[[Mining drill]]s are used to automate the extraction of [[items#resources|resources]]. Drills are the first step to automate manufaction, although most [[items#resources|resources]] have to be smelted in a [[furnace]] for further usage.

== Mining Speed Formula ==

Metal and mineral resources have a "mining hardness" rating. The rate at which they are produced is given by:

(Mining power - Mining hardness) * Mining speed / Mining time = Production rate (in resource/sec)

To calculate the time needed for one resource-item use this formula:

Mining time / ((Mining power - Mining hardness) * Mining speed) = Seconds for one resource item

Mining power and speed are functions of the miner while hardness and time are functions of the metal or mineral you are currently mining (you can place a miner over a mixed field).

Note, that the Burner mining drill covers exactly its size (2x2, and so covered area is also just 2x2), while the Electric mining drill is one tile bigger (size is 3x3, but covered area is 5x5). Place Electric mining drills in the centre of resource-fields as narrow as possible, but at the borders of the field, more loosely to get a more continuous throughput by having more equal resources per miner.

Unlike most other equipment, mining drills will output resources directly without the need of [[inserter]]s. This includes [[Transport belts]], [[Chests]], other mining drills (makes only sense for [[Burner mining drill]]), [[Furnace]]s, [[Assembling machine]]s etc.

Burner mining drill

Mines about 7 resources per single unit of coal used to fuel it. Covers and mines in a 2x2 area. Mines 0.28/s of copper, coal or iron and .3675/s of stone. Burner miners create a lot of pollution per resource.

==Self-Sustaining Coal Mines==
Both methods use no electricity to work.
=== Method 1 ===
Two burner mining drills can refuel each other, when placed next to each other on a coal deposit as long as they're facing each other. Each drill fuels the other and coal gradually accumulates in their [[Storage/Stack]]s, so you have effectively a storage of 100 coal (2 stack, 50 coal, one in each burner miner, together 100). You can do this also for 4 or any other even number of miners, though [[Electric Mining Drill]]s are far more efficient once [[Electricity]] is available. You can also use chests and burner inserters to increase coal storage. Images: [https://postimg.org/image/j0m27t3j5/] (without chests) and [https://postimg.org/image/dcvvyci69/](with chests).

=== Method 2 ===
This method can be used for any number of burner mining drills in a coal deposit. Place a burner mining drill, then place at least three [[Transport belt]]s from the output in a mirrored "L" like shape so that the third belt has a gap between it and the miner. Fill the gap with a [[Burner inserter]] in a way that the inserter can insert coal to the miner. Image: [https://postimg.org/image/of10ko49j/]

Fuel

2016-07-15T10:57:19Z

Nicholas Robert: /* Types */ Some grammatical changes

{{Languages}}
[[Fuel]] can be inserted into [[burner devices]] and burned to power them. Different types of Fuel provide different amounts of energy, measured in megajoules (MJ).

== Types ==
This is a list of all [[Items]] usable as [[Fuel]] in burner devices, ordered by fuel value:
{| class="wikitable"
! Item !! Fuel value !! Fuel value per raw total
|-
| {{imagelink|wood|Wood}} || 2 MJ || 4 MJ per raw wood
|-
| {{imagelink|raw-wood|Raw wood}} || 4 MJ || 4 MJ per raw wood
|-
| {{imagelink|wooden-chest|Wooden chest}} || 6 MJ || 3 MJ per raw wood
|-
| {{imagelink|coal|Coal}} || 8 MJ || 8 MJ per coal
|-
| {{imagelink|solid-fuel|Solid fuel}} || 25 MJ || 20 MJ per unit of [[Crude oil]] *
|-
| {{imagelink|small-electric-pole|Small electric pole}} || 4MJ || 4MJ per raw wood
|}

(*) This assumes the Crude oil is processed completely into Solid fuel, using [[Advanced oil processing]] and [[Heavy oil cracking]] as intermediate steps, but not [[Light oil cracking]]. Less efficient methods are possible. In practice, the [[Petroleum Gas]] part of processed crude oil is more likely to be used for something other than Solid fuel.

Note that through version 0.12.35, [[Rocket fuel]] is not Fuel and cannot be used in burner devices.
