Hayward Baker working at an elevation of 12,000 feet in CO to plug a core hole with grout to a depth of 500 feet for water cutoff.

Installation of wick drains up to 180 feet in order to facilitate better drainage in a heap leach pad.

Oil Sands Tailings Pond required a mechanism for accelerating the dewatering of a mature fine tailings impoundment. Hayward Baker installed wick drains to dissipate excess pore water pressure.

At an Indiana Coal Mine, settlement of the conveyor tunnels and stacking towers was observed soon after they were constructed. Hayward Baker mobilized to perform an extensive fast-track compaction grouting program to re-level the tunnels and stacking towers.

When an abandoned 20th century coal mine was discovered beneath the cafeteria at a PA High School, Hayward Baker installed low mobility grout columns to reduce the span of the unsupported mine roof, alleviating concerns over future collapse.

An abandoned gold mine was discharging acidic leachate, and was leaking into a tributary of the Yellowstone River. Hayward Baker mucked out the adit to provide access for crews, equipment, and materials.

When this MSE wall supporting a crusher ramp at an AZ copper mine failed, Hayward Baker quickly stabilized the wall with an emergency ground anchor program.

A proposed cement plant had several challenges to overcome during construction. Hayward Baker was involved in construction of each of these facilities and used a variety of techniques to provide a cost-effective solution.

A cutoff wall constructed around an arctic lake was intended to prevent groundwater from entering an adjacent open pit mine. Windows were observed in the slurry wall, which would allow water infiltration, so Hayward Baker performed jet grouting in extreme weather conditions to seal the gaps.

Hayward Baker has completed numerous decant line abandonment projects throughout the US for a variety of mine owners.

A rock drill and a long-lead production drill are completing a coal mine remediation grouting program beneath a proposed Senior Living Facility.
