulch or companion plants are required to restore these peatlands. The study shows progress towards…

Evolution of the Sudbury igneous complex contact metamorphic aureole and controls on anatexis
Field observations indicate that large portions of the South Range metamorphic aureole surrounding the SIC can be resolved despite complications due to post-metamorphic events, primary lithologic heterogeneities, and the geometry of the SIC contact. Geochemical data has proven useful in establishing fingerprints to distinguish rocks that are highly affected by contact…
