Rescue workers have now recovered 30 bodies after Saturday's underground explosion that killed 32 coal miners in northeastern Colombia.
Officials say crews will try to retrieve the remaining body Monday. One miner had escaped after the blast but died later in a hospital.
High levels of explosive and poisonous gasses in the mine slowed the work of recovering the dead.
On Sunday, Colombian President Alvaro Uribe traveled to Norte de Santander to assure family members that the government would closely follow the investigation into the cause of the blast.
