根据地质观测和分析和对若干断层上的定向标本的显微构造研究及岩组分析，作者认为测区──福建安溪东阳煤矿的构造格式不是以往地质文献中提出的单斜构造，而是在由东西向宽缓褶皱带组成的构造基础上迭置了较紧闭的北西向褶皱带。这一构造格式还被应变模拟实验所再现。 文章最后对上述北西向迭置褶皱带的成生机制进行了粗略的探讨。 According to the geological observation and analysis and the microstructure study and the analysis of the rock mass on a number of directional samples, the authors believe that the structure of the survey area - that is, the Dongyang coal mine in Anxi, Fujian Province is not the monocline structure proposed in the geological literature in the past, By the east-west relief belt composed of the composition of the structure of the more tightly stacked Northwest fold belt. This construction format was also replicated by contingency simulation experiments. Finally, the paper makes a rough discussion on the mechanism of the above-mentioned northwest fold fold belt.
