Mining & Exploration

Mining is an industry that relies on a variety of engineering disciplines. From mining, geologic, civil, geotechnical, mechanical, chemical and environmental engineering, our in-house capabilities and deep bench of resources allows Bowman to provide total site and infrastructure solutions, from initial site exploration through reclamation.

In every aspect of a mining project’s lifecycle, Bowman is committed to delivering “fit for purpose” solutions with a sense of urgency and a strong commitment to client service and quality. Our clients additionally benefit from our ability to navigate the regulatory process and meet tight schedules, while maintaining a culture high in regard for health and safety standards throughout all phases of project execution. By consistently delivering high-quality, innovative, cost-effective and efficient management of mine site and design challenges, Bowman delivers successful projects time and again.

Project Highlights

Confidential Haul Road Culverts

Southeast, AZ
As a result of a new pit being developed at the mine, a haul road was developed from the pit to the existing crushing facility. Bowman designed six (6) culverts that allow stormwater to flow under the new haul road.

Confidential Leach Pad Phase II

Southeast, AZ
Bowman performed value engineering and design optimization for the phase II design of a leach pad in a canyon with aggressive slopes (~2.5H:1V). The design included liner subgrade, geomembrane and GCL, solution collecting pipe network, and overliner drain rock.

Confidential Wash Settlers

Southeast, AZ
Bowman, having previously designed the original settlers during another project, designed two new Wash Settlers with related structures, containment, equipment, storage, piping and instrumentation.

Confidential Stormwater Diversions and Culverts

Southeast, AZ
Bowman designed three stormwater diversions to protect a leach pad. These diversions required the engineering design of several structures including channels, levees, energy dissipation structures and box culverts. In conjunction with these designs, Bowman developed method specifications for compaction and a design for soil cement that utilized the material sourced from the channel excavation.

Confidential Stockpile Dams

Southeast, AZ
Bowman performed the engineering design and construction quality assurance for multiple stormwater retention dams. The design process included watershed analyses, lithological investigation and interpretation, earthen structure stability analyses, and flow considerations for a 100-year storm event.

U.S. Silica Inventory Verification

LA, MD, MT, NM, ND, OH, OK, PA, TX, WV
Our team was hired by U.S. Silica, a nationwide sand and aggregate company, to conduct volume analysis on stockpiles as a third-party inventory verification. We have performed volume analysis scans every quarter since 2014 in various states, including Texas, New Mexico, Oklahoma, Louisiana, Pennsylvania, Ohio, West Virginia, Maryland, North Dakota, and Montana.

Mined Land Reclamation Articulated Concrete Blocks

AZ
Confidential client in SE Arizona commissioned Bowman to conduct construction quality assurance (CQA) for articulated concrete blocks (ACB’s) installed in reclaimed mine areas for spillway down chutes. Verified installation of subgrade, geotextile, filter layer, geogrid, mats, concrete grout lines and anchor trenches to meet manufacturer’s specifications.

Harleville Hydrogeologic Investigation

Harleville, SC
Bowman geologists/hydrogeologists were responsible for the implementation of a groundwater investigation relative to a proposed quarry deepening.

Western New York Hydrogeologic Investigation

New York
Bowman completed a drainage basin analysis and groundwater study to evaluate the impact mining would have on the regional watershed within the Adirondack Mountains.
