Fifteen men were working inside the Pinabete mine in Sabinas, Coahuila, about 70 miles (115 kilometers) southwest of Eagle Pass, Texas, on Aug. 3. A wall of water from an abandoned mine next door — and possibly wastewater pumped in from a nearby town — filled the single shaft about 40 meters (yards) deep. It blew out so many wooden supports that they have formed floating barriers to rescue crews. Five workers managed to escape as the mine flooded, but there has been no contact with the rest.
