Estimation of mountain range cracks through the method of cracks fractal dimension determination

The purpose of this article is to estimate fracture-based method for the determination of rock mass fractal dimension on the example of Inguletsquarry. Statement of the main material. For research plots of maximum pit were selected as excellent for the factor fracture due to use estimation by the different methods the outline of the boardside in the conduct of mining operations. Described the essence of the fractal approach method and its use for solving problems of geomechanics, namely: to evaluate the fracture of the mountain massif via the determination of the fractal dimension of the cracks at the open pit. The most typical failure mechanisms in the massif (referring to the different methods of blasting) and based on the calculation of the fractal dimension of the cracks, which are located in the rocks. Built dependency graphs of the rock massif structural weakening from its fractal dimension for different values of the scale factor. The scientific novelty of the obtained results lies in the specification of the rock massif structural weakening coefficient by determining the fractal dimension of the board. Conclusion: the results of the work are based on the following statement: comparison of the obtained results with the data of calculations of the structural weakening coefficient without taking into account the fractal dimension for the areas of the sides Inhulets quarry is designed in the traditional way shows that the use of the method of calculation structural weakening coefficient, given the fractal dimension allows to specify its value by 5…10 %. Comparisons of the obtained values of the coefficient of structural weakening showed that the use of the traditional method of contour blasting does not lead to a significant increase. The degree of violation of the contour array compared to its natural fracture (increased by 7.1 %).
