摘要
地下矿山在基建生产过程中具有矿建、安装等多项任务.因多种作业之间存在相互交叉生产的特征,从而导致地下矿山基建期安全风险剧增.本文通过对某地下矿山基建期的安全风险进行分析识别,组织矿山全体成员采用LEC法对风险进行评估.评估结果显示某地下矿山基建期较大安全风险主要为火工产品运输、巷道顶板冒顶伤害及透水事故及井下中毒窒息.针对评估的安全风险隐患,从安全组织、风险分级、安全教育培训及专项的安全风险控制四个方面进行管控,从而避免某地下矿山基建期的安全事故发生.
Abstract
Underground mines have multiple tasks in infrastructure production,including mining construction and installation.Due to the characteristic of cross production between multiple tasks,the safety risks during the construction period of under-ground mines have increased significantly.This article analyzes and identifies the safety risks during the construction period of an underground mine,and organizes all members of the mine to evaluate the risks using the LEC method.The evaluation re-sults show that the major safety risks during the infrastructure construction period of a certain underground mine are mainly the transportation of pyrotechnic products,roof caving injuries and permeable accidents in tunnels,and poisoning and suffocation underground.In response to the assessed safety risks and hidden dangers,control measures are taken from four aspects:safety organization,risk classification,safety education and training,and specialized safety risk control,in order to avoid safety acci-dents during the construction period of an underground mine.
