Abstract
A scheme of a DTH air hammer is presented and the issue of reliability of a device with a three-stage hammer made according to this scheme is considered. The features of the bottom hole cleaning system of such devices are shown. The possibilities of using an elastic ring valve located at a larger stage of the hammer have been determined. The results of field tests of DTH hammers are presented.
