Calcium carbide is a chemical compound that reacts with water to produce acetylene gas, which is combustible and is used in mining lamps. The gas also encourages fruit growth in plants such as pineapples. Calcium carbide is used in making steel, PVC, signal flares and some old-fashioned fireworks, in addition to mining.
Calcium carbide is man-made. It is produced in a 2000º electric arc furnace. There is no "natural source" for the substance. You cannot go dig it up somewhere. If you could, it would be a clear or bluish crystal, rather soft, with an unpleasant odor.
I would go into the science of it in more depth, but the foregoing answers the question asked and you don't need to be a chemistry major to understand it. :)

I'd be very surprised if miners still use acetylene lamps! They were used by miners in gas-free ground (usually metal-ore mines and underground stone quarries) many years ago. They were used by many cavers until electric lamps (usually ex-colliery) became common in the 1960s, then had a brief flurry of popularity again in the 1980s-90s when developments in caving techniques and equipment meant the electric mining lamps were no longer safe to use due to their liquid electrolytes . Now acetylene lamps are pretty well obsolete, displaced in mining and in caving by l.e.d lamps; and suppliers of calcium carbide are becoming hard to find.

Are tungsten carbide rings breakable?
Yes, tungsten carbide rings can shatter when enough force is applied to the ring. These rings are very hard and highly scratch resistant. This also means they are brittle so you can break them with a hammer or a pair of vice grips. Source: LarsonJewelers.com
