INTERACTION OF A HELICAL BLADE OF A DRILLING TOOL WITH FROZEN GROUND by I. G. Martiuchenko, M. I. Zenin

“…The dependence of the destroyed soil volume and the relation of an obtained borehole diameter to a diameter of a destroying section of a helical blade according to the angle of bend of a helical blade radius at which its increment occurs is determined.Discussions and conclusion. It is established that a helical drilling tool performs a borehole drilling due to the tearing strain implementation, which makes it possible to achieve more efficient drilling and obtain a borehole diameter larger than a diameter of the destroying section of a helical blade.Financial transparency: the authors have no financial interest in the presented materials or methods. …”
