摘　　要：为了明确开平向斜深部瓦斯赋存的地质控因,从瓦斯的生成和赋存条件出发,系统研究了地质构造及其演化、煤层埋深及厚度和顶板岩性对开平向斜两翼矿井瓦斯的赋存影响。研究表明,在开平向斜不同构造部位,含煤地层埋藏次数不同。在瓦斯赋存方面,地质构造使得向斜两翼瓦斯含量具有明显的差异性,煤层埋深与瓦斯含量具有较好的相关性,而煤层顶板岩性和煤厚均在一定程度上影响着瓦斯的赋存。In order to clarify the geological control of the deep gas distribution in the Kaiping slope,systematically studied the influence of geological structure and its evolution,the depth and thickness of coal seams and the lithology of the roof on the gas distribution in the two wings of the mine in the Kaiping slope from the conditions of gas generation and distribution.The study shows that the number of coal-bearing strata buried varies in different tectonic parts of Kaiping slope.The geological structure makes the gas content of the two wings of the slope obviously different,and the depth of coal seam burial has a good correlation with the gas content,while the lithology of the coal seam roof and the thickness of the coal both affect the gas content to some extent.
