摘要
应用地质动力区划方法,通过逐级使用地形测量图,并结合其它方法查明了大兴井田的Ⅲ-Ⅴ级活动断裂,由此展现了井田的现今构造运动结果。以实测地应力为基础,按查明的各级断块结构建立模型,应用有限元法进行了区域构造应力场的数值模拟。进而分析了该井田煤与瓦斯突出的原因,并对其煤与瓦斯突出作出了区域预测。
Some class Ⅲ-Ⅴ active faults that run through Daxing mine field are found out by means of geodynamic zoning, with topographic map and other methods. Thereout the result of tectonic movement is exposes. Based on surveying the principal stress in the mine, numeric simulation of regional tectonic stress field hes been made by the model built on all class block construction and the finite element method. Then in allusion to the mine field, the paper has analyzed the causations of coal and gas bursts, and has worked out district estimate about coal and gas bursts .
