New Coupling Model for Risk Assessment of Spontaneous Fire in Coal Mine

More Information
  • Published Date: July 19, 2018
  • The spontaneous fire in coal mine affects the safe and efficient production of coal mine.At present, the evaluation accuracy of spontaneous fire in coal mine is low, and the evaluation method is too old.To solve these problems, we propose a kind of risk evaluation coupling model for spontaneous fire based on set pair analysis and interval triangular fuzzy number, the multivariate connection number of set pair analysis can take account of the deterministic and random in the evaluation of spontaneous fire in coal mine; the interval triangular fuzzy number can describe the continuous change process of the difference coefficient of connection number in identical discrepancy structure. By using the coupling model and fuzzy comprehensive evaluation method, we evaluate the spontaneous fire hazard in Hegang Coal Mine. The evaluation results are consistent with the actual results, moreover, the connection number can also directly reflect the strength and weakness of spontaneous fire in coal mine.
