The New Bronze Age: We’re Entering the Era of Tough Ore via BB.

Worries about oil and gas hog the airwaves. But copper is also essential to keep the world running: It threads through your house, your computer, your eco-correct hybrid car. And it’s getting just as difficult, expensive, and environmentally menacing as oil to extract. We have entered the era of tough ore.

  1. This is a cool machine! It’s a Sandvik DS310 Bolter; it keeps the drifts from caving in. Made in Lyon, France. It drills a 32mm hole 2m deep, into the ribs and back (minespeak for walls and ceiling; originally from working in the belly of the beast). Then it injects fast acting epoxy resin into the hole, jams a in rock bolt & torques it. Cycle time is about 90seconds, including the time required for the epoxy to firm up. Depending on ground conditions each bolt can have a pull out capacity of 50 tons.
    It’s a scary feeling when they start popping out!
