为分析断层及褶曲地质构造对煤层瓦斯的控制作用,利用断裂分维值、煤层底板埋深构造曲率值量化了地质构造复杂程度。以卧龙湖矿8煤层为例,通过分析2者与煤层瓦斯含量的关系,得出断裂分维值大的地方构造相对复杂,在断裂构造复杂带附近瓦斯含量小,而对于断裂构造复杂程度次一级复杂带内瓦斯富集,且小于此区域内瓦斯含量与断裂分维值成正相关性;同时得出煤层底板埋深构造曲率值与煤层瓦斯含量存在较好的正相关性。
In order to analyze the control effect of fault and fold geological structure on coal seam gas, the fractal dimension of fractures and the curvature of the floor depth of coal seam are used to quantify the complexity of geological structure. Taking the No.8 coal seam of Wolong Lake as an example, by analyzing the relationship between the two and the coal seam gas content, it is concluded that the fractures with large fractal dimension value are relatively complicated, with low gas content near the fault zone. However, A complex complex with gas accumulation in the inner zone and less than the gas content in this area has a positive correlation with fracture fractal dimension. At the same time, it is concluded that there is a good positive correlation between the construction curvature of the coal floor and the coal seam gas content.
