Evaluation and Analysis of Influencing Factors of Safety Risks in Blasting Operations Based on Entropy Weight and TOPSIS Model

为科学评价爆破作业安全风险影响因素，文章建立了基于熵权和TOPSIS方法相结合的爆破作业安全风险评价模型。该模型以“三实”作业法律法规为基础，运用熵权法精准确定了影响因素的指标权重，并利用TOPSIS法对爆破作业的影响因素，如安全管理、人员、环境、设备等，进行分级评价，得出影响因素的最优排序结果，从而设计出爆破作业的最合理方案。最后通过实践验证了本方法的可行性，其结果表明该模型方法可靠有效，且有效避免了主观性。To scientifically evaluate the factors affecting the safety risks of blasting operations, this paper establishes a blasting operation safety risk assessment model based on the combination of entropy weight and the TOPSIS method. This model is based on the laws and regulations of the “Three Realms” operation and uses the entropy weight method to accurately determine the index weights of influencing factors. The TOPSIS method is used to grade and evaluate the influencing factors of blasting operations, such as safety management, personnel, environment, equipment, etc. The optimal ranking of influencing factors is obtained, and the most reasonable blasting operation plan is designed. Finally, the feasibility of this method is verified through practice, and the results show that the model method is reliable and effective and effectively avoids subjectivity.
