Research On Hazard Identification And Safety Measures Of AnJialing Open-pit Mine Goaf

Hazard identification is the important indicators in coal mine safety production, This paper based on BP neural network model to analyze the stability of Anjialing open-pit mine goaf. Set up AnJialing open-pit mine hazard identification model which is based on analytic hierarchy process (AHP), study the hazards index weights, determine the main hazards of Anjialing open-pit mine goaf is the coal spontaneous combustion, the goaf water, poisonous and harmful gases and the thickness of the overburden.Through the analysis and research of Anjialing open-pit mine goaf safety mining major hazards.The mined-out area is divided into the following several types, high temperature flame goaf, ponding goaf, poisonous gas of mined-out area, the not real goaf, according to different goaf, put forward different safety mining measures, mainly study the relationships between gob span and goaf safety roof thickness, finally put forward the Anjialing open-pit mine goaf equipment configuration scheme.
