摘要

The future of coal looks like an ice-cream truck parked half a kilometer down a mine shaft in China’sShanxi province. The yellow-and-white vehicle is equipped with a 5G router from HuaweiTechnologies Co. to gather data for the mine’s control center, where technicians monitor highdefinitionfeeds on a screen the size of a two-story house. They’re tracking temperature andmethane concentrations while keeping watch over the black lumps zipping along conveyor belts onthe way up to waiting trucks.
