Safety evaluation of coal mine internal fire based on the neutral reference value
College of Safety Science and Engineering, Xi’an University of Science and Technology, Xi’an 710054, China
To improve the accuracy of emergency warnings of coal mine internal fire, a new coal mine internal fire safety evaluation method combining AHP with objective, neutral reference was put forward. According to the mechanism of internal fire, an evaluation index system and an evaluation hierarchy model were established, and a percentage scoring rule was set to score the underlying influencing factors. The lower the score, the greater the risk of internal fire. Combining the score of a single item with the weight of a single item, the overall score of coal mine internal fire in different periods was obtained, and the risk degree of coal mine internal fire was quantitatively expressed.
