Research on Geological Survey of Carbonaceous Rocks in Guangxi and the Law of Fractal Evolution of Disintegration

Abstract

In order to reveal the disintegration characteristics and microscopic mechanism of carbonaceous rocks, the composition, composition and systematic classification of carbonaceous rocks were discussed, and the disintegration resistance test, electron microscope scanning test and TOC total organic carbon content test were carried out. The development mechanism of the resolution index, and at the same time based on the fractal theory to study the law of fractal evolution at the time of disintegration damage. Subsequently, the effect of the composition of the carbonaceous rock on the disintegration characteristics is analyzed from a microscopic point of view, and finally the fractal characteristics of the carbonaceous rock (fractal dimension) Establish a connection with the micro-influencing factors and interpret the microscopic nature of the disintegration characteristics of carbonaceous rocks. The results show that: 1) The disintegration resistance index of carbonaceous rocks gradually decreases and tends to stabilize with the increase of the number of disintegration tests; 2) describe the rock The fractal dimension of the disintegration damage is 2.5~2.8, and the corresponding total organic carbon content of the TOC is 1.45~3.32%, which has a good positive correlation; 3) The mechanism of the relationship between the disintegration characteristics of the obtained carbonaceous rock and the microscopic composition It can lay a theoretical foundation for the classification of carbonaceous rock systems.
