Computer modeling for the decision of mining geomechanics tasks

Software SIGMA. Modeling of stressed-deformed state of rock mass.
Example of calculations of stresses for normal and vertical component at mine lower levels:

Software possibilities: - Modeling of stressed deformed conditions of rock mass taking its heterogeneity as applied to plane strain into consideration; - Determination of the areas of possible mass destruction and plastic flows; - Evaluation of influence of stresses plastic relaxation. Practical implementation: Modeling allowed to determine rational and safe order of working off of steeply dipping ore bodies at JSC "Kazzinc" and "Kazakhmys corporation" deposits.

Software "BORT". Calculations of optimal and safety parameters of pit slopes.

Display view and basic software windows:

Software possibilities: - Determination of slopes load and its steadiness safety factor; - Determination of basic calculated parameters in the mode of automation search or in the mode of detailed research; - Dynamic conclusion of main calculation results reasoning. Practical implementation: Substantiation of safe and optimal slope angle of Shemonaikhinsky, Nikolaevsky and Suzdalsky pits was performed.

Computer modeling for the decision of tasks of metallurgical processes optimization

Example of metallurgical computation: dependence of coke consumption during the process of blast smelting on air-blast temperature upon various oxygen enrichment rates (O2 content in air-blast is 21, 23, 25, 27 and 29%).

Mathematical models and model analysis of metallurgical processes

Thermodynamical modeling of metallurgical processes is performed on the basis of elements chemical potential application. Within the framework of this approach it is possible to extend the range of tasks which are solved by means of thermodynamical modeling method.

Works are performed in the following directions:

• Thermodynamical modeling of metallurgical processes with automated analysis of the process technological parameters on the basis of assigned criteria of oxidation-reduction conditions of the process taking reagent and heat parameters into account.
• Thermodynamical modeling of the processes with the application of flexible modeling system allowing considering particularities of physical-chemical transformations during the process, which are determined by instrumentation of the process and particularities of material feeding to reaction zone.
• Computations performing and development of the adapted software systems for processes optimization upon changes in feed composition or in electrotechnical mode of the processes realization.
