摘要(Abstract):
讨论了兖州煤田3煤顶板小构造发育特征,重点分析了小断层发育的优选方位;然后分析了应力场作用下形成的4组不同性质的断裂构造,以及它们之间的相互关系;最后概论了不同性质小构造、不同类型组合以及出现在不同位置对煤层顶板稳定性产生的各种不同影响。
The development characteristics of mini-type structures in the roof of No.3 seam in Yanzhou coalfield are discussed,and the emphasis of discussion is about the optimized orientation of minor faults.Then four groups of faults in the action of stress and their correlations are analyzed.Finally a conclusion is summarized: there are different influence on the seam's roof stability because of the different properties,the different combination types and the different positions of mini-type structure.
