Abstract：A quantified relationship between shaft drilling parameters and drilling machine performan -ces always is a weak link in a research on the shaft drilling engineering. With a quantified analysis ,a introduction on a conception of a rock breaking specific power and a derivation calculation conducted , a quantified relationship between the shaft drilling parameters and drilling machine performances was provided.In the engineering practices ,the research on the quantified relationship could be applied to optimize the parameter design on the shaft drilling technique and to improve the actual application effi ‐ciency of the drilling machine.Based on the variation conditions of the shaft drilling technical parame ‐ters ,the level of the drilling machine performances played could be predicted ,the drilling machine acci‐dent occurred could be prevented and the construction target could be scientifically and rationally real ‐ized.
