down-the-hole (DTH) drilling - Opis:
- This paper addresses the issue of drillbits for drilling normal and large diameter boreholes with the use of percussion-rotary method. The most important elements of drillbits, i.e. sintered carbide inserts of different shapes have been described. The hardness of the drilled rock determines the shape of used sintered carbide inserts and the shape of the drillbit face. The cluster hammers, used for drilling large diameter DTH, have been also presented.
