Functional regression models in rock breaking methods by means of explosives

摘要

Results of the research on getting technology in rock raw materials opencast mines, including main groups of raw materials, are presented. Basing on the realisation cycle measurements identification of the essential characteristics, determining the deposit mining technology, is carried out. The analysis determining statistical parameters for the particular kinds of rock in the form of: average value, median, modal value and conventional variation as well as interval limits of maximal and minimal realisations has been carried out. The general results are given in the from of empirical resolution of density and distribution function of the main parameters, particulary of web, stemming and unit explosive charge for the three main groups of raw materials: limestone, granite and basalt. Functional two-dimensional and multidimensional regression models, used for optimisation of the primary blasting methods for the particular groups of raw materials have been determined.
