Some of the 17 miners trapped in an elevator shaft at an upstate New York salt mine have been rescued and crews were continuing to work early on Thursday to free the remaining miners, officials said.
The Tompkins County Department of Emergency Response said in a Facebook post that eight of the 17 miners had been rescued.
The miners became trapped about 800 to 900 feet (244 to 274 meters) down around midnight local time when a lift malfunctioned at the Cargill Salt Mines in Lansing, a town of about 11,000 people near Ithaca, the department said.
Emergency crews have been in contact with the miners via radio and there were no known medical emergencies, local broadcaster WTEN-TV reported.
Technical Rescue experts and equipment have been called to the scene to help rescue the workers, emergency officials said.
According to Cargill's website, the Lansing mine processes approximately 2 million tons of road salt that is shipped to more than 1,500 locations throughout the northeast United States.
