| 摘 要： | 为了保证断层附近回采工作面的安全生产,必须了解该断层对工作面的采动应力分布规律。通过数值模拟,分析研究断层附近的回采工作面采动应力分布规律。结果表明:断层的存在不仅影响到应力峰值,而且影响到支承压力分布形式和分布范围,使得应力峰值向煤壁转移,应力分布范围减小。

| Abstract: | In order to ensure the safety production in working face affected by faults,it is necessary to fully understand the distribution rules of disturbance stress.In this paper,the distribution rules of disturbance stress are analysised by using the numerical simulation.The results indicate that,the faults affects the stress peak,which also affects the distribution form and the distribution range of abutment pressure.It transfers the stress peak to coal wall and reduces the distribution range. |
