ISO 19434:2017根据事故的来源或原因、事故类型及其结果或后果对矿山事故进行了分类。后者只包括对人造成后果的事故，而不包括设备或机械。 简要定义了矿山事故的原因、类型和后果的不同类别，并为每个类别分配了一个3位代码。这些可以结合起来，最终为每种类型的矿难分配一个唯一的15位代码。然后，该代码可以用于统计分析。同样，分配的代码清楚地显示了矿山事故所属的原因类别、事故类型和后果。 ISO 19434:2017适用于所有地表和地下矿山。 注:除ISO 19434:2017中给出的项目外，事故可根据其他项目进行分类，尤其是在研究和其他分类方案中。这些可以是，例如，基于财务损失水平的分类；人员的性别、年龄、专业技能、服务条款和学历；事故发生的周、月、年、小时；场地面积等。虽然这些分类有助于健康和安全主管做出某些决定，但ISO 19434:2017并未考虑这些分类。

ISO 19434:2017 establishes a classification of mine accidents by their origin or causes, by the type of accident, and by their results or consequences. The latter includes only the accidents resulting into consequences on people, not equipment or machinery. Different categories of causes, types and consequences of mine accidents are briefly defined, and a 3-digit code is assigned to each category. These can be combined to ultimately allocate a unique 15-digit code to each type of mine accident. This code can then be used in statistical analysis. Similarly, an allocated code clearly shows to which categories of causes, type of accident and resulting consequences the mine accident belongs to. ISO 19434:2017 is applicable to all surface and underground mines. NOTE: Accidents can be classified in terms of other items than those given in ISO 19434:2017, especially in researches and in other classification schemes. These can be, e.g. classifications based on the level of financial damages; gender, age, professional skills, terms of service and academic degree of the personnel; days of week, month, year, hour of accident; area of site, etc. While these classifications can be useful to enable certain decisions to be taken by the health and safety executives, they are not considered in ISO 19434:2017.
