Utility optimization strategy of safety management capability of coal mine – A case study of JCIA

This article describes optimization strategy of SMCCM from perspective of utility of coal miner with the method of empirical research. Four elements of SMCCM are put forward which consist of “employee safety knowledge”, “equipment safety knowledge”, “environment safety knowledge” and “rule safety knowledge”. Eight elements of utility are put forward which consist of “benefit satisfaction”, “promotion satisfaction”, “job satisfaction”, “enterprise satisfaction”, “management satisfaction”, “colleague satisfaction”, “relationship satisfaction” and “communication satisfaction”. Then hypotheses of influence path between SMCCM and utility are proposed. JCIA is chosen as the sample to carry out survey, which questionnaire is designed based on the likert six-point scale to avoid the middle tendency of the test samples. Data analysis is done from following angles: analysis of the structure and utility of test samples, variables analysis of SMCCM and utility, model analysis of interaction between SMCCM and utility. And then results are obtained from the analysis of elements of SMCCM and elements of utility. Conclusions: first, “rule safety knowledge” should be strengthened above all; second, “job satisfaction” should be paid more attention to; third, coal miner’s benefit should be concerned specially.

► We discuss optimization strategy of SMCCM from viewpoint of utility. ► We build the relationship between elements of SMCCM and utility. ► Rule safety knowledge should be strengthened above all. ► Job satisfaction should be emphasized, especially to dilettante employee. ► Coal miner’s benefit should be cared specially to prevent it’s negative effect.
