摘要
Based on the field data of geological structures and occurrences of rock burst in Tangshan mining area, three-dimensional fields in coal bed and its surrounding rock were modeled and analyzed under different tectonic stress conditions by using numerical modeling software FLAC3D. The results show that tectonic stress has obvious influence on the distribution of stress field and energy field in coal bed and its surrounding rock. Under high structural stress conditions, high horizontal stress is the source of force and elastic strain energy stored in coal bed and its surrounding rock is the source of energy to induce to rock burst during coal mining.
