The Big Hole: Moving underground.
Going underground brought new challenges.
Such as developing supporting technologies to prevent collapses and rockfalls
Devising signals and standard methods of communicating.
Bellow is a chart of various sequences of knocks or rings for if the regular bell system was out of action.
Then of course there is always that ever present requirement to answering natures calls, even when underground.
Apparently it's not just loading rocks that cocopans are good for...
... and the birds still use it today, their "aim" is just not that accurate ;)
they can't seem to reach the hole and hit the lid.
To think all this effort was made for about 3 of these cocopans
22.5 million tones of rock was excavated to recover 2.7 tones of diamonds
That's a ratio of 64 carats per 100 tonnes
Therefor on average 1 cocopan/ton would yield less than a carat of diamonds. Its easy to see how many miners got despondent and made nothing for their efforts. It requires moving massive amounts of kimberlite to retrieve enough diamonds to make it profitable.
In short...
If you don't have loads of capital, to throw at automation when mining diamonds, its likely to end up being a fools errand... kind of like bitcoin mining these days.

Thanks.
This is great - so interesting. I never wondered how miners answered the call of nature underground - guess I thought they buried it :) Thanks.
I hadn't thought about it much either, till I saw this
:-) not the kind of information you seek out every day....
I've actually been down in a couple of mines, just never needed to answer the call I guess....
You should write that this is part of a serie at the begining if not in the title. I went through all of that trying to search for a context.
Look like it's about a diamond mine...
You may find it more effective use of your steem power to vote for things you do like instead of downvoting things you don't...
By upvoting posts you like it will automatically bring the payouts down on high trending posts that you don't like by redirecting some of the rewards.
This is a far less "in you face" method of encouraging and rewarding, with your steem power, more of what you like.
Downvoting also hurts your steempower investment growth long-term as there are no curation rewards allocated to downvotes.
If you really feel you need to downvote to make a statement, use a lower percentage as that will not consume as much of your voting power and you will have more votes to spend upvoting good posts.
Thanks for reminding me, It's just simpler for me to upvote and downvote everything I check based of the accumulated reward vs how I value such content (taking into consideration the age of the posts)
I think having a curated frontpage can increase the value of my steem more than what I can get from the curation rewards.
Personally, I don't mind flags, but most users of this platform do... especially one as big as yours.
Your flag by itself however can't remove significant rewards or anyone from the front page, once they are there... so you are not really achieving a curated front page.
Having a curated front page is one thing, but having an upset user base is another, flagging is far more likely to create the latter.
A 15-20$ difference by itself may not take someone off the front page but most of the time will move the post a rank or two higher or lower.
If you edit your post to address the confusion that might likely turn at least one downvote into an upvote.
It's not my downvote I'm worried about, as stated I don't mind them... Its the others on the trending page, on users that battle to get there and haven't see many rewards for their efforts.
What you are talking about is also inversely happening all the way down, rewarding anyone who didn't made it to the frontpage.
Fair enough... just din't be surprised when you start getting hate posts about your flags.
They seem to draw attention more than nice rewarding upvote... go figure.
