After defining the parameters describing the quality of blasts in tunnel driving--the pull efficiency, the overbreak and the HCF factor (the ratio of thee observe length of half cast on the tunnel wall to the total drilled length of the contour holes) --the paper examines the influence of the qualit

Keyblock has been received a lot of attention in underground engineering because it loses its stability first after excavation. Block theory originally proposed by Shi could not build the geometric characteristics of keyblock and explain how to determine the precise locations of keyblock. Therefore,
