介绍了瓦斯地质异常的主要影响因素:断层、水文地质特性以及煤层埋深等,并用实例分析这些因素的影响机理。提出通过抽采钻孔技术进行瓦斯地质异常勘探,利用抽采钻孔技术能够获得煤层厚度、煤层结构变化等信息,进而采取措施防止瓦斯事故的发生。抽采钻孔的布置与设计会影响到勘探结果,应结合煤矿实际情况合理设计。
The main influencing factors of gas geological anomalies are introduced: faults, hydrogeological characteristics and the depth of coal seams. The influence mechanism of these factors is analyzed with examples. It is proposed that the gas geological anomaly exploration by pumping and drilling technology can be used to obtain the information of coal seam thickness and coal seam structure change by using drilling and drilling technology, and then take measures to prevent gas accidents. Drilling holes layout and design will affect the exploration results should be reasonable design based on the actual situation of coal mines.
