Boart Longyear Drilling Service's Exclusive LR90H


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.

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 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.

Boart Longyear Drilling Services operates the exclusive LR™90H 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.
