The Damage Mechanics Model of the Wellbore Surrounding Rock Based on Fractal Theory
In order to describe the mechanical characteristics of CBM wellbore surrounding rock more accurately, the article establishes the CBM wellbore surrounding rock mechanics model based on the fractal theory. According to the pores of CBM surrounding rock and the characteristics of mass fractal, people find the macro fracture and micro fracture damage characteristics and build the relationship of any scale coal strength, damage variable and fractal dimension. According to the numerical calculation method of the surrounding rock stress, people find the surrounding rock stress calculation method and the damage distribution model of the pore fractal model and fracture fractal model.
