The Fractal Characteristics of Wall Rock Crack in the Soft Rock Roadway and Study on Theory of Loose Ring

Abstract:

Rock mass is an irregular and disordered geological body. Quantitative study on rock fracture has always been an important part in the long-term research of rock mechanics. It has taken the soft rock roadway as a carrier which is located in the Mine of Gaojialiang in Ordos area. Fractal geometry is adopted in the quantitative analysis of the wall rock crack in the soft rock roadway. As the result shows, the distributions of wall rock crack in the soft rock roadway are fractal. Fractal dimension D reveals the properly distributed statistical characteristic values and D value curves with different depths determine the ranges of loose ring, which provides reliable theoretical basis for the loose ring theory.
