BEIJING (AP) â¿¿ Three miners in China have been rescued after spending two and a half days trapped underground because of flooding in a coal mine that killed three of their colleagues. Xinhua News Agency says the three were lifted to safety from the mine in Guizhou province's Weng'an county early Monday. They have been hospitalized in stable condition. Three other miners remain missing. The mine flooded at around 10 p.m. Friday, trapping nine miners. Rescuers on Sunday had been waiting for the water level to recede before entering the shaft. Xinhua says police have detained eight people in the ongoing investigation. China's mines have long been the world's deadliest. Safety improvements have reduced deaths in recent years, but regulations are often ignored and accidents are still common.
