− | + | '''Mining''' is an essential part of building a fort in Dwarf Fortress. There are several reasons you might want to mine, such as gathering various [[stone types]], or simply to create the basic tunnels and [[rooms]] in your fort. Only dwarves assigned to "Mining" will actually mine the areas you want to have mined, and then only if they have access to a [[pick]] and can physically reach the site. | |

− | + | All the [[stone]] types produced by mining must be hauled away or they will soon clog up your tunnels. Loose stone will not impede movement, but it can prop open doors, slow construction, and prevent open space from being used as a [[stockpile]]. You can assign stone hauling duties to specific dwarwes just like you assigned them to be a miner. Make sure you have stockpiles where all the different [[stone]] types can be stored, too. Be careful which dwarves you assign to hauling if you have a massive dig going, or they might drop whatever other important stuff they were doing just to clear the paths. Typically miners will mine out stone far faster than haulers can properly clear it, particularly if the stockpile is a distance away. | |
− | + | There are alternatives to hauling. [[Mason]]s or [[Stone crafter]]s can build their respective workshops next to or on top of a large pile of stone for clearing, and then create items out of the stone to clear it. Masons can create [[furniture]] (which takes as much space as the original stone itself, but is at least useful); they can also create [[block]]s, which unlike stone and furniture can be stacked in [[bin]]s. Craftdwarves can create various smaller items which can also be stacked in bins. Assuming you have sufficient bins, place a stockpile right next to the worksite and your haulers will only have to take the items a very short distance to place them neatly in stacks. This is a huge timesaver on large projects. Just be careful about what you make. Stone blocks are useful, but a bin completely full of stone blocks is extremely heavy and hard to move around. Crafts of all sorts are usually very light, but certain job types make multiple products out of single stones, which will multiply your hauling problem. Stone crafts, as opposed to, for instance, mugs, will produce single, lightweight, somewhat valuable items that are easy to stack and move. | |
− | + | Not hauling at all is also possible. You don't have to clear the rubble. However, if you are a typical DF player, you desperately want to. | |

− | + | '''Digging''' is a group of actions available from the [[:category:designations|{{K|d}}esignations menu]]. Digging is performed by dwarven [[miner]]s in order to create empty spaces, hollow out material or dig stairs and ramps. All dig actions require a dwarf with the miner skill and an available [[pick]]. | |
− | + | === Digging in 3D === | |
− | + | The map is divided in ''layers''. Tiles on each layer are composed by whatever is on that tile, and the floor (or absence <BR>of floor) below it. A virgin rock tile is composed of a wall of rock and a floor of rock, for example. The ''ceiling'' of a tile is the same thing as the floor of the layer above that tile. | |
− | |||
− | |||
− | + | The most basic dig action is {{K|d}} '''mine'''. When this option is selected you can mark areas to be hollowed out from the current layer. Any useful material such as rock or ore is deposited on the ground excavated by the tile. Digging a tile preserves both the floor and the ceiling of that tile. | |
− | + | [[Image:DF_Terraform.PNG|thumb|664px|Graphical representation of several situations. This is a cross-section. "Sky" is dug-out, even underground, green is floor, non-sky cyan is no-floor, and "rock" is rock.]] | |
− | ]] | ||
− | + | A similar action to dig is {{K|h}} '''channel'''. With this option it is possible to either select floor tiles (already dug out with {{k|d}}ig) or 'full' tiles. When dug out, the floor (as well as a wall if it exists) on your layer will be removed and the tile on the layer below will be dug out. Creating a channel could be described as 'strip mining'. | |
− | + | Because it has the potential of removing two layers of wall and one of floor, channeling has the potential to be the fastest mining method. However, be careful that multiple miners working on the same channel don't undermine each other, causing them to fall through to the tile below. If this happens you may need to build a stair or a ramp in order for the fallen miner to escape. | |

+ | |||
+ | === Stairs & Ramps === | ||
+ | |||
+ | For dwarves to move upwards and downwards between levels the construction of [[stairway]]s and [[ramp]]s is required. The most reliable way to assist your constructions is to dig an [[upward stairway]] on the lower level and [[downward stairway]] above. '''[[Stairs]] down''' only remove the floor, and '''Upward stairways''' do not affect the floor or the ceiling. '''Up/Down stairways''' act as a combination of both. | ||
+ | |||
+ | You can also construct these out of rocks or wood, but well placed dig commands are quicker. Digging downwards from the surface, first dig a {{K|j}} '''downward stairway'''. If you wait for this to be dug you will then see a visible block on the layer below where the stairway connects. In this tile dig an {{K|u}}'''pward stairway'''. Your dwarves will now be able to access both levels using these stairs. It is advisable to build one of these before channeling in order for your dwarves to escape. | ||
+ | |||
+ | It may be convenient to build an {{K|i}} '''up/down stairway'''. This automatically creates a downward stairway on the floor above if you have not done so.{{Verify}} This style creates an X symbol in place of a < on the default tileset, but leaves a > symbol on the floor above. You can also make a long series of up/down stairways directly above/below each other to make a long staircase that encompasses many levels. | ||
+ | |||
+ | Upward [[Ramp]]s remove the ceiling above them and create a down-ramp automatically. They can't be used by dwarves unless built specifically. Up-ramps can be found in the same submenu of the {{K|d}}esignation menu as up- and down-staircases. | ||
+ | |||
+ | Ramps should be avoided until you need to provide access to caravans as dwarves on the upper level cannot perform actions such as dig, or build when standing on the ramp ''(imagine they are 'half way' up the ramp)''. | ||
+ | |||
+ | Stairs and Ramps can be removed using the {{K|z}} '''remove up stairs/ramps''' command, ''if those ramps were originally built by digging''. Select this and mark the stairs/ramps to be dug out. | ||

Generally, they seem to pick the deepest, northwestern-most vein{{verify}}. Notably, dwarves <i>do not</i> pick the closest vein. |
Dwarves have a priority over which side they will mine out from. Unless there is something in the way, miners will try to walk around unmined areas to reach these preferred sides, even if that path is very long. In order from most preferred to least preferred, dwarves prefer to stand on the tile to the: <blockquote>West > East > North > South > NW > SW > NE > SE</blockquote> of the tile being dug. | Dwarves have a priority over which side they will mine out from.

Try to think of the mountain as a series of boxes where with a thin lid ontop of each. At any place the box can be filled or empty, and the lid above be there or not there. For example, you can create a wall and build a floor ontop of it. (Building a wall creates a floor on the next level by default, but this doesn't stop you building another floor construction ontop of it!) |
