On-demand modern air
Closed quarters and with no breeze, sustaining modern air for workers is a crucial and dear part of any underground mine.
At Greens Creek, Hecla is using the wi-fi underground connectivity for on-demand air circulation, an optimization-via-automation methodology that targets the vital strategy of supplying modern air to underground miners of their scattered workplaces whereas exhausting the used air that has acquired further heat, noxious gases, and dirt.
By mounting variable-frequency drives to the underground followers that circulation into modern air by the underground workings at Greens Creek, the air circulation system is able to modify the amount of up to date air delivered in response to the people and instruments in an area.
The company says merely one among these drives lowers the annual power bill at Greens Creek by about $23,000. So, the mine could save spherical $1.26 million per yr when all 55 of the followers are equipped with these drives.
In the midst of the testing part, Hecla put within the money-saving variable drives on 14 of the followers.
“We’re already saving money instantly, and will roll out this know-how all by Greens Creek and our totally different mines to doubtlessly save way more eventually,” Hecla penned on the enhancements net web page of its web page.
Distant vein miner
As a forward attempting agency, Hecla has its eyes on the way in which ahead for underground mining. This consists of being the first agency to order Atlas Copco’s distant vein miner, a state-of-the-art mining machine that features the a lot of steps of underground mining proper into a gradual operation.
With a cutterhead that digs into the face being mined, the distant miner does away with the drilling and blasting traditionally used to interrupt up ore.
This revolutionary mining machine is being put to utilize at Lucky Friday, an Idaho silver mine merely 4 miles from the place Hecla acquired its start in 1891.
Since its start in 1942, Lucky Friday has produced better than 155 million oz of silver, along with healthful parts of lead and zinc. Hecla first bought into Lucky Friday Silver-Lead Mines Agency, operator of the underground mine, in 1958. Six years later the two corporations merged, bringing Lucky Friday into the Hecla portfolio.
Hecla is taking Lucky Friday to new depths with the No. 4 shaft, which may develop mineralization 10,000 ft beneath the ground and add better than 20 years of silver-rich ore to the operation.
The distant vein miner is predicted to alter into increasingly more very important as Hecla follows the rich silver ore deeper into the Lucky Creek Mine.
“We see mechanical rock lowering as an very important step forward to significantly improve productiveness and safety as we mine at higher depths on the Lucky Friday, and are proud to be working with Atlas Copco, a frontrunner inside the space, to develop the distant vein miner,” acknowledged Hecla Mining President and CEO Phillips Baker, Jr.
It is this work on the lowering fringe of underground mining know-how that is anticipated to take care of the 130-year-old Hecla going strong by the twenty first century and previous.
