CONTROL METHOD Russian patent published in 2019 - IPC E21B44/00 G05B13/02 

FIELD: soil or rock drilling; mining.

SUBSTANCE: invention relates to shock enhanced rotary drilling and, in particular, to resonance enhanced drilling (RED). Method for controlling a resonance enhanced rotary drill, comprising a drilling module and a control system for controlling one or more drilling parameters of the drilling module, the method comprising steps of (a) applying one or more initial characteristics of the material being drilled, and/or one or more initial drilling parameters to the control system and/or to the drilling module, (b) measuring one or more current drilling parameters to obtain one or more measured drilling parameters, (c) employing the one or more measured drilling parameters as an input in the control system, in order to obtain an output from the control system, which output comprises one or more calculated characteristics of the material being drilled; one or more characteristics of the material being drilled comprises stiffness or effective stiffness of the material, (d) employing (i) the one or more calculated characteristics of the material being drilled, or (ii) one or more calculated characteristics of the material being drilled, and one or more measured drilling parameters as an input in the control system, in order to obtain an output from the control system, which output comprises one or more calculated drilling parameters.

EFFECT: technical result is higher drilling efficiency with limited wear and tear on the device to extend the life of the device, as well as more precise control of resonance enhanced drilling.
