通过研究平顶山矿区17对生产矿井的瓦斯地质特征，分析各矿井瓦斯含量、瓦斯压力和涌出量实测数据，总结了平顶山矿区瓦斯赋存分布规律。运用瓦斯赋存构造逐级控制理论厘清了区域构造演化、矿区和矿井构造对平顶山矿区瓦斯赋存分布的控制，提出了平顶山矿区瓦斯赋存的构造逐级控制特征：区域板块构造运动及演化奠定了平顶山矿区高瓦斯的基调；矿区构造李口向斜确定了矿区瓦斯东高西低、呈轴对称分布的总体规律；矿井构造主导矿井各煤层瓦斯赋存和矿井区域瓦斯赋存的差异性。研究成果为准确预测瓦斯赋存分布和预防煤与瓦斯突出提供了依据。

Based on the research on gas geological characteristics of 17 pairs of outburst mines, we analyzed the measured data of gas content, pressure and emission quantity, summarized the rules of gas geology in Pingdingshan mining area. It has clarified the control of the regional tectonic evolution, the structures in mining area and the structures in mine for the gas occurrence in Pingdingshan mining area by using structural level-control theory, and put forward the gas occurrence features under stepwise tectonic control. Meanwhile, the high gas setting of gas occurrence is established by the regional tectonic evolution, while the gas occurrence regularity of high content in the east and low content in the west and symmetrical distribution in Pingdingshan mining area is controlled by Likou syncline. Moreover, the gas distribution is different in different zones and different coal seams in a mine, and the gas occurrence is controlled by the structures in the mine area. The result has provided theoretic guidance for gas occurrence distribution forecast and coal and gas outburst control.
