Information × Registration Number 0212U002501, 0111U005128 , R & D reports Title The definition peculiarities of the change of properties of mining rocks and the state of rock conducting the mining working and taking effect of the different ohysical fields popup.stage_title Head Perepelitsa Valentin Grigorievich, Registration Date 05-03-2012 Organization The Polyacov Institute of Geotechnical mechanics of NAS of Ukraine popup.description2 The object of researches is sedimentary rocks of different lithification stages and processes that proceeds during rock breaking by dynamic loadings. The purpose of work is determinafion of the structural-mineralogical special features in sedimentary rocks complexes that influences on mining and development of scientific fundamentals of the methods blasting and shock energy transmission operation during breaking of dence mediums for reduce losses of the mineral products and negative influence on surroundings. Methods of studies are the complex of geological-geophysical methods siltges study, complex of geomorfological, thermometric, geomechanical, mining-geological and geodynamic and also petrophysical methods; scientific analysis and generalization of information in the field of rock breaking under blasting and shock loads, methods of mathematical physics and solid mediums mechanics, experimental of study the breaking and shock loading action in laboratory and ground terms. The novelty of the executed work is the objective law siltges compression establishment that consists in its step changing in 1,5-2,0 terms on every stage of lithogenesis with own structural-mineralogical parameters and petrographic features, that determine rock properties,and also in establishment obyective laws of breaking dence mediunis under dynamic loadings depending on energy value, that is transmitted to breaking solids and energy transmission conditions.
