Havnt been on in awhile, just wanted to give everybody a cool mining fact. I do mine for a career but it is for coal, the yellow stuff is much prettier!! Ive operated our dragline for a couple of years but have worked on it for 18. It is a bucyrus erie 1300. Boom is 325ft long and dump height is around 200ft. The bucket is 35yd., 12ft wide & 18ft deep. This sucker weighs around 4-4.5 million pounds.( the space shuttle is similar in weight!) The drag ropes are 25/8" (2 of them) and have 500,000 ft/lb. torque & and they can break!! It is powered by a 7200 volt extention cord. Digging cycle time is good under 1 minute. Could you imagine how much gold you could uncover with this machine. And you know how they say to drill(sample). Coal mining is the same here. We know where to go, if it starts to dive or climb.
Anyways,
thanx for checking out

Cool. Thats a big piece of machinery for sure. Theres a large dragline at Ester near Fairbanks that they used for stripping overburden in front of the dredge. That thing is cool to go inside and imagine running it. Quite a machine.

It is truly a monster:

One of their customers is Suneel. The Ak RR delivers the coal to the loading facility in Seward. The gondolas of coal are so heavy that it takes six diesel-electric engines in tandem to pull it. A cargo ship comes in once or twice a month to take on a load of coal that then is taken to South Korea. I believe they use it for electricity generation.

Do they use coal in the larger Alaska power plants? It's funny but I never thought of coal in Alaska.

They supply coal to six interior power plants.

I needed one of those on East Beach. :)
