Hogan said the trooper charged her with obstruction. She said she was released on $2,500 bail.
Calls to the State Police and spokesman Sgt. Michael Baylous were not returned Saturday evening. A dispatcher said troopers were too busy handling the protesters to talk with a reporter.
The environmental-activist organization RAMPS -- Radical Action for Mountain People's Survival -- organized the rally, during which 50 protesters walked onto the Hobet Mine property, shutting it down.
"The government has aided and abetted the coal industry in invading environmental and mine safety regulation," Dustin Steele, a Matewan resident and protester, said in a prepared statement from the organization. "We are here today to demand that the government and coal industry end strip mining, repay their debt to Appalachia and secure a just transition for this region."
The organization kept the site of its protest under wraps until Saturday.
One protester, identified on the RAMPS website as Bryan Garcia of the Katuah Earth First organization, was in a tree, surrounded by four coal miners, the group claimed. The coal miners threatened to cut the tree down with a chain saw, although no saw was visible, according to the organization.
Among the more than 50 protesters were 10 people who locked themselves to a rock truck and dropped banners that read "Coal leaves, Cancer stays," according to a statement from RAMPS.
