A miner pulls a cart full of coal, hacked from narrow shafts called 'rat holes' that radiate out from a central vertical shaft that extends from the surface. The miners must fill a large crane bucket before its raised to the surface. The miners work from 7am to 1pm and from 2pm to 7pm and sometimes later. They are paid for each full bucket and the money divided between all those working. There are approximately 5,000 privately owned coal mines in the region sitting on top of about 40 million tons of coal. Many use children, often trafficked, to work them under conditions that are hard and unregulated. The coal is dug out using primitive methods and basic tools.
