Abstract

1415981 Boring earth &c KOOLAJ ES FOLDGAZBANYASZATI IPARI KUTATO LABORATORIUM 10 Jan 1973 [11 Jan 1972] 1260/73 Heading E1F An earth drilling tool has located in the flow path 3 of drilling mud a vibration exciting element 4 and a cavity resonator 5, tuned to produce an ultrasonic frequency. The ultrasonic vibrations increase the efficiency of rock breaking, and the frequency is chosen to be equal to, or a multiple of the natural frequency of a rock breaking element 6. A nozzle 7 provides for jetting. Specification 1415982 is referred to.
