Assessment and prediction of environmental safety risk at the site of emergency rescue for underground space collapse
To ensure the safety of emergency rescue operations and the normal functioning of equipment in un-derground space collapse incidents,and to enhance the safety assurance capabilities of emergency rescue opera-tions,it is pivotal to first establish an environmental safety risk assessment indicator system for underground space collapse emergency rescue scenes.By integrating the analytic hierarchy process(AHP)and the technique for order preference by similarity to an ideal solution(TOPSIS)method,the safety status of the on-site environ-ment can be evaluated.Subsequently,combining the autoregressive moving average(ARMA)and exponential smoothing models,the future safety status of the site environment within a certain period can be forecasted.Ul-timately,the assessment and prediction models are applied to a rescue case in a coal mine drilling site,with recommendations and improvements proposed for the rescue operation.The research results can provide data and a decision-making basis for the safety protection system and the configuration of ventilation facilities on the emergency rescue sites of underground spaces.
