Performance evaluation of coal mine safety production standardization based on contribution rate method

In order to strengthen the construction of safety production standardization in coal mine, the standardized performance indicators of safety production in coal mine were studied through literature research and standard analysis. The basic indicators were optimized combined with KPI theory, and the performance evaluation system of safety production standardization was constructed. With the combination of improved AHP and fuzzy comprehensive evaluation method, the contribution coefficient was introduced, and the calculation model of contribution rate of safety production standardization was constructed and applied in practice. The results show that the introduction of contribution rate can reasonably quantify the standardization performance in coal mine safety production. From 2019 to 2021, the contribution rates of safety production standardization to the safety performance in coal mine enterprise A are 16.52%, 22.13% and 27.81%, respectively, showing an increasing trend year by year. It has a significant positive impact on enterprise safety management (0.344), safety facilities (0.273), safety environment (0.228) and so on. The study helps to further strengthen the construction of safety production standardization in coal mine, and provides a theoretical basis for promoting the active implementation of safety production standardization in coal mine.
