For anyone that enjoys Minecraft, this is a mining pattern I use to maximize resource yield and minimize digging. Although this diagram is specifically targeted at diamond mining, the pattern works equally well at any depth for other resources.
One of the reasons this pattern works well is that most resource veins are at least 2 blocks wide so most veins will be exposed. I recommend mining out any coal, redstone or lapis that you encounter, even if you don't need them as they produce XP and may lead to exposing diamond that may otherwise have been missed.
I usually cut a long corridor (3x3) at level 11 around 80 or 100 blocks long. I set up a centrally located work area with trunks, furnaces and water. Always carry a bucket of water for hardening lava or putting yourself out after you've fallen into lava.
Cut into the walls with 3 high by 1 wide branches about 20 blocks deep, putting torches every 5 blocks in. I ignore exposed resources for now. When you reach 20 blocks cut across left and right 4 blocks so when you cut the branches on either side of this one, you will know when you reached 20.
Now back track out the way you came and mine any exposed resources as you go. When you reach your main corridor, store your new valuables in a trunk and cut another branch 3 blocks over from the one you just made.
When your whole corridor has been branched, go down to level 5 and repeat but make sure your branches line up exactly between the ones above as indicated in the diagram.
To truly maximize your efforts, read up on enchanting and make sure you only mine your diamonds with a "Fortune" pickaxe which increases the yield on an ore block. It can be tricky getting this particular enchantment so try to at least get a "Silk Touch" pickaxe which will harvest the ore intact allowing you to store it away until you get "Fortune". #minecraft #diamond
