中文摘要：
应用可拓学的理论与方法，结合熵理论，建立了基于熵权的可拓综合评价模型．该模型以综合关联度作为评价准则，避免了评价中的主观性．使用该方法对平顶山煤业（集团）有限责任公司一矿运输系统进行安全性评价，得出了各子系统安全性优劣的排序及安全性差异程度，同时指出了在人、机、环境等方面各子系统存在的安全问题，并提出了相应的改进对策．
英文摘要：
A model of extensible synthetic evaluation based on entropy weight is established, applying the theory and methods of extenion and entropy theory. The comprehensive correlative degree is taken as the rule of evaluation. As a result, the subjectivity in evaluation can be avoided. The method has been applied in the safety evaluation of colliery transportation in mine No. 1 of the Ping Dingshan Coal Group Corporation Ltd, The order and differences of safety of underground transportation subsystems were attained. At the same time, problems of safety existing in man, machine and environment in coal mine transportation systems were pointed out. Corresponding countermeasures to improve safety of colliery transportation are put forward.
