This mod adds some stacked recipes as well as a recipe modifier setting, allowing you to stack large volumes of mined items in an assembly machine, rather than multiple stacking beltboxes. Good for fast miners in late game with high mining productivity.
This is no longer being worked on - Take it and reuse if you wish. As an alternative, I would suggest https://mods.factorio.com/mod/Kythbloods_Stacked_Mining
