| الوصف: | The article presents the computer simulation results for the stress-strain state of the lining sections of the shaft No. 1 of mine 3 of JSC Belaruskali that were obtained using visual and instrumental investigation of the mine lining state. The loading parameters of the shaft take into account the specific feature of the lateral pressure calculation in the considered location. This means that the shaft intersects vertically rocks different in their physical and mechanical properties. Computer simulation of loading of the most problematic vertical mine shaft sections observed by the lining examination results was performed using the Static Structural component of the ANSYS Workbench engineering software package. Distribution diagrams of longitudinal normal, shear and von Mises equivalent stresses in the vertical mine shaft lining are obtained for the design and residual values of the cast-iron tubing thickness. A comparative analysis of the mine shaft residual bearing capacity for various parameters of the lining elements was carried out. Based on the computer simulation results, the conclusions were made on the bearing capacity of the shaft No. 1 of mine 3 of JSC Belaruskali and the recommendations for a further safe operation of the mine shaft were suggested. ; Представлены результаты компьютерного моделирования напряженно-деформированного состояния участков крепи ствола № 1 рудника 3 ОАО «Беларуськалий», выполненные на основе визуального и инструментального обследования состояния крепи. Параметры нагружения ствола шахты учитывают особенность расчета бокового давления на рассматриваемом участке, заключающуюся в пересечении вертикальной выработкой различных по своим физико-механическим свойствам горных пород. Компьютерное моделирование нагружения части ствола, в которой наблюдаются наиболее проблемные по результатам обследования крепи участки, выполнено с использованием компаненты Static Structural инженерного программного комплекса ANSYS Workbench методом конечных элементов. Получены диаграммы распределения ... |
