The paper reviews the existing technologies and equipment for drilling in rocks and soil with adjustable path of drillholes. The author describes a new method of percussion drilling and its application prospects. A lab-scale testing installation for physical simulation of rock fracture in drilling by the new method is presented. The force and impact characteristics required for the method implementation are updated.
