Underground resources are accessible only by the underground mining drill, and work like oil in that they lose richness (chance to produce) but eventually reach a minimum value. Underground mining also has a chance to bring up stone instead of the desired resource.
Adds the tech Combustion drilling (and Combustion drilling 2), which unlock the diesel mining drill and the underground (burner) mining drill, respectively. The diesel drill is simply an improved burner mining drill; the underground mining drill allows access to the new underground resources.
Underground resource generation can take a little time (especially if loading a large existing map, or loading for the first time after adding a mod that adds a new resource) on startup. When loading an old map, underground resources will be generated based on current surface values, not original ones. To force generation of underground resources based on original methods, use
Code: Select all
remote.call("underground-mining","regenerate")
Code: Select all
remote.call("underground-mining","regenerate","iron-ore")
Using this method will *not* work nicely with alternate resource generation mods such as RSO, but rather will produce underground resources based on what vanilla autoplace settings would have yielded.
Mod authors: read the notes in data.lua to change the default behavior of this mod with your resources.
- Fixed bug where the mod 'forgot' it had already generated ores, leading to sometimes enormous load times, every time.
- Version for Factorio 0.12.11+
