Distraught relatives protested and demanded answers Sunday two days after a collapsed dike in eastern China flooded two coal mines, leaving 181 workers missing and feared dead. State media said the breach in the dike in Shandong province early Sunday had been closed and pipes and high-speed pumps installed, but gave no indication if there were any signs of life. The Huayuan Mining Co. mine flooded Friday afternoon when the Wen river burst a dike, sending water pouring into a shaft and trapping 172 miners, Xinhua and state television said. Nine more miners were trapped when water poured into a nearby mine shaft. Both are nearly 600 kilometers (370 miles) southeast of Beijing.
