Abstract

Over the last decades, deep drilling technology expanded fast. Newly created progressive technologies improved quality of drilling work and speeded-up the drilling process. Currently, 75-80 % drilling methods used world-wide are traditional, while 20- 25 % are new techniques. Slovakia is a little behind this trend: our utilization ration shows 95-98 % traditional drilling methods, compared to only 2-5 % new ones. Together with development of new deep-well boring technologies, new types of drilling sets for deep drilling are developed and modified (depending on applied techniques).These techniques use both mechanical and physical impact for drilling/crushing of rock. Many tests and analyses of these drilling/disintegration methods were carried out in the past. Here, we will concentrate on description of the work principle and utilization possibilities. Rapid growth in demand for energy and its consumption will be increasing farthest in spite of necessary economical measures, economical restructuring, and more effective use and other measures. It is primarily conditioned by raising growth of the world occupancy, process of the world industrialization and raising the living standards all over the world.
