I read that to get diamonds you should mine a whole chunk. what's this "mining a whole chunk" mean?

I would also like to ask that would I get diamond for sure?

What Kenjara said about chunk size is correct. However I would add the following points.

  • Diamond Ore only appears below level 16
  • The highest concentration of diamonds occurs between levels 5-12 but because of lava lakes there is slightly less in the middle of that (~9)
  • There is ~1 diamond ore vein generated per chunk.
  • An ore vein will have between 3 - 8 diamond ore in it.
  • However, that vein can be overwritten by other generated structures - such structures, such as caves, can leave you with a chunk with no ore vein in it.
  • Because of this, it is possible to mine an entire chunk and still not get any diamonds.

Because of these points and how long it would take to mine an entire's chunk worth of diamond possible blocks there are more efficient methods than mining every block in the range. If you want to be absolutely certain you don't miss it the most efficient method is lane mining. This is the method where you expose the maximum amount of blocks for inspection while mining the minimum amount.

So pretend this is a top down view of a layer of stone

You would want to mine like this

So you leave two lanes of unmined stone between each mined lane. This lets you see the contents of both of the unmined lanes by walking down the mined out lanes, and reduces the amount of total mining by to a third of what mining a whole chunk would take.

  • Cool. I will try that. – Fennekin Oct 21 '14 at 15:49

    Lane mining, at least as described above, isn't the most efficient method. The above allows for 2 blocks seen per block mined but it's possible to get nearly 4 blocks seen per block mined. – Annan Oct 21 '14 at 19:45
  • @Annan The best you can get in practice is 6 seen per 2 mined, because you need to be able to walk. You can achieve this through a honeycomb pattern. By spacing out the honeycomb pattern further 1 block, you can still get almost the same returns by asserting that a vein will never be in the uninspected blocks without also being in an inspected block. – Riking Oct 22 '14 at 0:09
  • @Riking - Also see gaming.stackexchange.com/questions/8310/… – Bobson Oct 22 '14 at 18:10
  • @Riking Ah! Yeah, was thinking about Dwarf Fortress mining. 6 per 2 sounds right. – Annan Oct 23 '14 at 19:49

A single chunk is A 16 X 16 area 256 blocks deep. It is probably saying to mine a 16 x 16 area at the level diamonds appear.

As far as I am aware this will not certainly get you diamonds. You are probably better off looking for dirt at the levels diamond exist and mining all of the dirt as diamonds can appear among it.

For diamond mining tactics check out the wiki. http://minecraft.gamepedia.com/Tutorials/Diamonds

  • So i have to mine 256 blocks? Starting from height 16 – Fennekin Oct 21 '14 at 11:46
  • No because diamond only appears between levels 2-16. You need to dig at those levels. – kenjara Oct 21 '14 at 11:49

    It will get you diamonds. There are a fixed number of diamond veins per chunk (3 if I recall correctly), so unless you're unbelievably unlucky and they all get cut off by caves, you will find them. – Quentin Oct 21 '14 at 12:02

    why the dirt tip though? just because it is faster to mine? – Fungo Oct 21 '14 at 14:15
  • @Fungo it's way faster to get a shovel instamining dirt than a pickaxe instamining stone. – Quentin Oct 21 '14 at 15:54
