摘要	The design parameters of PDC bits for rock drilling trolley have not been studied in depth and it is lack of theoretical research basis. So the service life of the bits for tunnel tunneling construction cannot meet the design and application requirements. Taking three-arm rock drilling trolley as the experimental platform, the key parameters of PDC bit crown profile shape, caster angle, cutting tooth size, tooth arrangement density, inner cone angle, outer swing angle and crown top shape for rock drilling trolley are designed by combining the optimum design method, empirical numerical value and experimental correction. The key parameters were optimized and improved through a set of manufactured bits, and a set of drills were manufactured again for the following experiment. The experimental data in second stage shows that the broken and drop defects of the improved bits are greatly reduced. The drilling depth is significantly increased, and the service life is also improved, which meets the requirements of design and operation. © Published under licence by IOP Publishing Ltd.
