Royalties company linked to NSW mine ends investment in thermal coal

A London-based resource royalties company with a stake in a north-west New South Wales thermal coal mine has announced it will no longer invest in thermal coal extraction.

The Anglo Pacific Group acquired Whitehaven Coal's Narrabri mine in 2015 but has since expanded its portfolio to include other facilities such as the Kestrel coal mine in Queensland's Bowen Basin, and the Four Mile uranium mine in South Australia.

In a statement, Anglo Pacific said the Narrabri mine represented just 7 per cent of its revenue in 2019, and this number is expected to decline further.

"This is part of a clear strategy to move towards lighter, greener materials, which encompass environmental benefits and many of which form part of the new wave of technologies around electrification," the statement said.

The announcement coincided with one of the world's largest banks, JPMorgan Chase, declaring it would stop lending to companies for whom coal mining is the primary revenue stream.

Right, I am the troll.  And I am the ONLY one who has been right about the situation on this thread since 2016.

No, you haven't. You've been saying all along that it is impossible, that it will never happen. You're wrong. It's happening.

Meanwhile arthwollipot is bragging about driverless cars in mines.  Wow.  They have had driverless trains in London since 1967.  They also have had boats with autopilot since the 1920s and the first autopilot for planes was in 1912. 

So, any day now I guess...

"Bragging"? No, I'm correcting your lack of knowledge about the real world. And you didn't even read the article I linked to. I can tell, because I just realised that I'd messed up the link when I posted it. Busted, you.

The link is fixed now and should work.

FYI, they're not driverless cars in mines, they're 360-tonne hauling trucks. And autonomous navigation of a vehicle is a lot more complicated than either a train, which is constrained to travel only on a clear track, or autopilot for boats and planes, which only ensures that the craft is travelling in a straight line.

Do you guys make stock picks too?

What's that got to do with anything?

I fully acknowledge that there is technology capable of being tested.  You can take a truck, and let go of the wheel and it will drive relatively straight. 

I am not sure where you go with it from there, because a truck that can control itself 90% of the time, is still probably not all that useful to a delivery company.

As has been shown, there are fully autonomous trucks doing complex tasks in mines.

The vehicle and its occupants sat quietly and waited at an ideal vantage point. They were parked at a lookout, with sweeping views of the red and yellow Pilbara earth. Coming into view was a technological leap that proponents argue will change mining forever.

It was impossible to miss: A fully-loaded haulage truck the size of a double-storey house on wheels, travelling at an estimated 60 kilometres an hour. But what was unique about this truck was it didn't have a driver.

Mining industry veteran Gavin Yeates, who was in the group of observers, says the autonomous truck, which weighed about 390 tonnes, was travelling along smoothly when something unexpected happened.

"It was one truck going at a good clip and a flock of birds, white cockatoos or something, flew across in front of it. And the truck instantly saw the birds and put the anchors on," he recalls.

"The sensors and things on the front of that truck picked up the birds and it was reacting," he says.

The incident happened at a mine about five years ago, during a driverless truck trial. In the time since, the number of autonomous trucks in the Western Australian iron ore mining industry has soared to reach about 240, and it's still climbing.


So what does autonomous mean in a mining operation, and how does an autonomous truck move around?

There isn't a human in the cabin, or a person controlling the truck every second remotely with a joystick.

Instead, the truck is loaded with ore by a human loader operator, who then gives the truck its destination. The truck knows where to go because of information about routes that are programmed by staff in a far-away operations centre.

The truck, which has a range of sensors that help it navigate, then drives itself to its destination. According to observers, the vehicles - which can travel at speeds of up to about 60 kilometres per hour - are very good at keeping their distance from one another, never forming a compressed conga line while en-route to their destination, which could be many kilometres away.

The trucks have enough "smarts" on board, according to Yeates, to detect objects like other pieces of machinery in their path, and steer around them. They know to slow down when travelling around a corner, change down gears when going uphill, and to keep their distance from the truck in front.

Then, when the truck unloads at its destination, staff in the operations centre direct it precisely where to unload.

Yea, they are testing them.  They have been testing them for a long time.  They are at level 2 at best.  Not even close to be autonomous.  They aren't going to be unmanned anytime soon.  Like I said, its not too hard making a self-driving car run around a race track.

I don't know about you, but I'd prefer they spend plenty of time testing. Wouldn't want to rush something like this.

In how many years will there be big rig trucks with no driver in them at all, or where the driver is allowed to sleep during the drive?

You're asking us to predict the future again, phooey. None of us know how long it will take. Putting a number on it, we now know, will merely allow you to gloat condescendingly again when we get it wrong. I can't speak for anyone else, but I have no interest in that.

So the largest tobacco supplier in India is not "Big Tobacco" in your mind?

That's convenient.

Fun fact: The largest tobacco supplier in India is ITC Limited, which reports an annual turnover of US$8.31 billion.

It seems most likely that the self-driving tech will probably start out being used in commercial vehicles, and then eventually spread to private cars later.

I've long been of the opinion that one of the first markets that autonomous vehicles will spread into, and the first set of workers to be dispossessed of their jobs because of it, is long-haul trucking.

Incidentally, Skeptics with a K did a full show review of Goop Lab recently. Worth a listen. The most disturbing part to me was that the show completely ignored best practice for talking about suicide. That could cause real harm. I have a friend who is a suicide survivor, and I did my due diligence and gave her a content warning just in case she was thinking of watching it out of curiosity.

Like I said, I enjoyed it. And it's not like they do a schtick like this very often.

Just walked into the bathroom where I interrupted a conversation being held between a guy sitting in the stall and a guy standing outside of the stall.  That is not ok!

The only acceptable reason, the guy taking a shit was the only person who knew what wire would cause the bomb to explode and which one would stop the timer.

It also looks like you're using the Whey theme, which has a fixed-width text space. Images that are larger than that width get scroll bars. Yes, it's annoying, but I consider the fixed-width to more than offset the inconvenience. After all, I can always right-click the picture and open it in a new tab.

This is so horribly tragic on so many levels... A tragedy because a healthy person died doing something stupid. A tragedy because nobody stopped him.

And emblematically... a tragedy for our civilization. In the age of vast technology and space research... a person died trying to prove that the Earth was flat.

People die doing extreme sports. I see this as the same thing. Yes, a terrible tragedy, but no more or less so than someone dying in a base jumping accident.

I think many people acknowledge that a screw-up in 3D (airplane) is likely to be far worth than in 2D (car), so safer, sure but a small failure is worse.

But, driving on roads, with intersections and bicycles and pedestrians and the other guy and weather and terrain and traffic is far more complex than flying.

The consequences of a mid-air collision may be more severe than the consequences of a surface collision. Risk formula: chance of something going wrong multiplied by consequences of something going wrong.

The extent to which Americans love displaying their flag is frankly weird to us foreigners.

I understand.

The concept of having a Queen and even placing her on money is frankly weird to us foreigners.   >:D

Not to mention having that same monarch in charge of your church (which I am guessing is not the case where you live)

Who needs a flag when you have got a Queen or King to display.

Well you also have the fact that you literally fought a war to kick the monarchy out of your affairs. We never did that. The country was founded, and still is populated in the majority, by people who descended from the English. The Queen is more or less omnipresent. When I was in scouts I pledged allegiance "to God and to the Queen". I guess the same goes for your flag.
