CHINA MINE ENGINEERING

The present models for evaluating the safety of underground trackless transportation in high altitude mines are less than well rounded. An attempt was made to evaluate the safety thereof in three aspects: the safety/unsafety of humans, transport equipment, and the environment, and a model was built to that effect, with parameters and standards developed for each facet, and weight assigned through the analytic hierarchy process (AHP). The model was further built following the fuzzy comprehensive evaluation (FCE) method to be a multi-factor-coupled man-machine-environment comprehensive safety evaluation model. This model was used in assessing the safety of a certain high altitude mine, and a score of 90.88 was reached, indicating sound safety of the mine.
