Abstract
More complete extraction of minerals from subsurface by reducing their losses even more actualizes tasks of improving mathematical models of mining objects. Purpose of this work is to create geometric models of typical complex-structured blocks (CSB), which could be extended to real CSB. They are based on mining and geological models of virtual (typical) complex-structured ore blocks of bench, consisting of discontinuous continuous (first type) and dispersed ore bodies (second type). These blocks key parameters are isolated continuous and dispersed ore bodies characteristic points coordinates, ore bodies with host rocks contact line segments length, and ore bodies areas in CSB sections. They determine these objects mining and geological characteristics (ore saturation, block geological and morphological structure complexity). These characteristics are analytically interconnected with disparate ore bodies geometric parameters and admixed rock or lost ore layer size. They are the basis for CSB geometric models numerical values calculation methodology and mining and geological characteristics of ore bodies and whole block. Computer program for automated determination of geometrical characteristics of CSB by given initial key parameters of complex-structured blocks has been created. Example of calculation of these characteristics for typical complex-structured blocks is considered, and significance of research results in CSB development is shown. Proposed methodology of calculation of key characteristics of geometrical models of CSB is an information basis for making decisions on economical and ecological development of CSB of benches. Results of research can be used in exploitation of real complex-structured deposits to significantly reduce loss and dilution of minerals.
