摘　　要：综采工作面回采至停采线位置时需要有序回撤综采设备,若采面停采期间顶板出现冒落不仅会影响综采设备正常回撤而且存在一定的安全风险。文中对造成6205综采工作面停采位置顶板冒落原因进行分析,并提出一些针对性预防措施,以期能够为后续大采高综采工作面顶板冒落事故治理以及预防工作开展提供经验借鉴。The fully mechanized mining equipment needs to be withdrawn orderly when the fully mechanized mining face is stoped to the stop line. If the roof falls during stoping, it will not only affect the normal withdrawal of fully mechanized mining equipment, but also have certain safety risks. This paper analyzes the causes of roof caving at the stoping position of 6205 fully mechanized mining face, and puts forward some targeted preventive measures, in order to provide experience for the treatment and prevention of roof caving accident in large mining height fully mechanized mining face.
