Abstract


A large number of research results illustrate the geological structure of coal and gas outburst occurred the different tectonic control role , folds , faults , and other places stress distribution , gas distribution , tectonic coal formation such as the main factors . Distribution of fault structure and a different combination of plane stress fracture by means of numerical simulation study shows that fault structure and fracture area of ??influence of the combination of high - stress areas and high stress gradient distribution in this area roadway construction , there will be a great stress concentration prone coal and gas outburst . This shows that the geological structure of coal and gas outburst control role is rooted in the tectonic stress . In this paper, the geological dynamic division method to identify the active fault Huainan mining area of Mine , mine tectonic stress distribution calculated to determine the mine the B11b seam of high- stress areas and stress gradient area for coal and gas outburst regional prediction and has guidance to take解危measures .
