Abstract

The impact velocity and impact frequency of the hammer piston of a percussion rock drill are vared in incremental steps in order to find the maximum penetration rate. The frequency and impact velocity are so varied that the impact power is kept substantially constant all the time. A micro-computer is used to control the process.
