摘要
基于瓦斯赋存构造逐级控制理论,分析了地质构造、上覆基岩厚度、煤层厚度等对瓦斯赋存的影响,确定影响瓦斯赋存的主控因素,并进行了瓦斯含量预测;结合井田构造特点,进行煤与瓦斯区域突出危险性预测。
Based on the tectonic-level-control rule of gas occurrence, the paper analyzed the influence on the gas occurrence from geological structure, thickness of overlying bedrock, and thickness of coal seams. The study also determined the main controlling factors of the gas occurrence and predicted gas content. Combined with coal field structure, the paper made the risk prediction of coal and gas outburst areas. The results showed that normal fault development caused massive gas escape and the thickness of overlying bedrock was the main controlling factor of the methane occurrence.
