Abstract

In the work the task based on the model of the crystal structure of rocks develop a method of evaluation of their mechanical properties, including the tensile strength of the rock σсж and elastic modulus E. Model of the crystalline structure of matter based on ionic bonding, and for much of the rocks, such as magnetite. Cubic crystal lattice of magnetite formed oxygen anions O2-, which are connected by iron cations Fe3+ and Fe2+. Based on the model of the crystal structure of matter we developed a method of evaluating the mechanical characteristics of rocks, including tensile strength and elastic modulus of the rock. Predictive estimate the mechanical characteristics of the rocks on the proposed method makes it possible to exclude the adoption of further grave error technological solutions for project work in mining. For considerable part of mountain breeds, including and for magnetite, on the example of which the applied value of the method worked out by authors is shown, ionic connection is characteristic between atoms [8,9]. In the crystals of breed there is ionic connection between positive and negative ions. Ions form a crystalline grate due to that the coulomb pushing away less than, than coulomb attraction between the ions of opposite sign between the ions of one sign. The prognosis estimation of mechanical descriptions of mountain breeds on the offered method allows to eliminate the acceptance of rough erroneous technological decisions at project works on mining, to shorten the period of first-minings on planning of mountain enterprises.
