Abstract
Considering this problem, an attempt is done by this paper to determine consumtion of drilling tools for the work environment in the mine Žuta Prlina, experimentally 'in site' during the short blast holes drilling. Data are grouped into three groups depending on the pressure of compressed air and water. In each group, particularly the impacts of somel elements of bit blade are observed and their impact on consumption the drill bit.
