Area of Science:

• Mining Engineering
• Safety Science
• Systems Engineering

Background:

• Existing safety system evaluation theories require enrichment.
• Comprehensive evaluation of back-filling control systems is crucial for operational safety.

Purpose of the Study:

• To develop a multi-level comprehensive safety evaluation index system for back-filling control systems.
• To construct a set pair matter-element extension comprehensive evaluation model.

Main Methods:

• Developed a 16-factor index system across four aspects: slurry preparation, pipeline monitoring, strength monitoring, and visual management.
• Employed order relationship, entropy weight, and Lagrange combination weighting methods for indicator weighting.
• Utilized set pair matter-element extension principles to construct membership functions and calculate connection degrees.

Main Results:

• The proposed model achieved consistent and accurate safety evaluations across three case studies.
• Evaluation results were validated against cloud model and attribute recognition models, showing strong agreement.
• The model effectively assesses the safety level of back-filling control systems.

Conclusions:

• The developed comprehensive evaluation model is applicable and effective for back-filling control systems.
• Combination weighting methods and set-pair extension matter-element theory provide a robust framework for safety assessment.
• The study contributes to advancing safety system evaluation theory in mining operations.
