TypeMultiblock machine

The Void Ore Miner is a multiblock structure added by Environmental Tech. It can create various ores and crystals using energy (FE). It comes in 6 tiers.


When supplied with enough FE, the Void Ore Miner will periodically generate ores of various types, which will be automatically output to inventories adjacent to the Controller. This process can be sped up by placing Speed Modifiers in the appropriate slots in the structure. Specific ores can be made more likely to appear by using a colored Laser Lens, and this effect can be amplified by using Accuracy Modifiers.

The Void Ore Miner also requires its Laser Lens to have a straight view to either Bedrock or The Void in order to work. Transparent blocks such as Glass, walls, or fences may be used to provide a safe path under the structure without blocking the beam.

The stats of each tier of Void Ore Miner are given in the following table. "Minimum time per ore" is the minimum time per ore that this tier of Void Ore Miner can reach using Speed Modifiers, "Modifiers to reach max speed" is the amount of Speed Modifiers needed to reach it and "FE per ore (max speed)" and "FE/t (max speed)" are the respective values when this amount of Speed Modifiers is used. Note that adding more Speed Modifiers than this value will increase the FE per ore (and thus FE/t) without increasing the speed, thus wasting power.

Every time the Void Ore Miner produces an ore, it is randomly pulled from a table depending on its tier. These tables can be freely configured, including their contents and the weight of each entry (entries with higher weight will be picked more often). By default, this includes a variety of ores (such as Iron, Copper or Draconium), Lonsdaleite Crystals (which gain a higher weight as the tier goes up) and all other Environmental Tech crystals depending on the tier (such as Kyronite or Ionite).

If the appropriate colored Laser Lens is used, the item will have a bonus to its weight, according to the following formula:


  • bonusWeight is the bonus weight given to each appropriate entry
  • totalWeight is the sum of the weight of all entries (before the bonus is applied)
  • nbEntries is the total number of entries
  • accuracy is the amount of Accuracy Modifiers in the structure
