Almost all over Ukraine in the bowels of the Ukrainian crystal shield is more than 500 million m3 of explored
reserves of high quality natural building and finishing stone. Of particular interest are granite deposits as the main
strategic raw material for the construction of industrial, defense and civil structures, roads, runways, airfields,
transport tunnels, subways and more. Today, more than 150 quarries in Ukraine extract valuable raw materials for
the country - natural stone. At the same time, given the high strength and abrasiveness of granites, their extraction
is extremely complex, expensive, time consuming. There are no machines that could directly extract strong granite
rocks of volcanic and metamorphic origin. To ensure the required volumes of granite mining, it is necessary to pregrind the monolith of the rock, which is carried out by drilling and blasting. These complex technological operations
provide powerful drilling rigs that perform drilling work in strong and very strong rocks [1].
In the presented researches the basic indicators influencing efficiency of drilling rigs on quarries of Ukraine
are analyzed and established. Rational methods of rock destruction for specific geological conditions of a mining
enterprise are considered, substantiated and recommended. Optimization of drilling efficiency and productivity was
performed by choosing the method of destruction, hardness of rocks, type of drilling machine and parameters of
tools for destruction of rocks [2]. The calculation method presented in the work allows to limit the amount of dust
pollution depending on the speed, depth of drilling, distance from the well for blasting, which will control the optimal
modes of operation of the drilling machine and drilling modes. The obtained research results confirmed the
correctness and efficiency of new innovative systems for drilling hard rocks in the quarries of Ukraine.
