Noticing all the cities with big holes coming in the streets, some from old mining activities, some from broken pipes,
my question is where does the dirt go,
I have to spread mine all over the ground, and am not allowed to remove it from the claim
any answers out there

From the most recent blow out in Sydney it looks like a lot of the dirt is blasted up, and then washed away with the torrent of water. The huge hole in the Sydney blow out yesterday took out 2 cars, trees, power poles and lines, and exposed gas pipe and other essential services. The gas pipe exploded apparently. The water took the soil away down the hill. I've seen one of those blow outs in front of a used car yard. The mud was all over the cars and the gravel yard, and then down the street to the river running through Adelaide, ie. the Torrens River. I was the car detailer. All my shiny cars were covered in mud, gravel, stones and whatever else was blown out of that hole. Not impressed getting to work that morning! The hole wasn't very big, maybe the size of 2 cars to the kerb. It also happened recently in Ipswich, right in the centre of a major city intersection. These pipes aren't immortal. They are aging, rusting or corroding. Something has to go sometime. What will happen in a few years above the tunnels they're drilling to create roads and railways. Perth has the railway tunnel, and Brissy now has a tunnel for future traffic managment. The price of progress. Who know what future generations will have to do to maintain or repair this infrastructure.

Sydney's water and sewer infrastructure has been so neglected for many years that it's a wonder that any pipes still carry water of sewage. They were told that a relining of the old pipes was possible but chose to run their luck and now it's all become a reactive situation of repair as necessary. What was 5 billion is now going to cost 10's of billions

Typical government decision - any level of government. I bet they haven't been saving up for the big job. It's happening everywhere. Everything old is now older.

I guess the simplest way to get rid of the dirt you've dug up, would be to just dig a hole and bury it!

Good one mate, that will keep me in giggles for a while

The size of the hole will depend on the amount of dirt we have to bury.
