摘　　要：为了研究大埋深两硬工作面的应力特征,采用FLAC3D数值模拟软件,研究了大埋深厚硬顶板条件下坚硬煤层中超前支承压力和塑性区的分布规律。通过对塑性区的分析可知该区域附近并不能产生足够的塑性卸压变形需及时采取卸压措施。In order to study the stress characteristics of great overburden dual hard working face. The distribution characters of lead abutment pressure and plastic zone of dual hard deep working face with FLAC3 Dwere analysed. Though the distribution characters of plastic zone was analysed,could know the area around do not emerge enough plastic deformation to release the pressure and should to take some measures to release the pressure.
