China is using “smart” technology to try to improve its safety record in coal mines, as part of a push by the National Energy Administration to bolster output and stem frequent accidents and collapses.
Smart-mine sensors monitor aspects such as gas buildup and flooding or ventilation levels, and set off an alert if any reach a dangerous level. The sensors, located inside the mine and on carts and tools, transfer the data via 5G, allowing for real-time monitoring by a central command.
