Description
Summary:Coal spontaneous combustion is one of the major threats to coal production in China. It is very important to quote scientific and effective evaluation in order to prevent coal spontaneous combustion effectively. This paper use catastrophe theory to study the risk assessment method of coal spontaneous combustion. Used analytic hierarchy process (AHP) to determine the weight of 16 indicators to establish an evaluation model which based on catastrophe theory. Analyzed the catastrophe level value of coal spontaneous combustion hazard obtained by the catastrophe theory calculation method to determine the hazard level,and put forward corresponding suggestions. Through engineering case studies, the feasibility and effectiveness of the coal spontaneous combustion risk assessment method proposed in this paper is verified.
