ON TOP OF WHAT'S BELOW

摘要

Today, cesium ores are routinely shipped to Russia for the generation of electricity employing electrically conducting fluids (magnetohydrodynamics). Getting to the ore required sinking a single shaft and two ventilation raises into the pegmatite 60m below Bernic Lake. Actual mining is carried out using the room and pillar method, and interestingly enough, says Deveau, actually benefits from the mine's hard rock foundation. "This technique is best utilized in flat lying ore bodies in an environment where you don't have a lot of stresses from the surrounding rock," he explains.
