The mining of resources is generally done with a pickaxe, but can be done with anything. Mining drains Stamina and causes your tools to lose durability. The lower your Stamina and tool durability, the slower you will be able to break blocks.
In this picture, the player chances upon four ores (from left to right): Lead, Potassium Nitrate, Iron and Coal.
Basic Mining Information
Since the 8.7 update, mining has become much easier - it is much more common to find different kinds of ore veins than before. However, miners tend to be confused by the ore texture bug, which is not yet fixed.
- The following mineral will make a stone sound when being mined: Coal.
- The following minerals will make a metallic sound when being mined: Lead, Potassium Nitrate, Iron and Tungsten.
- Ores tend to be generated in the map as ore veins - deposits of the same ore that are placed right next to each other. As of Alpha 8.7, it is very common for veins to intercept each other, allowing a single vein to potentially lead into many others.
- The most common tools for mining are Stone Axes (for early mining), Pickaxes (for mid game mining), Augers (for late game mining), TNT for clearing mines and a weapon to detonate the TNT.
- To use TNT, seal it in a hole and use a firearm (not a crossbow) or a Pipe Bomb to detonate it safely. The trick to get maximum effectiveness for a TNT is to have it as covered as possible. The blast radius isn't that big - players can stand 5 blocks away without getting damaged.
- As of Alpha 8.7, ore deposits can generate right below grass/sand/snow level.
Mining a tunnel is more or less safe, however there are some things to keep in mind.
• Be careful if you are thinking of mining big rooms, as mining too big without supports will cause your mine to collapse on your head and possibly kill you. To counter-act this make sure you leave support pillars.
• Sometimes when mining, the block you just mined will sink into the blocks around it making it hard to pick it up. Walk right on top of them and hold E.
• Lighting is very important while mining. There is no minimum spawn radius, so if you are underground and its dark, there is a chance that a zombie can spawn and attack you before you are ready. So place lots of torches to ensure there is not a sneak attack. Torches also help you visually distinguish ores from stone.
• Some biomes have a layer of what looks like concrete, however, when it is broken it will only drop Destroyed Stone. One biome is the Wasteland biome.
• A bunker is a good safe house, however it can be difficult to get food and water.
• It's a good idea to have two exits, a main one and a secondary one. This second one can be used if your normal exit is blocked off.
• If your mine is directly accessed from your house, be sure to build a secure Door to prevent other players from accessing your house, should they manage to dig into your mine.
• As of Alpha 9.0 there are 3 minerals per layer. There is stone and iron ore in every layer. The third mineral changes every twenty layers down starting with coal, then potassium nitrate, then lead, and finally tungsten.
