Hydraulic Borehole Mining

Hydraulic Borehole Hole Mining (“HBHM”) is sometimes referred to as Borehole Mining (“BHM”), Jet Mining, Jet Boring, Underground Hydraulic Mining, In-Situ Mining, Jet Underreaming, Water Jet Borehole Mining or Water Jet Mining.  In all cases it refers to using high-pressure water or fluid to disaggregate, mobilize or erode subsurface resources and concurrently using Kinley’s airlift or venturi/eductor pumps to lift the disaggregated material back to surface.

There is a large push both domestically and internationally for sustainable and economic mining methods that offer better economics, safe and environmental access to resources with near zero surface disturbance, lower capital investment and decreased carbon costs - an advantage to all stakeholders. HBHM serves as both the drive for stronger ESG fundamentals and for driving costs downward on previously uneconomic and inaccessible extractives.

Depending on the resource to be recovered, HBHM provides an economic advantage by having the ability to access the resources otherwise not economically viable with traditional mining methods. HBHM technology provides for a shorter time to first production, the ability to target high grade zones and be selective based on market conditions on what is mined. HBHM, for instance, can access targets outside of a primary open pit area, or underground working or areas that are in environmentally surface sensitive, yet still utilize existing processing facilities. The HBHM mining footprint is short term and much smaller than conventional methods while the resource can be accessed vertically, horizontally, or directionally depending on site and overburden conditions.

With HBHM and associated reduction of the work force, decreased moving of mobile equipment on site, and the elimination of open or underground workings offers a significant risk reduction and enhanced control of health and safety.

HBHM equipment can be operated remotely and in isolation of people, ground water and dilutive substances. Targeted resources can be isolated from the resource face right to extraction without exposure thus limiting risks as used commercially in the mining of high-grade Uranium.

Given the equipment size and power requirements HBHM leads to a reduced total energy and surface disturbance footprint, reduces associated emissions, and improves energy sustainability. The water used in HBHM is recycled leading to reduced water usage and the tailings can be used used as a backfill agent to decommission mined out resource bodies.
