Miner Juan Briones, 35, rests after ending his shift at the coal mine where he works, in Sabinas, Mexico August 19, 2022. Briones' taut, lean frame belies the strength he possesses to work up to 8 hours a day, wielding a pneumatic air gun to blast the rock and a shovel and cart to lug coal through underground tunnels.
