    • Abstract
  • The key of outburst hazard evaluation is to screen out the sensitive index of evaluation region from various evaluation indexes.Taking the evaluation index of outburst hazard in Panxian coal mine of Guizhou Province as research object,the principal component analysis was done by selecting gas pressure p,initial speed of methane emission△P,consistent coefficient of coal f,failure types value,comprehensive index D and K value,and the sensitity of each index was sorted.The result showed that the sensitivity of comprehensive index K value in Panxian coal mine of Guizhou Province is the strongest.
