摘　　要：针对山西晋城某矿大断面切巷地质力学特征,提出了锚梁网索联合支护的方案,并采用矿压监测对开切眼的支护效果进行了分析。结果表明,切巷采用联合支护技术是合理的,所采用的支护参数能有效控制围岩变形。For the geological mechanics characteristics of large cross section open-off cut in a mine of Jincheng, the plan of combined support of anchor beam and wire rope is put forward, support effect of open-off cut is analyzed by using mine pressure monitoring. The results show that open-off cut is reasonable by using combined support technology, the used supporting parameters can effectively control the deformation of the surrounding rock
