我国煤层瓦斯赋存与地震带分布的关系

Relationship between seam gas deposit and earthquake zone in China

介绍了我国煤层瓦斯分区分带特点及地震带的分布特征,根据地质力学的观点分析不同构造背景的地震带对煤层瓦斯分区的影响,对比我国各区域煤层瓦斯含量与地震活动性的关系,分析了位于地震带上的煤层瓦斯异常区的形成原因,得出煤层瓦斯含量与地震活动的一般规律。

The paper briefly introduced the block and zone features of the seam gas and the distribution features of the earthquake zone in China. With the view of the geological mechanics, the paper analyzed the earthquake zone with different tectonic background affected to the seam gas block divided. The paper compared with the relationship between the seam gas content and earthquake activity in each mining area of China. The paper preliminarily studied the formation cause of the seam gas abnormal zone above the earthquake zone and summarized the general law of the seam gas content and earthquake activities.
