China’s coal mines go driverless: Electric trucks work through -40°C, no pit stops

In Inner Mongolia, home to China’s largest coal reserves, a vast open-pit mine cuts deep into the earth. Clouds of dust hang over the site. Winters are long and brutal, with temperatures falling to minus 40 degrees Celsius (minus 40 degrees Fahrenheit). In the past, hundreds of truck drivers wore heavy winter gear to brave icy roads and frostbite risk as they hauled loads through the pit. Dense fog and extreme cold often made the work slower and more dangerous. Now, the mine is upgrading to autonomous electric trucks. These driverless vehicles can operate in severe weather without human operators in the cab. They also avoid the need for fuel stops, which keeps work moving with fewer interruptions. The shift shows how China’s coal industry is testing automation and electric power in some of its hardest working conditions.
