Mining

There are already concepts that would see electric vehicles draw power from cables in the road, thus freeing those vehicles up from lugging around heavy batteries. British firm Texchange, however, is going a step farther – it's developing a system where the motor is in the "road," too. Read More
When winter arrives in much of the world, cyclists such as BMXers and freestyle mountain bikers are limited to riding in warehouse-style indoor bike parks. These places can be fun, but they're still ... you know, in a building. Such is not the case, however, with the just-opened Mega Underground Bike Park. Claimed to be the largest indoor bike park in the world, it's situated 10 stories (100 ft/30.5 m) underground in a disused limestone mining cavern. Read More
According to the World Gold Council, about 195,300 tons of gold have been dug out of the ground in all of human history. Countless lives have been lost obtaining the rare metal, and in the developing world, which currently accounts for 20 percent of the world's gold production, small-scale mining and smelting under primitive conditions poses a major health hazard. To help alleviate this, a team from Argonne National Laboratory and the US Environmental Protection Agency are developing a prototype mercury capture system to reduce heavy metal pollution. Read More
The depths of a coal mine couldn't be considered ideal driving conditions for most vehicles, but the Mk7.0 TIER 3 Mine Cruiser isn't most vehicles. GE recently announced that it has delivered its 500th Mine Cruiser, which is a four-wheel drive utility vehicle capable of carrying up to 14 passengers, yet is built to operate safely in the vast galleries of modern underground coal mines.

Scientists from Australia's Commonwealth Scientific and Industrial Research Organisation have discovered that eucalyptus trees in the Australian outback are drawing up gold particles from deep underground through their root system and depositing the precious metal in their leaves and branches. Rather than being a new source of "gold leaf," the discovery could provide a cheaper, more environmentally friendly way to uncover valuable gold ore deposits. Read More
Every year, Australian mining companies discard hundred of millions of dollars worth of gold. They're not doing it on purpose, it’s just that the standard industry technique of scanning mineral samples isn’t sensitive enough to detect small traces of the precious metal. Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) and Canadian company Mevex have tested a new technique using powerful X-rays that can detect these small trace amounts quickly and accurately.

“I’m Chris Lewicki, and I’m an asteroid miner!” These were the opening words spoken by the President and Chief Engineer of Planetary Resources Inc., as the asteroid mining company emerged from three years of silent running to outline its plans to mine Near-Earth Asteroids (NEAs) within the decade.

Planetary Resources, a new player in the commercial space industry, is backed by a host of tech and aerospace luminaries with an integrated personal net worth on the far side of US$30 billion. A press release from the company hints that it will look to establish asteroid mining operations in space. Read More

Plans are afoot to have humans back on the moon by 2020, but if we want to make it more than just a brief visit and truly begin to colonize the solar system, the challenge will be to find ways to extract and exploit local resources that can help sustain a lunar outpost. That's where the Scarab comes in. The four-wheel, 880-pound lunar prospecting robot designed by Carnegie Mellon University's Robotics Institute, and soon to be field tested by NASA on the slopes of a dormant volcano in Hawaii, is equipped to drill and collect three-foot samples of soil and rock while operating in one of the harshest environments imaginable - the moon's southern pole. The rover will act as a terrestrial testbed for the development of technologies that it's hoped can be used to find hydrogen, oxygen and possibly even water, that could be mined from beneath the moon's surface.
