A coal rock is a rock that contains coal. Players with a Mining level of 30 can mine coal rocks with a pickaxe, granting 50 Mining experience. Coal rocks can be found in numerous mines throughout RuneScape, most abundantly in the Mining Guild.
On rare occasions the rock may give an uncut sapphire, emerald, ruby or diamond.
Coal is used in combination with ores such as iron, mithril, adamantite and runite to smelt bars in a furnace to create metallic armour and weapons with Smithing.
One of the best ways for members to acquire coal is through Motherlode Mine. Alternatively, members could also use an Ardougne cloak and Amulet of glory to get to and from South Ardougne Mine, which has some coal and several iron rocks.
Free players, on the other hand, have access to the Mining Guild (requires 60 Mining), South-Western Wilderness Mine (in level 9 Wilderness), or Hobgoblin Mine (in level 30-35 Wilderness). All Wilderness locations are dangerous especially going deeper where player killers are always on the prowl, so take necessary precautions, and never bring anything you can't afford losing.
Wearing either mining gloves or expert mining gloves grants a 40% chance for the rock to not deplete upon mining coal, allowing you to mine an additional coal before depleting.

Pre roll drops[edit | edit source]
A gem table rolls before the main drop table.[1] There's a chance to receive nothing here so that players can receive no items from a rock even if they are guaranteed to receive an ore in the main drop table.[2] The table gets more likely to be rolled if the player has a glory amulet equipped: the probability grows from 1/256 to 1/86.[3]
