摘　　要：在地下矿山建设和生产时期,水患从始至终都是影响正常生产及人员安全的重要因素。为有效评价地下磷矿矿山开采作业中遇到水患风险情况,基于地下磷矿矿山掘进作业活动、工作步骤和场所部位,选取透水作为主要事故类型,并对涉及水患的作业岗位进行识别判定,运用增加修正系数后的作业条件危险性分析法对其进行评价,得出了相对前一个风险评价时期的风险等级,以及涉及水患岗位面临透水事故三个重要参数-事故发生的可能性变化、暴露于危险环境频繁程度和危险性相较于前期变化,然后确定使得风险的等级变化的影响要素,使得各个责任部门、岗位以及管控层级明确自身防控重点,落实安全责任。During the construction and production period of underground mine,flood is an important factor affecting normal production and personnel safety from beginning to end.In order to effectively evaluate the risk of flooding encountered in underground phosphate rock mining operations,based on the excavation activities,working steps and sites of underground phosphate mines,select water permeability as the main accident type,and identify the positions involved in water,using the risk analysis of operating conditions after increasing the correction coefficient.Obtain risk levels relative to the previous risk assessment period,and the three important parameters of the flooding accident-the possible change of the accident,the frequency of exposure to the dangerous environment and the risk compared to the previous change.Then determine the impact elements that change the level of risk,make each responsible department,posts and control levels to clarify their own prevention and control priorities,implement safety responsibility.
