China Develops Xianglong, First Hybrid Tunnel Boring-and-Blasting Machine
China has developed the world's first hybrid tunnel boring-and-blasting machine named Xianglong, designed to improve tunneling through complex geological conditions. Jointly created by Tsinghua University and China Railway Group, the 4.5-meter-diameter machine integrates excavation with drilling and blasting, boosting hard-rock digging efficiency by 30%. This innovation addresses delays and safety risks caused by switching between traditional boring machines and drill-and-blast methods. The machine will undergo field trials at a power plant in Henan province.
