Application of in-situ Stress Measurement on Coal and Gas Outburst Regional Prediction
For the reduction and prevention of coal and gas outburst in the sixth mine of Hebi, in-situ stress measurement and mechanical parameters were conducted, and structural pattern and the features of main faults were studied by geo-dynamic division. Stress field was simulated and distribution of stress field was obtained in the coal seam. Also with the analysis of the influence factors such as gas pressure, gas content, coal Protodyakonov coefficient and structure coal by solid-flow coupled analysis, spot measurement and drilling data fitting, the internal relation between the factors and the hazard of coal and gas outburst has been ascertained through multi-factor pattern recognition method. On the basis of contrastive analysis the pattern of coal and gas outburst between prediction region and mined region, the hazard of every predication unit has been determined. The mining area was then divided into respective area according to the hazard of every predication unit.
