Abstract
Disclosed is a full-face shaft boring machine, a boring system and a boring method. The full-face shaft boring machine includes a cutterhead structure provided with an outer tapered surface structure protruding in a boring direction. The outer tapered surface structure surrounds an outer circumferential side of the rotation center of the cutterhead structure, and a radial cross section of the outer tapered surface structure gradually decreases in the boring direction; at least one receiving port for rock slag to pass through is formed at the taper top of the outer tapered surface structure and runs through the cutterhead structure in the boring direction; and a slag discharging assembly for discharging the rock slag is arranged on a side of the cutterhead structure away from the boring direction.
