Abstract

A drill string for use with percussive type drills for rock drilling is described. The drill string has sections of drill steel in which a steel core, which acts as a transmission line for the force pulses generated by the hammer of the drill, is protected from scoring (as from rocks or adjacent metal objects) by sheathing which is attached to the core by resilient members to define a mass spring system in which the sheathing and pulse transmission member are dynamically isolated from each other at the repetition frequency of the force pulses. The sections are connected by coupling joints of the drill string. A breakout mechanism may be incorporated into each section to break out the joints, in which lugs extending from the core engage the sheathing during breakout to protect the resilient member during breakout. The resilient members are constructed so as to be provided with sufficient longitudinal and torsional stiffness such that during normal drilling the lugs are isolated from the sheathing and do not produce galling or other damage.
