| Abstract: | 7-2 coal seam in the south-fifth coal mining area of Daxing Coal Mine is of high gas pressure, complex geological structure, and serious outburst danger. Representative sample of south-fifth 717 mining face is selected to study the tunneling outburst prevention technology, in order to achieve the safe tunneling of 7-2 seam roadway. On the basis of investigation and research, by taking the method combining theoretical analysis, lab tests for samples taken in representative sites and site inspection for predictors, sensitive indicators and their thresholds were initially identified, and the sensitive index thresholds were determined finally after some engineering field-test verification. |
