The results of developments in the direction approbated:

- In the quarries Southern, North and Central Inguletskogo MPCs and in the quarry of the company “Mitall Steel”. Implementation in these quarries emulsion explosive mark of Ukraine provided decreasing self-cost of blasting operations on 10-15%, increasing productive of excavators on 20%, decreasing dust formation on 60-62%, gas-formation on 65-68%, decreasing output of nitrates in the stratal water in 2,5 times. Actual economical efficiency from implementation Ukrainet at the MPCs more than 25 486 million UAH.

- In the quarries of non-metallic building materials of Ukraine (“Kremenchygskogo” “Quartz”, OAO “Nikitovskiy granite quarry”, Pervomaivsky granite and crushed-stone quarry of the State Concern “Inmakom” republic of Moldova, Volovetskoe cooperative enterprise “Agrodostroy”, AOZT UMP “Hydroenergostroy” quarry, OAO “Pervomaisky quarry “Granite” and others), implementation of technology of blowing by borehole charges in rock minerals allowed decreased lines of sanitary protection zone and safely extraction of abandoned resources of minerals close to residential buildings and constructions.

- During building operations hydrotechnical constructions at the Tashlikskoy GNES technology of blowing and optimization of parameters borehole charges allowed in short terms come to an end of construction and bring in exploitation.

During 2010-2011 years by department of “Surface Mining” were carrying out 3 scientific researches and 9 cost-accounting scientific research and planning works on the general sum over than 1,2 million UAH.
