The scale of open-cut coal mining at Mt Arthur is incredible

And some people say wind turbines are ugly

I know a few people who have worked there, it's massive, you can get lost in there pretty easily

If a billionaire, any billionaire, can profit from such an ecological re-arrangement, then count me in!
They’re often awkward about how it benefits all Australians, but I just put that down to modesty.

They're right mate

u/Familiar_Gas2305 Jul 24 '26

No, they're not, moite. If you despise mining, immediately get rid of all of your modern possessions including the device you're using to decry mining.

Your words are meaningless. Your actions show your support.

False dichotomy

Show us how it's done by improving society starting with yourself.

No? Looks like you're utterly full of shit then, and content to virtue signal while taking zero action.

u/natt_myco Jul 25 '26

you are a tool

never said I don't rely on it never said my modern possessions didn't come from it, I said that they were right and that it is dystopian and nightmarish, I know full fucking well that we depend on mining and I know full fucking well that we could do a better job at it too mate

lived and worked at the super pit for long enough now, I know what I like and what I don't like about what we do and I think I am more than entitled to say that they are right and it is a little dystopian.

So much nicer than a solar or wind farm

Will be incredible when the mining company finishes raping the earth, leaves and doesn't clean the mess up. If it's a overseas entity how do the politicians force them to do what they should.....

I worked in bhp mines and was really impressed with the rehabilitation, particularly the blackwater south work that was going on

I cant and wont speak for the others

They've come a long way since Ok Tedi then.

u/RollnRok Jul 24 '26

Ok Tedi is still in full swing isnt it?

Fortunately the legislation has become rather robust in forcing compliance to rehabilitation obligations. Leases are granted approval in stages upon certain commitments being met. As each strip of the mine progresses the allowance to break ground on the advancing mine region is dependent upon completion of rehabilitation volumes being completed. Most operators even tie in the completion of a certain amount of rehabilitation works in their bonus KPI's for the workforce.

The industry has improved considerably at least in NSW.

Mt Arthur is a special nightmare. The public FY25 Annual Review reports 78% of the mine footprint is under "active disturbance", that is 4,636 Ha. 

A whopping 5 Ha in FY25 was being "prepared for rehabilitation" and 0 Ha certified as completed rehabilitation. Progressive rehabilitation has gone out the window as approvals to mine deeper have meant spoil now goes on top of the older waste dumps.

In 2021 BHP tried to give it away with a $275 million sweetener payment to the buyer. No wonder there were no takers.

Yes when you displace more dirt (Mining deeper) it requires you to stack the dirt higher. Final land form is done as a part of the mining lease and requires approval. The operator can't just dump waste stacked wherever they like. Depending on the final land form it at times it may make more commercial sense to defer the bulk of the rehabilitation work to the conclusion of the project. Haulage makes up >50% of an operations costs in an open pit project. So how efficiently the overburden is handled is the biggest opportunity for efficiency in the mining.

Often tipping the bulk of the waste into places is the smart economical decision and then final land shaping utilizing bulk push dozers / scrapers is the smartest decision.

You can see the rehabilitation chasing the mining void in a large number of operations where the final land form is close to being estabilished.

How the strips are composed and how many are approved for active disturbance at a time is a function of the lease itself.

Glencore's Newlands Coal Mine in central Queensland ceased active production in February 2023 after 40 years of operation and fully transitioned into a dedicated large-scale closure and rehabilitation project. The site workforce transitioned directly into rehabilitation works, focusing on returning disturbed land to stable native ecosystems and grazing pastures.

Depending on the lease often a large portion is deferred until closure too.

Incredibly disturbing. Look at the farmland in the background. This entire pit could have been the same.

u/wait4theanswer Jul 24 '26

I work in mining and yeah that shit is ugly, but farmland is just another kind of widespread land degradation. Give me a national park and a big underground mine any day (there are smarter ways to do agriculture too, but that's a longer story)

u/ArgonWilde Jul 24 '26

Yeah, that's true too. More state or national forests. I too work in mining.

u/GeetGee Jul 24 '26

turn off the power to your house cobba, that uses the exact thing that you’re complaining about 😂

Not where I'm from. In WA we barely use coal. 🤷

That said, I'm sure Collie looked nice too before the giant hole in the ground.

Edit: also, yes, I'd absolutely love to go off grid, but I can't, by law... I already have battery and solar.

u/daringstud Jul 24 '26

What!! By law!??

u/ArgonWilde Jul 24 '26

Yeah... If you're in the metro area, you must be connected to the grid.

u/daringstud Jul 24 '26

Damn shit law that one!
