Abstract With the vigorous development of water conservancy, transportation, energy, and other infrastructure proj? ects in China, tunnel and underground engineering construction has entered a period of rapid and significant growth.First, the development of drill and blast construction equipment is introduced, elaborated in four stages: "manual","small mechanization", "single process large mechanization", and "full process large mechanization". Second, the current status and development trends of problems encountered during drill and blast construction, such as core recovery rate, overbreak and underbreak control, arch erection efficiency, rebound in wet spraying, and anchor grouting density, are expounded and discussed. The paper also proposes the future key development fields in construction technologies, including drill and blast construction equipment, collaborative management platforms, and green construction equipment. Finally, the paper looks ahead to the prospects of intelligent equipment and intelligent construction in drill and blast tunnelling, aiming to promote the development of China′s tunnel engineering towards unmanned, intelligent, informative, environmentally friendly, energy-saving, and sustainable goals.
