YANG Yu-zhong1,2,ZHANG Qiang1 (1.School of Management and Economics,Beijing Institute of Technology,Beijing 100081,China;2.School of Energy Science and Engineering,Henan Polytechnic University,Jiaozuo,Henan 454010,China)  
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.
