| 摘 要： | 为了研究华北聚煤区南缘逆冲推覆构造带东北缘的区域构造应力场对平顶山矿区八矿己15煤层煤与瓦斯突出的控制作用,基于地质动力区划方法,对己15煤层顶板的岩体应力状态进行数值模拟,以应力等值线图的形式展示岩体应力的变化情况,将己15煤层顶板构造应力进行构造应力区的三级划分.分析得出构造应力场对煤与瓦斯突出起控制作用,构造应力区的分布决定了煤与瓦斯突出的区域性分布,为研究构造应力场对煤与瓦斯突出的控制作用提供了例证,为矿井开采过程中煤与瓦斯突出的预测和防治提供了依据.

| Abstract: | To study the regional controlling effect of tectonic stress field on coal and gas outburst of PingDingshan eight mine mining area in the northeast of Thrust belt in the south of North China coal area,this paper bases on geodynamic division method,and makes a numerical simulation of rock stress field in this seam.A stress contour map is drawn to show the varying situation of rock stress,and this map divides tectonic stress area of the roof into three areas.Concludes that tectonic stress areas control the are... |
