I'm trying to harvest the maximum amount of uranium possible from a small patch. Unfortunately, there is a bordering coal patch nearby as well, and two of my electric mining drills are within range of this coal, and as such, mine some of it:
I put a chest in front of each of their outputs with a filter inserter to take only the uranium out. But when I first fired up these drills, they mined coal, which is now sitting in their chests. After a while, they switched to uranium. Is it possible to control what ore it harvests? I want it to focus only on uranium.
