== 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:
 
  (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:
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 time / 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).

When mining by hand or with a tool such as the [[iron axe]], the formula is modified slightly:  
When mining by hand, the formula is modified slightly:  
  (1 + Mining Speed Modifier) * .6 * (Tool power - Mining hardness) / Mining Time = Production rate (in resource/sec)
  (1 + Mining Speed Modifier) * .5 / Mining time = Production rate (in resource/sec)
 
[[File:player_mining_bar.gif|thumb|468px|none|Progress bar when the player mines by hand.]]
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.

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), and the Big mining drill is two tiles bigger than the electric mining drill (size is 5x5, and area covered is 13x13).

Mining drills can only be placed on resources.
