Evaluation on Safety Investments of Mining Occupational Health and Safety Management System Based on Grey Relational Analysis

Jiangdong Bao, Jan Johansson, and Jingdong Zhang
Abstract—In order to effectively evaluate the relationship between safety investments and accident impact losses in the mining occupational health and safety management system, a grey relational analysis model is established. Firstly, 4 firstgrade indicators including safety technical measures fee etc. and 23 second- grade ones including ventilation system etc. are established. Secondly, by calculating the grey relational analysis between the variables of the data sequence and the system characteristic variables, analysis results of advantages and the evaluation ones are obtained. Finally, the model is validated by case study. The results demonstrate that the investments of safety technical measures and safety management and training have a great impact on the accident losses. The quantitative analysis of safety investments and losses is realized by the model, which provides the direction for the enterprise's strategic investments and reduces the economic losses.

Index Terms—Mining, OHSAS18001, safety investments, accident losses, grey relational analysis.
