You could randomize the field that resources are taken from, so that this happens evenly.

So there must be a method in the mine that does it already. You can pull it out and make it available for the AI to use. Something like void percentage_of_coal_available(field, radius, coal_resource_index, & total_pieces_of_coal_at_start, &total_pieces_of_coal_now);
