BTW you don't need that much coal. you can split the coal/ore on one belt.
something like this. coal on the near side of the belt works best.

I had problems with this idea because the splitter only split half the material. The design you posted is awesome! Get 2 splitters ...

Yes I know! hehe

How can I solve this, I Have 20 electric miners, do I need even more? How many miners feed 24 Furnaces?

Right now I am considering not using a Splitter for the 2 lanes of ore. Instead I could get a separate Iron ore mining facility and feed each line with its own mine.

Hello,

Ive been playing Factorio for a few days now and I'm having a blast!

One recurring issue I have with my Factories is that my Iron Ore supply is not enough to feed my Furnaces. Any advice would be great!
