The Big Hole: Becoming Mechanised
Removing and processing the weathered kimberlite or "yellow ground" had been relatively simple to do by hand using picks, shovels etc.
Once hitting "blue ground" or unweathered kimberlite individual mining became more difficult, slower and less profitable due to encountering harder and harder rock.
Wealthy miners began buying up the claims from despondent individual and small operations around them and one or two large consolidated mining companies began to emerge.
With all the "rats and mice" miners out of the way mechanization could begin in earnest.
Dynamite was used on the hard rock and shaft were sunk next to the pipe to begin mining the pipe from the side and below.
Large headgear hoist were set up to hoist broken rock from below.
The rocks were loaded by hand into cocopans (small iron wagons that run on rails) seen below painted green.
Each cocopan holds about a ton of broken rock.
The vertical down shaft was sunk a safe distance from the main hole but close enough to limit the railing and transport required underground.
Some of the other mine buildings and other paraphernalia have been restored and preserved as part of the exhibit.
From this angle you can get a good view of the suspension apparatus installed for viewing the big hole.
Old steam rock crushers and other steam driven equipment is also on display.

Hi buddy. like old photos? Come visit my blog.
Don't worry @gavvet...
This is the last spam link about abuse that I will post on a SG post. Don't get me wrong, I still believe you all are scamming the system to the detriment of all other Steemiams. I'm just bored with you all and with viewing any content on the trending (SG) page.
So go ahead and finish your series. I'm sure everyone is eagerly anticipating "The Big Hole" Volume 347.
Please spread the word in your SG chat.
You have some truly sick cartoons about people offing their own children. I hope that you get help. If you don't like the content on Steemit, then the community will thank you for moving your troll activity elsewhere.
I am offended @steemship.
They were EATING OTHER PEOPLE'S CHILDREN.
Can we please get our facts straight!?
Okay. You have convinced me. I will seek help for my sociopathic tendencies. Can you recommend a psychologist that accepts Steem?
The community? Or you and the SG?
Thanks for the comment @steemship
Nope. I think I'm gonna eat some kids tonight. Maybe my own?? 🤔
