استراتژی بهینه سازی استفاده از قابلیت مدیریت ایمنی معدن ذغال سنگ - یک مطالعه موردی از 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.

According to official data of State Administration of Work Safety, the death toll of coal mine accident accounts for 30.67% of that in mining and commercial enterprises from 2004 to 2010, which leads to heavy losses of human life and property, destroys image of country. According to statistical data of major accidents case of 49 coal mine in recent 5 years, “operation against rules” and “command against rules” account for 61.9% of the accident reasons, and “low safety management capability” accounts for 38.1% of it. It is shown that psychological factors of coal miner will contribute to safety situation of coal mine positively (Burt et al., 2009 and Chen et al., 2009). On the contrary, the worse attitude toward errors and risking behaviors is, the lower “job satisfaction” and risk preference behaviors are, which may lead to more coal mine accidents (Margolis, 2010 and Hohnen and Hasle, 2011). Since subjective factors of coal miner contribute to the accident of coal mine seriously, it should be paid more attention to. Safety management capability of coal mine (SMCCM) has close relationship with employee’s attitude as a kind of cumulative safety knowledge (Liu and Li, 2008). The bounded rationality of coal miner makes it difficulty to pursue optimal solution of SMCCM, so utility of coal miners should be discussed to discover optimization strategy of it.

Then the utility optimization strategy of SMCCM is summarized as follows: First, “rule safety knowledge” should be strengthened above all, because it is absent at present. Coal miner’s participation in the implement of laws and regulations should be increased, and the fine tradition of coal mine should be carried onto enhance employee’s sense of identity towards coal mine. In addition, the management method of coal mine should be refined. Second, “job satisfaction” should be paid more attention to. Working analysis of the special position, especially aiming to female employee and employee with high education level; and then training and guiding should be done on schedule to enhance their work adaptation. The dilettante employee should be cared and given more guidance to help them pass through their mental fatigue. Third, employee benefit should be concerned carefully to prevent its negative effect. Development of coal mine and coal miner should be cared at the same time. The combination of the promotion, material incentives and spiritual motivation should be applied to increase coal miner’s satisfaction. Kinds of measures should be taken to improve the management effectiveness of coal mine. The positive demonstration effect of CPC member and CCYL member should not be neglected.
