Love watching them try to load the massive boulder on the 777 in the background at 7:30 only to see it on the ground at 9:00 where they wisely dumped it! Great video!
If I tried to load that rock here I'd be standing in front of the boss explaining myself. If it don't fit in the bucket it gets shoved aside. But different places different techniques. But the one around the 10 minute mark I'd load. It's in the bucket nothing says three quarters can't be sticking out
Excellent video PA 👍👍👍 Like a trip down memory lane. This was the core of Scottish opencasts during my time as a sunshine miner... 250-300 tonne excavators matched to 777's, 33-11's, 33-100's and the like.
@@PAmining yeah it Evoques fond memories. The TR-100's were making inroads but the last 2 mines i worked were all CAT dumpers so i never got a drive in a TR-100. Scottish coal bought quite a few so they couldn't have been bad...
Woulda been a good 30min vid watchin em move them pebbles…got a pic of a 385b puttin 1 ona 773 pipelinin around a miller bros. job back in 09..hydros let go once tryin to get it up luckily it was when the truck pulled up..still on my old black razor phone
Most of the time it's personal preference. For example , this site has run backhoes since 1982 and that's what they are used to. The electric vs diesel is more of a site specific requirement
@rmorganii I’m only going to reply to the second part of your question. Normally electric cable shovels are working at long term mining operations.The mine might be active for 10 years or more.The cost to purchase a large electric shovel is extremely high. New units in the 90-110 ton capacity range can cost the mine owner 20 million US dollars.Large hydraulic shovels are substantially cheaper.The large diesel powered hydraulic shovel is also more flexible on the mine site.This is because it isn’t tethered to a power supply cord. The day to day operating costs are definitely lower with an electric powered shovel.However, keep in mind that the infrastructure to supply electric power throughout the mine site is not a simple or inexpensive process.As you can see there are many factors to consider. Basically, if you are going to be digging hard rock overburden over a period of 12 - 20 years, then you would opt for the large electric powered rope shovel.I believe the best manufacturers of rope shovels pretty much guarantee at least a 20 year operating life for their machines.One example of the type of machine I’m referring to is the P&H 4100XPC.The 4100 is legendary in the mining industry for its performance,reliability, and ruggedness.I’d estimate a new unit in 2024 to cost 20 million USD or more.
Once the overburden is gone, how is the coal handled? I've seen what seem like endless videos on many channels of overburden being removed, but I can't recall ever once seeing coal be handled.
Usually smaller excavators remove the coal seams because they can clean it better, however if the seam is really thick, it's not uncommon to see a machine the size of the 3000 bailing coal. Also! There are many coal loading videos on my channel, have a look! Thanks
