Bowman completed an environmental sound assessment to support permitting for a 34-acre life of mine expansion, including extended operating hours and modifications to mining methods.

Bowman completed an environmental sound assessment for a 58-acre life of mine expansion to evaluate existing conditions and understand how future operations could affect the surrounding area. The team conducted ambient noise monitoring to establish baseline sound levels, then analyzed expected equipment noise and developed models to predict operational impacts.

• Since 1992, Our team has assistance Pike Industries with surveying, site design, permitting, stormwater management, erosion control, construction, and ongoing permit compliance at their various Vermont facilities.

The client was looking for a safer and more efficient way to transfer ore to the main course ore bin. The existing ore dribble chute was scanned in 3D and used to design a new dribble chute and platform. The new dribble chute design changed the location of discharge from a conveyor directly to course […]

Crush/Convey department wanted to implement a new system to lift and convey belt feeder drive motors to a roof opening area. Project objective was to evaluate existing capacity of ceiling beams for trolley and hoist system designed to remove and install belt feeder motors to a roof opening area. Bowman provided a load rating and […]

The existing counterweight on the 7B conveyor had a winch system with inadequate lug connections and was rigged at an improper angle, which created structural integrity issues. Bowman calculated the take-up weight on lateral beams to size counterweight box and evaluated counterweight lifting methods compared to the existing winch system. Bowman prepared an economic trade-off […]

Bowman provided engineering services for a construction drawing package for access road grading and drainage improvements. The haul roads were severely damage during storm events so collection, conveyance channels, sediment traps and culverts were designed to manage a 25-year, 24-hour storm event. The design also included a paving plan for specific haul road sections to […]

Based on previous wash settler design experience, Bowman was uniquely qualified to do a feasibility study (FS) design for a new solvent extraction (SX) plant at a different operation for the Sierrita Mine. The project required a closely coordinated team of process, mechanical, civil, structural and electrical engineers. Bowman successfully integrated Plant 3D, Revit and […]

Bowman provided construction engineering services. Because of changes in the planned use of the AB-BC Tailings storage facility, the diameter of the slurry distribution pipes were reduced from 18” to 12”. This and other changes were implemented in the pump set ups. These changes resulted in overall improved decant system efficiency.

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