【摘要】 对于井下民采空区处理,采用事故树分析法(FTA)进行综合安全评价,采用作业条件危险性评价法(LEC)评价人们在空区处理施工作业这种具有潜在危险环境中作业的危险性。据此分析了空区处理中引起施工过程自身伤害、爆破震动灾害、地表设施损害、地压引起灾害四个方面的主要危险因素。最后,依据上述评价结果,提出相应的防范对策和技术保障措施,以保障施工安全。更多还原

【Abstract】 For treatment of non-regular mined-out area underground,the Fault Tree Analysis(FrA)is used for comprehensive safety evaluation,and the LEC is used to assess the risk in working at treatment of mined-out area with a potentially dangerous environment.From this,four main danger factors in treating the mined-out area are analyzed from injury of themselves,damage of blasting and vibration,damage of ground surface construction,to scourges caused by ground pressure. Lastly,in view of above evaluation,some related counter-measures and technical safeguards are put forware to ensure the safe construction.更多还原
