Abstract:

By constructing a conceptual model of safety system to enhance people's understanding of it, the actual needs of figurative gas extraction standard assessment were analyzed. The elements and structure of gas extraction standard assessment model were summarized, and the single-hazard safety evaluation model and the multi-hazard coupling safety evaluation model were abstracted. These were then generalized to form ″binary structure and ternary system safety model″ (referred to as the binary-ternary model), which holds universal significance. The deductive process of the binary-ternary model was analyzed, and the axioms of the safety system based on this model, including the system axioms, prediction axioms and reflection axioms, were put forward. The results show that two-three model and the security system axioms based on the two-three model clearly define the triadic composition of safety system, clarify the mechanism of the role of each element, reveal the characteristics of the relevant laws, and provide a path for model transformation.

Key words: work safety, safety evaluation, binary-ternary model, safety system, axiom, gas extraction standard assessment
