分析了许疃煤矿断层的发育特点,总结了研究区矿井构造特征,应用分维法进行了矿井构造复杂程度定量评价,通过井下采样和显微鉴定,划分了研究区构造煤类型,探讨了研究区构造演化,结合构造煤分布范围与发育厚度特征的分析,认为研究区矿井构造复杂程度明显受较大型逆断层的影响,构造煤的发育特征主要受这些逆断层的控制。
This paper analyzes the development characteristics of faults in Xuhuan coal mine, summarizes the structural features of the coal mines in the study area, quantitatively evaluates the complexity of the mine structure by using the fractal dimension method, divides the tectonic coal types in the study area through downhole sampling and microscopic identification, Based on the analysis of the regional tectonic evolution and the analysis of the distribution range and thickness of tectonic coal, it is considered that the structural complexity of the mine structure in the study area is significantly affected by the larger inverse tectonism. The developmental characteristics of tectonic coal are mainly controlled by these reverse faults.
