Research on Definition and Risk Assessment of Near Miss Events in Coal Mine

At present, extraordinarily serious casualties in coal mine is often pay more attention, however, a large number of minor accidents, especially these events caused no casualties or economic loss is not seriously enough attention. Which lead to neglect or even let near miss and the presence of attempted events. In this study, the near miss of mines was definite, and its difference and relationship with hazards and risks was analyzed. Drawing on traditional LEC risk assessment methods, relative risk assessment model of near miss was constructed by using f risk index, practice has proved that the classification results are basically the same with the traditional LEC risk assessment methods, and it can reflect the risk characteristics of near miss events from the many perspectives. Which has great practical significance in eliminating all kinds of production safety hazards in coal mine, preventing the occurrence of major accidents in practical work.
