Mehr News Agency has an excellent photo essay on the coal miners working at the Tabas coal mine in central Iran.
The miners work at a depth of 300 meters in two shifts of 6 hours per day and are hired on a contract basis.
Pay is 400 thousand tomans (about $200) per month and conditions in the mine appear to be fairly rudimentary.
As Western sanctions continue to bite Iran has been ramping up domestic coal production.
The country is targeting hard-coal production of 5 million tonnes this year from less than half that three years ago.
