== Method ==
Mining is primarily done in caves. Activate a [[Pickaxe]] and right-click a rocktile, then select Mining -> Mine. Every Not all mining actions done on a rocktile give rockshards, however every mining action on done inside a regular rock tile cave gives a rock shardrockshard. +/- 25 60 mining actions creates a cave entrance. Within a cave, +/- 50 mining actions are required to continue the tunnel.

To find specific ores, you should [[Prospecting | prospect]] on the surface. Prospecting in the cave itself will only tell you the quality of the tile (assuming you have at least 20 prospecting skill).
== Reinforcing cave walls ==
You can reinforce cave walls by adding a [[Support Beam]] to it. You cannot mine a reinforced tile, but it will prevent cave collapse. To prevent a tile from collapsing, you must reinforce all of it's walls. Veins count as reinforced walls.
== Multiple tunnels ==
Remember that the Wurm world is a 2D world and that all tiles are pillars. You can mine up and down but you <b>can't</b> make a tunnel above or below another tunnel. It is possible but it will make a big hole between the tunnels.
