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.

摘要

本文针对煤岩体的地质力学状态，建立了以下模型：煤层和水力压裂，有效地应用了定向压裂固体岩体的方法。该模型基于固体力学和Griffiths-Irwin线性断裂力学的规定，并使用边界积分方程法实施。使用该模型，针对煤炭矿床的特定开采和地质条件进行了大规模的计算实验。在对获得的结果进行分析的基础上，确定了裂纹扩展的许多特征。
