Rescuers are seen at a small coal mine belonging to Linli Coal Mining Co. Ltd. in Shizuishan City, northwest China's Ningxia Hui Autonomous Region, Oct. 11, 2016. Two workers remain missing but search efforts have been suspended two weeks after an explosion killed 18 people at the coal mine in Ningxia, rescuers said Tuesday. The on-site rescue headquarters decided not to continue the search efforts due to the increasing risk of secondary disasters and the fact that the two missing miners could not possibly have survived.
