Can00336: The speeds involving drills with productivity modules were wrong. Fix this and the outputs as a result.

{{Languages}}
Mining drills are used to automate the extraction of resources. Drills are the first step to automating manufacture, although most 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).

=== Mining By Hand ===
When mining by hand or with a tool such as the [[iron axe]], the formula is modified slightly:
(1 + Mining Speed Modifier) * .6 * (Tool power - Mining hardness) / Mining Time = Production rate (in resource/sec)

This uses a player mining speed of .01 per tick or .6 per second, and their bare hands with no axe uses a Tool power of 1. The Mining Speed Modifier is typically 0, but can be modified via mod or console command.

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 center 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.

Can00336: Fix vehicle speed bonus as it was wrong.

{{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 !! Vehicle acceleration bonus !! Vehicle speed bonus !! Train max speed
|-
| {{imagelink|Wood}} || 2 MJ || 4 MJ per raw wood || 100% || 0% || 259.2 km/h
|-
| {{imagelink|Raw wood}} || 4 MJ || 4 MJ per raw wood || 100% || 0% || 259.2 km/h
|-
| {{imagelink|Small electric pole}} || 4 MJ || 8 MJ per raw wood || 100% || 0% || 259.2 km/h
|-
| {{imagelink|Wooden chest}} || 4 MJ || 2 MJ per raw wood || 100% || 0% || 259.2 km/h
|-
| {{imagelink|Coal}} || 8 MJ || 8 MJ per coal || 100% || 0% || 259.2 km/h
|-
| {{imagelink|Solid fuel}} || 25 MJ || 2 MJ per unit of [[crude oil]]1 || 120% || 5% || 272.2 km/h
|-
| {{imagelink|Rocket fuel}} || 225 MJ || 1.8 MJ per unit of [[crude oil]]1 || 180% || 15% || 298.1 km/h
|-
| {{imagelink|Nuclear fuel}} || 1.21 GJ || 9.68 MJ per unit of [[crude oil]]1 1.21 GJ per [[Uranium-235]] || 250% || 15% || 298.1 km/h
|-
| {{imagelink|Uranium fuel cell}} || 8 GJ2 || 507 MJ per [[uranium ore]]3 || Unusable || Unusable || Unusable
|}

(1) 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]]. More efficient methods are possible. In practice, the [[petroleum gas]] is more likely to be used for something other than solid fuel.

(2) This fuel type can only be used in a [[nuclear reactor]]. Unlike other fuel types, it cannot be placed into standard burners.

(3) Assuming that all U-238 is enriched, all used up cells are reprocessed, and there is no reactor neighbor bonus.

== Consumption ==

The following formula can be used to find how long a fuel will last in a device:
<code>Burn time (s) = Fuel value (MJ) / Energy consumption (MW)</code>

For example, when using coal in a [[burner inserter]] with an energy consumption of 188 kW (or 0.188 MW): <code>Burn time = 8 / 0.188</code>

we find that the burn time is approximately 42.55 seconds.
