Fourteen people including senior vigilance officers were trapped after a lift collapsed at the Kolihan mine in Rajasthan's Jhunjhunu district late last night. Of them, eight have been rescued so far from the copper mine of Hindustan Copper Limited. Efforts are on to evacuate the remaining six still trapped inside. Doctors at the site suggest all those who were trapped are safe. However, nine ambulances have been on standby outside the mine for any emergency.
