利用数值模拟和相似物理模型方法,讨论了工作面推进过程中围岩应力转移变化规律,得到了压力演化规律和特征.结果表明,工作面开挖后,伴随着应力不断转移和调整,将在采场围岩中形成长轴在采煤工作面走向,短轴在工作面倾向的近似鸡蛋形厚壁压力拱;随着工作面推进距离的加大,压力拱拱体的内边界外移,拱体变厚,拱内围岩应力增加区. By using numerical simulation and similar physical model methods, the variation regularity of stress transfer of surrounding rock in the process of working face advancing was discussed, and the pressure evolution law and characteristics were obtained.The results show that with the continual transfer and adjustment of stress, In the surrounding rock of the stope, an approximate egg-shaped thick-walled pressure arch with the long axis running along the coalface and the short axis inclined at the working face is formed. As the working distance increases, the inner boundary of the pressure arch body moves outward, Arch thickening, arch surrounding rock stress increases the area.
