| Abstract |
In this paper, a model is developed for the geomechanical state of coal-rock mass containing the following: the seam and the hydraulic fracture for effectively applying a method of directional
hydraulic fracturing of solid rocks. The model is based on the provisions of solid mechanics and Griffiths–Irwin linear fracture mechanics and is implemented using the method of boundary integral
equations. Using the model, a large-scale computational experiment was carried out for specific mining and geological conditions of a coal deposit. Based on the analysis of the obtained results, a number
of features in the propagation of the crack were identified. |
