地表水进入井下发生淹井事故是矿井水灾的一种类型,危害很大。所有井工矿,都程度不同的存在水灾的威胁。生产中,防排水措施不当,容易造成淹井事故。因此,把地表水存在的淹井可能列入危险源进行辨识并加以控制,具有重要的现实意义。地表水淹井危险的辨识危险源辨识必须采取系统性原则来进行,地表水淹井危险的辨识可依据事故树分析法来进行,可使危险源的辨识过程和分析思路更为直观、清晰和全面。用它描述事故的因果关系直观、明 It is a type of mine flood that the surface water is flooded in the well, which is very harmful. All boreholes and mines, to varying degrees, are threatened by floods. In production, improper anti-drainage measures are likely to cause flooding accidents. Therefore, it is of great practical significance to identify and control flooded wells where surface water exists. Identification of danger of surface water flooding Hazard identification must take the principle of systematization. The identification of danger of surface water flooding can be carried out according to the method of fault tree analysis, which can make the process of identification and analysis of hazard identification more intuitive and clear. comprehensive. Use it to describe the causal relationship between accidents visually
