Mexican Labor Secretary Javier Lozano says the rescue phase has ended and the government will start a rigorous investigation into mine safety in Mexico.
The last body was found early Sunday and was that of a 38-year-old miner.
The blast Tuesday was so powerful it also seriously injured a teenager who was working outside the mine.
Mexican officials said it was caused by a gas buildup. The national mine workers' union said the mine's work force was not unionized and criticized the unsafe conditions in which Mexico's mines are allowed to operate.
