I know and I completely agree, however I don't plan to make any major changes to this mod. I have an upcoming reimplementation of this mod, which includes cave generation and has a much easier, landfill-like way to mine cave walls. These mods currently lack testing and graphics though. (I'm usually busy with university, and when I'm not I don't feel motivated to do these "tedious" tasks, so there has been a year with barely any progress)
The AAI miner mines ores if I'm not mistaken, so that will never work I'm afraid.
