摘要
本文采用现场观察法和安全检查表法对贵州某无轨开拓地下矿山的地下开采系统、充填站、排矸场、井下爆破器材库、矿区地面交通运输系统和大型无轨设备6个主要作业单元进行了危险源辨识;同时采用作业条件危险性评价法对所有危险源进行了风险评价与分级,指出现有条件下该无轨开拓地下矿山的主要风险是冒顶片帮事故、爆炸事故以及大型无轨设备井下危害;进而采用事故树分析法分析了三类典型事故发生的根本原因,并提出了实现矿山本质安全的风险控制措施和标准化管理方法。
An underground mine in Guizhou currently uses a large trackless mining system.The hazard identification is carried out by the field observation method and safety inspection method for six mining operation units： underground mining system,back-filling station,waste disposal site,explosive and blasting equipment storage,ground transportation and large trackless device.All the hazard sources are analyzed and classified by LEC method.The results show that the existing intolerable risks are mainly manifested in the mining roof accidents,explosion accidents and underground transportation harms related to large trackless device.The main causes of three types of accidents are pointed out by the fault tree analysis,and some efficient risk control measures and the steps to build up a standardized management system to assure the mining safety are proposed.
