Abstract：The article proposes a systematic comprehensive evaluation index system based on evaluation of various disasters and the hazards that may be caused by the closure of open-pit mines.This system covers multiple aspects such as geological environment,hydrological conditions,soil quality,vegetation coverage and air quality.Based on the indicator system,we develop a new multi-level fuzzy comprehensive evaluation model.This model uses CRITIC weighting method to automatically quantify the importance of each indicator by calculating the relative conflict degree and contrast strength between each indicator.The results show that this model can accurately identify and evaluate the main disaster risks after the closure pit,confirming the effectiveness of the multi-level fuzzy comprehensive evaluation model in disaster assessment.The detailed disaster response strategies provide effective operational guidance for the management work after the closure pit,ensuring a smooth transition of closure activities and sustainable socio-economic development.
