Влияние изменяющихся горизонтальных напряжений в массиве на состояние крепи стволов

Влияние изменяющихся горизонтальных напряжений в массиве на состояние крепи стволов

Abstract

This article presents results of the research and calculations performed by the Institute of Mining of the Ural Branch of the Russian Academy of Sciences in the underground mine of Gaisky Ore Dressing Plant. The observed phenomenon of expansion and contraction of the Earth occurring in sync with easily tracked changes of the Sun’s size requires further examination and precise definition of correlation dependences. The article shows calculations and measurements of stresses in shaft supports which depend not only on the physical and mechanical properties of solid rock, but also on the time of shaft sinking and stops in the construction of the support for a period while concrete gained its full strength. There is a risk of destroying the integrity of shaft supports.

Представлены результаты исследований на подземном руднике Гайского ГОКа и расчетов, выполненных в Институте горного дела Уральского отделения РАН. Выявленное явление расширения и сжатия Земли, происходящее синхронно с легко отслеживаемым изменением размера Солнца, требует дальнейшего исследования и уточнения корреляционных зависимостей. Приведены расчеты и замеры напряжений в крепи стволов, которые зависят не только от физико-механических свойств пород массива, но и от времени проходки ствола и остановок при возведении крепи на время, за которое бетон набрал свою полную прочность. Возникает опасность нарушения целостности крепи стволов.
