为研究平顶山矿区东西分区的特征,对比多种因素,分析矿区东西区的瓦斯分布特征、突出分布特征和构造煤分布规律,论述地应力和瓦斯耦合对东部矿区突出的控制作用。结果表明,东区瓦斯含量和突出强度明显高于西区,原因是其受控于东区褶皱区,地应力和瓦斯耦合控制着东区的突出;而锅底山断层的形成及其后期演化使西区突出危险性小于东区。东西地质构造的不同,不但导致构造煤、瓦斯含量分布不同,而且给地应力与瓦斯耦合提供了不同的条件。总之,东部褶皱区是造成东区与西区产生明显分区性差异的关键影响因素。
In order to study the characteristics of east-west division in Pingdingshan mining area and compare various factors, the paper analyzes the distribution characteristics of gas in the east and west areas of the mining area, highlights the distribution characteristics and tectonic distribution of tectonic coal, and discusses the outstanding control effects of geostress and gas coupling on the eastern mining area. The results show that the gas content and salient intensity in the eastern area are obviously higher than those in the western area because they are controlled by the fold area in the eastern area. The stress and gas coupling control the prominence of the eastern area. The formation and subsequent evolution of the pan-bottom mountain faults make the western area a prominent danger Sex is less than the East. The difference of geologic structure between east and west not only leads to tectonic coal but also different distribution of gas content, and provides different conditions for the coupling of geostress and gas. In conclusion, the eastern fold zone is the key factor that causes significant regional differences between the eastern and western regions.
