Abstract
The design of a domestically produced DTH hammer for drilling holes in rocks of medium and high strength is presented. Using mathematical modeling method, the possibility of hammer operation at an energy carrier pressure of 2.4 MPa is proved. The results of DTH hammer prototypes testing in laboratory conditions and at mining facilities are presented.
