| 摘 要： | 针对北京长沟峪煤矿东二西四槽回采巷道的地质条件，利用FLAC^2D软件模拟研究了该巷道的非对称变形特征及强度薄弱部位，确定了用于这类巷道的合理的锚网索支护方案，通过现场实施，进行了巷道表面位移、围岩深部位移、锚杆（索）动态锚固力等内容的矿压监测。数据显示，该支护方案设计合理，取得了理想的支护效果及显著的经济效益，对类似急倾斜煤层支护提供了有益借鉴。

| Abstract: | In view of geological conditions of mining roadway in 4# coal seam Beijing Changgouyu Mine,FLAC^2D is used to sinmlate and research the characteristics of non-symmetric deformation and weak parts of strength. The reasonable anchor Support program is identified for the roadway. By means of site implementation and monitoring displacement of roadway surface, deep displacement of surrounding rock and dynamic anchor force of bolt （cable） ,the program is found to be reasonable. Ideal support effect and significant economic benefits have been achieved. Useful references for support of similar steep seam is provided. |
