摘　　要：描述了两起典型的煤巷冒顶事故实例,结合两起事故所采取的具体支护方式,通过对事故现场观察机理分析以及冒顶抽象力学模型的分析,得出了事故发生的原因所在,给出了事故的分析结论,提出了一些防治措施。The examples of the two typical coal laneways roof fall accidents were described in this paper. Then according to the instance and the material support manners of the roof fall accidents, the locale observation mechanism and roof fall abstract mechanics models were analyzed. The true causations of the accidents are gained, and the analyzed conclusion of the accidents is also given. the prevention countermeasures to the coal laneways roof fall accidents are enumerated in the paper.
