摘要
应用数据库对老虎台井田其发生的 263 次冲击地压之统计分析表明,岩体动力现象与活动断裂有密切关系。因此,对该井田进行了地质动力区划的研究。通过逐级使用地形测量图并结合其它方法查明了井田Ⅰ～Ⅴ级活动断裂,由各级断裂所分割的断块结构展现出了井田现今构造运动的结果。在确定主应力的基础上,以查明的各级断块结构为模型,应用有限元法进行了区域构造应力场的数值模拟。进而总结了应力分布与岩体动力现象的内在关系。
The paper analyzes the occurrence regularity of rock burst of about 263 times in Laohutai mine field by database, the osculating relations of rock burst and active faults were summarized. Applying geodynamic zoning method, this article has studied the mine field. With topographic map and other methods, some class Ⅰ～Ⅴ active faults that run through Laohutai mine field in modern stress environment are found out by means of geodynamic zoning. The block construction cut by all classes of active faults exposes the result of tectonic movement . Based on determining the principal stress, the paper has made numeric simulation of regional tectonic stress field, and the paper has summed up immanence relation between tectonic stress distributing and dynamic phenomenon of the mine field, by the model built on all class block constructions and the finite element method.
