Popis: The application range of remote drilling machines is described. The common shortage of these machines is the dependence of the blow energy transfer to the bottomhole on the bottomhole depth. Aimed to reduce the influence of this factor, it is proposed to use the mixed-type method of drilling with a downhole rock drill to be placed directly at the bottomhole. The key element of this method is a small-size DTH rock drill. The layout of the rock drill and its prototype testing results are presented.
