Controlling Effect of Tectonic Stress Field to Coal and Gas Outburst

摘要：

To study the regional controlling effect of tectonic stress field to coal and gas outburst in Pingdingshan 8th mine J15 coal seam in the northeast of Thrust belt in the south of North China coal area, this paper bases on geodynamic division methos, and makes a numerical simulation of rock stress field in this coal seam roof. A stress contour map is draw to show the changing situation of rock stress, and this map divides tectonic stress areas of the coal seam roof into three areas. Conclude that tectonic stress areas control the areas of coal and gas outburst, and the distribution of tectonic stress decides regional distribution of coal and gas outburst. It provides one example of controlling effect of tectonic stress field to coal and gas outburst, and offers a judgement of prediction and prevention of coal and gas outburst during mining.
