The Grand Daddy Of Michigan Copper Mines -- Over 9000 Feet DEEP!

Link To Empire Mine:    • They ONLY Got 20% Of The Gold   #michigancopper #quincymine #coppermining The Quincy mine located in northern Michigan was one of the deepest copper mines in the world at the time and ran for close to a century. The depth was over 9000 feet deep. The life span of a mine depends totally on ore reserves along with the grade of the ore and also the ease of mining the ore. Most mines will have a life span of around 20 - 25 years. Some mines in the past only lasted a few years while others like the Empire Mine and the Sullivan Mine and the Quincy Mine, lasted a century. The Quincy Mine located in Hancock Michigan, came about due to what you could call a blunder in government operations. There was two different companies that had recorded claims in the same area and the government ended up issuing both companies the rights to the claims. Because there was what looked to be a promising ore deposit both the companies decide to merge and make the mine. In 1846 the merger between the Northwest Mining Company and the Portage Mining Company was done and the Quincy Mining Company was formed. The Quincy Mine was a mine that had some very unique engineering designs. It's number 2 shaft was the deepest shaft in the world at its time. It reached a depth of 9260 feet and went off at an angle of 55 degrees. The number 7 shaft is unique in that is was driven on a catenary curve. It also had the worlds largest steam powered plant. This plant was needed for the hoist to be able to reach great depths to be able to bring up ore and workers. It weighed more than 880 tons, and could lift 10 tons of ore up the shaft at a speed of 36 miles per hour. This alone saved over $16,000 in fuel bills in its first year of operation. The hoist sat on the largest concrete slab ever poured at that time. The slab alone contained almost 3200 cu. yards of cement and over had over 8 tons of reinforcements. Thank you for watching!
