EVALUATION OF BOREHOLE MINING AT THE HANSEN

Borehole Mining in conjunction with Kinley, who are experts and pioneers in this method of mining. Simpson went on to say: “Borehole Mining could make a good fit with ablation technology and we will continue to evaluate this combination. Ablation could also be applied to any conventional mining method.

Borehole Mining - Kinley Exploration : Kinley Exploration

Borehole Mining. No longer a science project, borehole mining is proving itself as a workable technology that can be applied to a number of industries. Hydraulically jet-cutting a cavern of rock 20 feet in diameter from a drilled bore hole allows this system to recover resources previously uneconomical for open pit or underground mining operations.

Borehole - Wikipedia

A borehole is a narrow shaft bored in the ground, either vertically or horizontally. A borehole may be constructed for many different purposes, including the extraction of water, other liquids (such as petroleum) or gases (such as natural gas), as part of a geotechnical investigation, environmental site assessment, mineral exploration, temperature measurement, as a pilot hole for installing ...
