== Mining Speed Formula ==
Mining speed / Mining time = Production rate (in resource/sec)


Metal and mineral resources have a "mining hardness" rating. The rate at which they are produced is given by:
To calculate the time needed for one resource-item use this formula:


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


To calculate the time needed for one resource-item use this formula:
Mining speed is a function of the miner while mining time is a function of the metal or mineral you are currently mining (you can place a miner over a mixed field).

When mining by hand, the formula is modified slightly:

Expanded description:
  (1 + Force Modifier) * (1 + Character Modifier) * (Character mining speed) / Mining time = Rate


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


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).
The output of the unmodified resource is the percentage yield of the tile currently used by the miner.


=== Mining By Hand ===
  Output of unmodified field * ( Number of modules in miner * Bonus from module ) + Output of unmodified field * ( Number of beacons * ( Number of modules * Distribution efficiency ) * Bonus from module + Productivity research bonus + 1 ) = Raw output per second
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.
    (Raw output per second * Mining speed) / Mining time = Production rate (in resource/sec)

The mining drill or pumpjack will sum the production rate of all tiles below it and show that value in the tooltip.

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.

Mining is used to extract resources from the world. Mining drills are the first step to automating manufacture, although most resources have to be smelted in a furnace for further usage.

Mining speed formula

The rate at which resources are produced is given by: 

Mining speed / Mining time = Production rate (in resource/sec)

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

Mining time / Mining speed = Seconds for one resource item

Mining speed is a function of the miner while mining time is a function 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, the formula is modified slightly: 

(1 + Mining Speed Modifier) * .5 / Mining time = Production rate (in resource/sec)
Progress bar when the player mines by hand.

Expanded description: 

 (1 + Force Modifier) * (1 + Character Modifier) * (Character mining speed) / Mining time = Rate

Infinite resources

The output of the unmodified resource is the percentage yield of the tile currently used by the miner. 

  Output of unmodified field * ( Number of modules in miner * Bonus from module ) + Output of unmodified field * ( Number of beacons * ( Number of modules * Distribution efficiency ) * Bonus from module + Productivity research bonus + 1 ) = Raw output per second 

   (Raw output per second * Mining speed) / Mining time = Production rate (in resource/sec)

The mining drill or pumpjack will sum the production rate of all tiles below it and show that value in the tooltip.

Note, that the Burner mining drill covers exactly its size (2×2, the covered area is also 2×2), while the Electric mining drill is one tile bigger (size is 3×3, but covered area is 5×5).

Mining drills can only be placed on resources.
