Comprehensive Evaluation Model of Coal Safety Risk based on Entropy Weight Theory

Abstract

Coal is an important basic energy in China, and has an important strategic position in the national economy. Under the guidance of system theory, together with the comprehensive using of the principle and method of system engineering, this paper systematically analyzes the structural characteristics, influence factors, mechanism of the safety risk system of coal enterprise. At the same time, this paper establishes a comprehensive evaluation index system of coal mine safety and risk, and constructs comprehensive evaluation model of coal mine risk based on safety and risk index, as well as comprehensive evaluation model of coal mine safety based on entropy weight method and grey relational analysis; Besides, the practical research has performed on four coal mines in Su county Mine Area, Huabei Mining Group. The research results are of great theoretical and practical significance for the scientific countermeasures to improve the safety production of coal enterprises and to promote the fundamental improvement of the coal industry safety production situation.
