Abstract: The inclination and depth of borehole are important factors to ensure blasting effect in the surface deep hole bench blasting.The workload of traditional measurement methods about borehole is extensive，which becomes a short board of digital blasting construction.Aiming at the above problems，the measurement method of artificial tape，sound wave and laser are discussed respectively based on borehole measurement experiment，including test principle，advantages and disadvantages，adapted condition and improvement measures of the three borehole measurement methods.The measurement methods based on sound wave and laser have the potential improvement and application space，and it can provide reference for the development of digital borehole measure in surface deep hole bench blasting.
