Evaluation of the derivative environment in coal mine safety production systems: Case study in China

摘要

The derivative environment can be separated into five elements: the production condition, job security condition, management regulation, organizational interaction, and culture diffusion. Through field research at three large state-owned coal mining groups in China, all elements of the derivative environment are evaluated in five grey classes from the perspective of reality, expectation, and ideality by using the mixed center-point triangular whitenization weight function method. The results indicate that the derivative environment sends out inferior signals on the whole. From the reality perspective, the production condition is in the "poor" grey class, while the elements of job security condition, management regulation, and organization interaction are in the "pass" grey class. Culture diffusion is located in the "good" grey class. From the expectation perspective, management regulation shows a positive trend, among which the operation pattern, awards and penalty system, and basic safety management system is highlighted the most, while organization interaction shows a negative trend, with caring features prominent therein. From the ideality perspective, there is a deviating phenomenon in key derivative sub elements such as facility level, working time, labor intensity, wages, feedback of basic rights, organizational respect, and communication, which are far beyond an ideal level. The results are of great reference value, improving the level of the derivative environment and promoting the balance between the industrial development and safety control of coal mines.
