摘要：Over the past years, deep drilling technology developed quickly. New technologies better quality of drilling work and accelerated the drilling process. At present, 20-25% are new techniques while 75-80% drilling methods used worldwide are traditional. Slovakia is quite at the rear of this tendency: our utilization ration shows 95-98% traditional drilling methods, in comparison to only 2-5% new ones. Advancement of new deep well boring technologies causes the evolution of new types of drilling sets for deep drilling (depending on applied techniques). Techniques used have a mechanical and physical impact for drilling of rock. Several tests and analyses of disintegration and drilling methods were performed over the last years. The article focuses on a description of the working principle and utilization possibilities.
