煤岩压裂混沌特性关联维数Lyapunov指数CBM Fracture Chaotic Characteristics Correlation Dimension Lyapunov Index



This electronic fracture of coal-rock fracture system evolution is a complex nonlinear dynamic characteristic of the coal-rock damage caused by fracturing micro-fracture. In its fractal evolution process, the information such as the crack tip stress field and number of micro cracks changes, needs to determine the change rule of rock crack tip stress field and the number of micro cracks in the fracturing process, i.e., the prediction of rock mass fracture scale. The paper reveals the essence of chaotic characteristics of coal-rock cracks evolution from correlation dimension and Lyapunov index, study the chaos characteristics in the process of fracture network evolution and analyze the rule of chaotic characteristics of fracture network evolution changing with the fracturing process.
