The Main Factor Controlling the Coal and Gas Outbursts in the Eastern Pingdingshan Mining Area
By analyzing the gas occurrence, it is found that ground stress plays a leading role in coal and gas outburst in eastern coal mines of Nos. 8, 10 and 12 in Pingdingshan Mining Area where show the most serious outburst hazards.

| description | By analyzing the gas occurrence, it is found that ground stress plays a leading role in coal and gas outburst in eastern coal mines of Nos. 8, 10 and 12 in Pingdingshan Mining Area where show the most serious outburst hazards. According to the isograms of coal seam depth in F Group, the relationship between the distributions of the fold tectonic stress and the coal and gas outburst was simulated using the ANSYS program. The result shows that the stress concentrates near to the fault and the outcrop of the fault enhances the possibility of gas outburst. The shear stress in the north of the anticline is greater than that in the south. The shear stress direction on the north wing of the anticline is dextral and the coal seam in this area exhibits highest possibility for gas outburst. However, on the surrounding rock, the shear stress direction on the north wing of the anticline is sinistral. The regions with fold tectonic stress ranging from 1.44 to 4.47 MPa correspond to the sites with high risk of gas outburst. Ground stress is the main factor controlling the coal and gas outburst in the three mines. Currently, the distribution of coal and gas outburst in the three mines is in agreement with that of coal shear stress. |
