安家岭露天矿过采空区危险源辨识及安全措施研究

Hazard identification and safety measures in Anjialing Open-pit Mine goaf

危险源辨识对提高煤矿安全生产具有重要的现实意义。研究建立了基于层次分析法的安家岭露天矿危险源辨识模型,确定了危险源指标的权重。依据危险源辨识的权重研究了安家岭露天矿过采空区安全开采存在的主要危险源,并把采空区分为高温明火采空区、积水采空区、存在有毒气体的采空区、未冒实采空区,针对不同的类别的采空区提出了相应的安全开采措施。

Hazard identification has a far reaching significance for coal safety production. The author establishes hazard identification model based on AHP method in Anjialing Open-pit Mine, and determines the weight of hazard index. According to the weight of hazard identification, the article researches the existing major hazard of safe mining and divides goaf into high-temperature open fire zone, water accumulating zone, toxic gases zone, no subsidence zone. Aiming at different type goaf, the article presents the corresponding safe mining measures.
