Triple Coal Mine

Overview
The Triple Coal Mine is a Premium Tier item that can be bought for 4 Unobtanium Crystals (uC). This mine drops 3 pieces of coal every 4 seconds, or a coal piece every 1.3 seconds. This mine is the same size of the regular coal mine, but the ores that it spawns require 3x the conveyer space to obtain (the droppers can overlap). The only purpose of this mine is to fuel industrial mines.
