This Thursday marks the eighth day since the collapse at a coal mine in Sabinas, Coahuila, in northeastern Mexico, which left 10 workers trapped.
State and federal authorities continue with rescue efforts that include water pumping works to free the entrances to the mine.
José Urbina, a cave diver based in the state of Quintana Roo, analyzes the rescue efforts and calls on the authorities to use their experience and equipment to save the trapped miners.
