中文摘要：

以陕西榆林金鸡滩煤矿为工程背景,结合现场原位实测数据,采用FLAC^3D有限差分计算软件对不同厚度软弱岩层下巷道的位移场、塑性区及最大主应力分布特征进行了研究。

英文摘要：

Takes Jinjitan coal mine in Yulin city, Shanxi province as the engineering background. Combining with measured data in situ, numerical software of FLAC^3D was used to simulate the deformation, plastic zone and the maximum principal stress of roadway are influenced by the different thickness of the soft rock.
