Study on Microscopic Characteristics and Physical and Mechanical Parameters of Carbonaceous Rocks

Abstract:

In order to study the distribution of carbonaceous rocks in Guangxi, and reveal the microstructure of carbonaceous rocks, and explore the laws of physical and mechanical properties of carbonaceous rocks, and study the characteristics of carbonaceous rocks, the Regional division of the typical carbonaceous rocks in Guangxi was carried out. Subsequently, an electron microscopy scan test was conducted to analyze the microstructure characteristics of carbonaceous mudstone, shale and limestone. At the same time, the mineral composition of the carbonaceous rock, the chemical composition test was analyzed, and the physical and mechanical parameters test was conducted. Finally, the microscopic classification of carbonaceous rocks was linked to the physical and mechanical parameters. The results show that: (1) Guangxi carbonaceous rocks can be divided into three typical areas: Hechi District, Baise District and Liuzhou District. (2) The microstructure of carbonaceous limestone in Guangxi was mostly scaly, the mineral crystals of carbonaceous mudstone microstructure were mainly petal-like, and the clay minerals of carbonaceous shale microstructure was striped. (3) The microscopic chemical elements of Guangxi carbonaceous rocks were mainly carbon, silicon, and mineral components were mainly illite, and the illite content was linear with density.
