MINE DEWATERING CAPABILITIES
Large open pit mine operations encounter groundwater as mining progressively expands and deepens. As a result, groundwater inflow can cause significant disruption to a mine and impact production and economic performance. Consequently, the cumulative costs of wet mining, while hard to directly measure and quantify, can be in the tens of millions of dollars annually. Hydrogeology design to remove or move water saves money and increases production.

The benefit of consulting with and selecting Boart Longyear is that we do it the right way the first time for the best outcome possible. Our experienced and highly trained crews get it done faster and better and save money for the mine over time.

LARGE DIAMETER WELLS
Boart Longyear is uniquely qualified to drill and install large diameter wells to pump water out of the pit and make it available for other mine operations. This type of drilling can be highly technical with fractures, varying ground conditions, and lower water tables.

HIGH-WALL STABILIZATION
High-wall stabilization is critical to continuous mine operations. Boart Longyear Drilling Services can help. Consult Boart Longyear whether you need horizontal drilling for a self-draining hole into a water table, or your project requires high-wall stabilization where there’s too much water for horizontal drains.

MOST ADVANCED DRILLS AND EQUIPMENT
Boart Longyear Drilling Services operates the exclusive LR90H Horizontal Drilling Rig for mine dewatering. This FOPS Level II certified rig drills a hole at a 5-degree angle for self-draining dewatering – directly against a high-wall face for the best productivity. This electric rig offers completely hands-free rod handling and can drill 152 to 182 m (500-600 ft) in a shift.

The LR500 is capable of drilling holes up to 152 cm (60 in) down 1524 m (5,000 ft) with a finished hole of 35 to 40 cm (14 to 16 in). The LR500 is the only rig in the market to accomplish this diameter and depth. With 226,796 k (500,000 lbs) of pullback and auto-drilling features, this completely electric rig automatically adjusts the weight on bit, torque, feed, and mud for the straightest holes.

Boart Longyear specializes in both above and below ground dewatering pump systems and provides a variety of installations, maintenance, and removal of dewatering pumps for service or replacement. Our specially designed and tested methods reduce groundwater levels and head pressures in pit walls and underground.

GEOTHERMAL WELLS
Boart Longyear provides experienced crews in geothermal well systems. We provide geothermal well installations includ­ing drilling, set up, casing installation, and blowout preventer equipment installation. Additional services include the remov­al of geothermal wells systems for replacement or repair. Boart Longyear has performed work in places such as Fallon, Nevada; Lightning Dock, New Mexico; Raft River, Idaho; and Neal Hot Springs, Oregon. Let us help you with your next geothermal well installation or repair/replacement project.

DIVERSE FLEET OF PUMP HOIST RIGS
Our large, dedicated pump hoist rigs are specifically designed to lift heavy casing and pumps out of the ground, and up to 250,000 pounds. These rigs are used in pump rehabilitation where large well pumps need to be serviced or replaced.
