"I gave instructions to strengthen the entire rescue plan. [Rescuers] are pumping out about 290 liters per second, we will increase pumping, mining engineers are proposing to create something like a barrier between two mines to stop the water," Obrador said during a press conference.
The accident occurred in the Las Conchas coal pit in the municipality of Sabinas on August 3, when miners encountered an underground river during their work, which caused the flooding of the mine's well. One miner was able to get out of the coal pit safely, while ten others remain inside.
