FX will open the third season of its documentary series "30 Days" by sending creator Morgan Spurlock underground.

In the first of two installments Spurlock will participate in, he'll return to his home state of West Virginia and work in a coal mine for a month. He'll work both above and below ground in Pineville, W. Va., and live with a mining family. The show is scheduled to begin its third season on Tuesday, June 3.

Other episodes of the series, which puts people into unfamiliar and uncomfortable situations for 30 days, will deal with same-sex parenting, living in a wheelchair, animal rights and life on an Indian reservation. Spurlock will also take part in the latter episode, living with members of the Navajo Nation in New Mexico.

As with previous seasons, most of the other episodes will involve everyday folks putting themselves in radically different surroundings, such as a gun-control advocate who will live with a hunter and gun collector and work in a firearms store. In the "30 Days in a Wheelchair" episode, though, the participant will be former NFL cornerback Ray Crockett, who won two Super Bowls with the Denver Broncos and will experience what it's like to lose the use of his legs.

The series is FX's most successful unscripted show. Last season "30 Days" averaged about 2.4 million viewers per week over multiple airings.
