To get coal in Minecraft you will need a pickaxe. The pickaxe can be made of wooden planks, cobblestone, iron ingots, gold ingots or diamond gems. You craft it by doing 2 sticks up the middle and 3 of whatever material along the top row in a 3x3 grid (right click a crafting table). Coal is obtained by destroying coal ore - it is stone with black markings in it. Destroy with the pickaxe to get the coal. You can then make torches with it or use it as a furnace fuel.
A single piece of coal can perform 8 furnace operations in minecraft 1.6, so that means 8 pieces of cobblestone.
