摘　　要：为了解决霍州煤电集团公司庞庞塔矿的9-700综放工作面在开采特厚煤层时面临的沿空巷道大规模变形的问题,采用现场实测、理论分析、现场试验的方法,研究了厚煤层综放工作面沿空巷道冲击地压与大变形协调控制机理,得知沿空巷道大规模变形由于顶板的二次侧向破断所引起,并提出了综合治理方案,在该工作面进行实际应用,得到了较好的效果。为以后类似工作面开采提供借鉴。In order to solve the huo zhou coal mine group company PangPang tower 9-700 fully-mechanized caving face in mining thick coal seam roadway along large deformation problems,using the field measurement and theoretical analysis,field test method,studied the thick coal seam fully-mechanized caving roadway along the impact ground pressure and large deformation coordination control mechanism,that along the empty mass of roadway deformation caused by secondary lateral roof breakage,and put forward the comprehensive control scheme,in the face of practical application,obtained the good effect.It provides reference for similar working face mining in the future.
