Risk evaluation of China’s coal mine production logistics system under coal supply assurance

In order to scientifically and rationally assess the safety condition of coal mine production logistics system, this paper establishes a risk assessment model system based on BWM-Vague set. On basis reviewing large amount literature combining main contributing factors accidents in practice, relatively complete set evaluation index for was established, including 4 primary indexes personnel safety, machine equipment environmental management 16 secondary such as proportion professional technical personnel, fuzzy comprehensive method applied evaluate system. Firstly, BWM assignment is used determine weights each index, after which Vague theory introduced experts are invited score then two combined final evaluation. Finally, empirically tested context enterprise Beijing, with view improving mines.
