The quantitative method of qualitative mining spatial information based on fractal theory
As a kind of widely distributed and complex phenomenon, fracture structure is a main factor considered in management of safe production in mine, and is also a main cause for safety accidents befalling in mine. Almost all former descriptions about fracture structure belong to qualitative classifying, lacking of quantitative approaches, and are influenced by certain subjective factors. As a result, the acquired information about fracture structure is weakened and the accuracy of safety accidents prediction and forecasting in mine is affected. Fractal theory is a new effective theoretical approach to researches on nonlinear problems whose fractal dimensions represent the magnitude and overall complexity of spaces occupied by graphics. As quantitative indices describing the complexity of fracture structures, values of fractal dimensions can synthetically reflect the quantity, magnitude, combination mode, and formation mechanism of fracture structures. In brief, they can quantitatively describe the characteristics of fracture structures, reveal adequately the information latent in fracture structures, and provide information supports to safety accidents prediction and forecasting in mine.
