All tests were conducted in quiet state.Other information including age, length of service for rescue, sex, education, smoking and drinking, and so on were collected at the same time. The mood and influencing factors on psychological quality of the rescue staff were also analyzed.</p><p><b>RESULTS</b>The personality traits of mine rescue staff are close to the national norm.0.6% (2/310) staff showed weak willpower.20.7% (64/310) staff had unstable mood. The E and N factor scores in 20-29 years old group (12.7 ± 4.3 and 12.1 ± 5.1) were higher than 30-39, 40-49, 50-59 years old groups (E factor scores:11.4 ± 3.9, 10.6 ± 3.7 and 10.7 ± 3.9; N factor scores:11.0 ± 5.1, 9.4 ± 4.9 and 6.3 ± 3.4, respectively) (FE = 4.28, FN = 11.35, all P < 0.01) . The L factor score in 40-49 and 50-58 years old groups (13.0 ± 4.2 and 14.8 ± 3.6) were higher than 20-29 and 30-39 years old groups (11.5 ± 3.8 and 12.2 ± 3.8) (F = 6.08, P < 0.01) . Multivariate analysis found that the psychological quality of mine rescue staff was mainly influenced by the length of service (β'E factor = -0.12, β'willpower = -0.12), the amount of participating rescue (β'P factor = 0.12, β'N factor = -0.14), alerting duty (β'L factor = 0.16, β 'error number of target tracking = -0.161) , daily training (β'attention = 0.22,β'total number of aimed at the test = -0.18) and life events (β'N factor = -0.14,β'L factor = 0.13,β'correct number of target tracking = -0.18).</p><p><b>CONCLUSION</b>The mine rescue staff had high level psychological quality, length of service. the amount of participating rescue, and life events in the year effect the psychological quality of mine rescue staff.</p>
