TL;DR
Electric Mining Drills which would only mine ores of one type.What ?
One problem I have is overlapping ore types ... like coal and copper, iron and stone. The output contains both ore types which then must be separated. It is bothersome to place mining drills carefully or to set up filter inserters to "clean" the output, as this slows throughput down.I suggest adding an item called a Filter Miner. This would look exactly like the current mining drills, but would have the ability to mine only one type of ore. Perhaps it could have an interface similar to a filter inserter.
Example: You place one on a bed of ore containing copper and stone. You click it to open the interface and select copper. The Filter Miner then only mines the copper and ignore the stone.
As for crafting, I would suggest a recipe of a filter inserter or maybe a stack filter inserter and a regular mining drill. Maybe some extra green and/or red circuits too
Why ?
I believe this would improve the game by reducing of the inconvenience associated with mining.Thank you for reading!
