Systematic analysis of structural changes in the blasted and shipped rock mass at stone pits of OJSC “Uralasbest” in
development dynamics of Bazhenovsky field for twenty years had been made. Statistical evaluation of variation in time
and spatial variation of conditions and indices of rock massifs blasting disintegration at the chrysotile-asbestos pits in the
dynamics of their development has been fulfilled with the help of systematic analysis of statistical series, the levels of
which are formed under the complex influence of different factors and chances. Tendencies have been determined
of asbestos ores of different varieties extraction volumes change and rocks suitable for building materials production.
Regression relationship between the amount of excavation of rock and ore with increasing depth and spatial parameters
of the quarries has been established. The characteristics of physical and mechanical properties of ore-bearing rock and
waste rock, suitable for the manufacture of crushed stone and construction materials are introduced, as well as the
predetermining parameters and the efficiency and drilling and blasting complex at the open pits.
Key words: asbestos stone-pits; rock; asbestos ore; blasted rock mass structure; blasting disintegration of rock mass;
statistical evaluation; the volume of the extraction.
