摘要
兖州煤田矿井在回采的过程中,发生了多起大能量矿震事件,影响了井下的正常生产。通过研究原岩应力重塑影响下断层应力和能量的演化规律,进而对原岩应力破坏重塑后诱发断层构造型矿震过程进行了解释,最终揭示了原岩应力和构造应力耦合作用下矿震发生机理。
During the stoping process of Yanzhou Coal Field,many large-energy mine earthquakes occurred,which affected the normal production of underground mines.By studying the evolution law of fault stress and energy under the influence of original rock stress remodeling,the process of induced fault tectonic mine earthquakes induced by the original rock stress damage and remodeling is explained,and finally revealed that the ore rock under the coupling effect of original rock stress and tectonic stress Mechanism of earthquake.
