Explore Mining and Operational Design Solutions

For more information regarding our Mining services, please contact Jason Andrews, P.E. 

Engineering Analytics, Inc. (EA) has extensive expertise providing engineering solutions for mine and mill sites. EA’s senior staff have on average over 25 years of experience serving the mining industry. Together they have extensive expertise providing environmental and engineering solutions for mine and mill site permitting, operations, closure and reclamation. EA has successfully completed projects for numerous mineral, metal, uranium, aggregate, and coal mine and mill sites across the United States and around the world.

EA’s technical services include geologic engineering support for mining operations, such as: geotechnical evaluations, hydrologic characterization, water management, including collaboration with treatment specialists, as well as optimizing the water treatment process and management of treatment residuals. We complete engineering design for open pits, tailings impoundments, waste rock piles, heap-leach piles, and other mine features. EA routinely provides engineering design, plans and specifications, construction management, and construction oversight services. Our staff have designed and executed sampling plans for mine materials, air, soil, sediment, surface water (including lakes and reservoirs), and groundwater as part of permitting and closure of sites.

Areas of Expertise:

Reclamation and Closure

EA provides complete reclamation and closure plans addressing heap leach pad, tailings impoundment, and waste rock closure. Our services include site grading, erosion and groundwater control, acid rock drainage mitigation, slope stability, cover and liner designs, geochemistry, and water balance. In collaboration with our clients, EA develops the best strategy to manage the environmental risks associated with closure and reclamation of mine sites.

Water Treatment, Electrical Design, Controls and Instrumentation

EA staff has expertise in all phases of design, repair, upgrades, and optimization of industrial and mine water treatment technologies and systems. EA offers expertise in water treatment optimization, process and pipeline design, electrical system and instrumentation and controls design, storage options, including tank and impoundments, sampling and monitoring, and bench and pilot testing for industrial and mine waters.

When should we bring Engineering Analytics into a mining project?
During early feasibility or before permit submission. Early involvement aligns technical assumptions with regulatory expectations and reduces redesign and schedule disruption later.
Can Engineering Analytics support active operations and long-term closure strategy at the same time?
Yes, and this is common. Integrating operational design with closure planning improves cost forecasting, reduces future retrofit requirements, and keeps regulators satisfied throughout the project lifecycle.
What information does Engineering Analytics need from us to get started?
Site geology, production plans, monitoring data, and known regulatory constraints. Prior technical reports and environmental history are also important.
How does coordination with our internal engineering or environmental team typically work?
Coordination is structured around defined scopes, shared data, and scheduled reviews. Engineering Analytics works from client operational inputs and regulatory goals to keep design and permitting on track. Clear communication prevents costly delays.
How are design changes handled during active mining?
Through formal revisions, recalculations, and updated drawings, with regulatory notifications prepared when required.
Will Engineering Analytics represent us in meetings with state or federal regulators?
Yes. Their team participates directly in technical discussions, responds to agency comments, and prepares the documentation needed to move approvals forward.
How early does closure planning begin?
Typically during early design phases. Regulators often expect a closure strategy upfront, and early planning reduces bonding uncertainty and long-term liability exposure.
Does Engineering Analytics provide construction oversight for tailings, heap leach, or waste rock facilities?
Yes. Field construction is verified against design specifications and quality control documentation is maintained to reduce long-term performance risk.
How are project cost estimates developed?
Estimates are based on site data, engineered quantities, and long-term monitoring assumptions, prepared at conceptual through detailed levels depending on project stage.
What differentiates Engineering Analytics from a general civil firm?
They integrate geologic, hydrologic, and geochemical data directly into mine design rather than treating them as separate studies. That integration, combined with deep permitting and closure experience, allows designs to anticipate regulatory requirements before they become problems.
