Miner is the skill associated with both the mining labor and its associated profession. Miners are necessary to build any kind of fortress that is underground or involves stone. They are required to dig tunnels, channels, stairs and ramps, as well as remove said stairs and ramps. Miners require a pick to do any work. The quality and material of the pick doesn't affect how quickly they mine.

Miners gain experience for every tile mined, which means they gain experience faster in easier-to-dig soil and slower in stone. Due to the constant demand, straightforward work and fast experience curve, miners level-up to legendary skill faster than any other profession. Most players will have one or two legendary miners within thirty minutes of gameplay.

Mining skill affects only the speed at which stone is mined, not the chance of acquiring resources from mining. Normal rocks and ore deposits drop an average of 1 boulder for every 4 squares mined; in compensation, one ore gives 4 bars of metal (although some types of ore sometimes give 1-4 extra bars of another metal) and one stone boulder yields 4 blocks. Gem clusters drop rough gems 100% of the time. Graphically, miners will often wear white tunics to resemble their occupation.

In order for any mining to be done, the designations menu must be used.

Mining behavior[edit]

Main article: Mining

If a large area is designated for mining, miners tend to clear out the left side first, working from the top down as much as possible. This is not absolute but is a strong tendency.

Once mining, a dwarf will automatically continue on to mine any connected tiles (on the same level) designated for mining, even diagonally, rather than shift to mine a discontinuous tile.

Dwarves tend not to see tiles on different levels as "connected" (e.g. an up-stair below a down-stair), and will tend to clear one level before moving on to another - even to the point of moving far across a map to do so. They seem to mine top levels over lower ones. If no mining-designated tile is connected, they will seek to mine a top-left-designated tile on a top-most level.

Mining speed[edit]

A zero-skill Miner takes 20 job ticks (5 per 'wear' on the wall being dug - a soil tile would just be 5) at about 11 frames per tick, for a total of about 215 frames to mine a single tile. A Proficient miner, however, did the same work in only 60% of the time (12 job ticks, 3 per wear level). A Legendary miner did the job in 20% of the time (4 job ticks, 1 per wear level).

If you're doing a lot of digging, starting with a semi-skilled Miner can save you a lot of time.


The miner skill is also used when fighting with a pickaxe. Pickaxes are brutally effective weapons, combining a piercing and a slashing attack, and make really good weapons for adventurers. Immigrants can come to the fort with low-quality copper or bronze pickaxes, so consider replacing them with better-quality materials, like iron made by skilled weaponsmiths. Despite their effectiveness, however, a miner who is attacked when they're busy mining will not generally use their pick in combat, unless they are forced to.
