The assessment came Wednesday, hours after the bodies were pulled from the pit in the state of Coahuila. Authorities say a methane gas buildup caused the explosion, which was powerful enough to severely injure a teenage boy working outside the facility. Mexican President Felipe Calderon has ordered the attorney general's office to open an investigation into the blast. The mine had been in operation since last month. Local news reports have said the facility belongs to the mining company BINSA. In 2006, an explosion at another mine in the state left 65 miners dead. The bodies of most of the victims in that accident were never recovered. .
