At the Choa Saidan Shah coal mine, workers dig coal with pickaxes, break it up, and load it onto donkeys to be transported to the surface. The mine is in Punjab, Pakistan's most populous and richest province, but most of the miners come the poorer region of Khyber-Pakhtunkhwa, to the northwest. Employed by private contractors, the miners work in teams of four, with each team earning about $10 a day to be divided among them. (Photos by Sara Farid, Reuters, Origionally published July 30, 2014)
