Sensitivity Analysis of Effect Inspection Index for Working Face Outburst Prevention

this paper introduces the "three rates" analysis method of inspecting index sensitivity in effectiveness of outburst prevention.According to test data of outburst prevention in Rongguang coal mine 1501 working face 81 group,the method of "three rates" have been used to analyze the index sensitivity of effect inspection in C₅ coal seam.The coal cuttings gas desorption index △h₂ is determined the most sensitive indicators of effect inspection in outburst prevention of C₅ coal seam.
