“…is process from microdamage to macrofracture has fractal properties [8]. erefore, many researchers introduced fractal theory to analyze the particle size change in the process of soft rock disintegration from multiple perspectives, calculated the fractal dimension to describe the disintegration process, and proposed a variety of fractal distribution models based on rock mass [9][10][11].…”

In order to study the influence of elevation on the slake durability index of the quartz mica schist, the quartz mica schist with different elevations on the east slope of the Manjiazhai open-pit mine is taken as the research object, and based on laboratory tests and statistical analysis, the variation of negative correlation between the slake durability index and elevation is obtained. The disintegration mechanism of quartz mica schist at different elevations is also discussed. The test results show that the disintegration characteristics of quartz mica schist at different elevations are related to its mineral composition, fissure channel size, and rock damage effect. As the slope height increases, the ratio of mica to quartz in the rock increases, and the greater the porosity of the rock, the more fissures in the rock, the greater the permeability coefficient, and the more obvious the change of effective stress of rock under osmotic pressure. At the same time, the higher the slope elevation of open-pit mine, the longer the weathering time of rock, the higher the cumulative damage of rock, and the lower the rock slake durability index. This study provides a new idea for guiding the research on the disintegration characteristics of similar soft rock slopes in the elevation direction.

“…The results of such calculations can further be processed, correlated with each other and visualized by obtaining data that can easily be superimposed on a geological map of a massif to draw a range of the observed transformations in the discussed rocks. In Earth sciences, the fractal dimension has long been used in the assessment of rock porosity (Chen et al, 2021;Gulbin, Evabgulova, 2003;Kincal et al, 2010;Lehmann et al, 2003;Martin, Reyes, 2008), geophysical and reservoir (Mohammadi et al, 2013;Zhengli et al, 2014), tectonic (Sły et al, 2014), and textural studies of rocks (Gerig et al, 2010;Singh et al, 2021;Voytekhovsky et al, 1997;Zheru et al, 2001). The correlation of the shape of rock-forming minerals in the context of the petrographic description of rocks is still quite poorly understood.…”

Аннотация. В статье описано применение метода оценки фрактальной размерности к исследованиям минералов и влияние вторичных процессов минералообразования на результат. Было исследовано 38 образцов, содержащих породообразующие минералы, из палеопротерозойской интрузии Мончеплутон, расположенной на северо-востоке Фенноскандии. Чтобы выполнить измерения и правильно интерпретировать породы, было проведено петрографическое исследование образцов с использованием поляризационной микроскопии, а затем измерена размерность фрактальной ячейки с использованием автоматизированного метода расчета сторон сетки, которая была наложена на микрофотографию, показывающую микроскопические изображения минералов. Полученный коэффициент фрактальной размерности коррелирует с формой исследуемых минералов в породе.Ключевые слова: Фрактальная размерность, породообразующие минералы, Мончеплутон, Северо-Восточная Фенноскандия.

“…Mudstone disintegration studies are mainly carried out by considering energy storage and transfer using statistics. For example, KINCAL [15] carried out a quantitative analysis of soft rock disintegration using the fractal dimension of particle sizes, a fractal dimension equation, and the fractal parameters to establish a model for soft rock disintegration. Miklusova [16] studied the surface area, volume, and particle sizes of debris from disintegrated soft rock, considered the changes in surface energy during disintegration, quantitatively characterized disintegration from the energy perspective, and established a model for energy transfer and dissipation for soft rock disintegration.…”

To identify the water softening mechanisms that caused landslides in Panzhihua Airport, China, property and saturation tests of the mudstones extracted from a representative landslide were proposed. In this paper, water saturation tests were carried out on samples of carbonaceous mudstone collected from the east side of the No. 12 landslide at the airport. A number of different analytical techniques and mechanical tests were used to determine changes in chemical composition, mineral assemblages, and mudstone structural characteristics, including shear strength, after the mudstone had been softened. Three kinds of changes caused by water and three mudstone softening stages are proposed. The results show that the water has a significant influence on the properties of the mudstone, so the stability of the mudstone in the watery period is a big threat to the upper structure. A model for water immersion mudstone strength softening is developed. The model incorporates a permeability coefficient, the hydraulic gradient, and time; the model can be used to determine the mudstone’s shear strength and internal friction angle. This study provides a reference for the study of rock softened by water immersion.
