掌握煤层瓦斯涌出规律,可以为矿井通风设计、瓦斯利用与瓦斯灾害防治提供科学依据,研究瓦斯涌出分布规律具有较大实用意义。运用瓦斯地质理论,依据实际瓦斯涌出资料和地质勘探资料,分析影响宣东矿Ⅲ3煤层瓦斯涌出的各种地质因素。研究发现岩浆岩改变了瓦斯的赋存条件,是影响宣东矿Ⅲ3煤层瓦斯涌出的主要地质因素,宣东矿东南部地质条件复杂,瓦斯赋存条件好,瓦斯涌出量大,煤体受岩浆侵入挤压力破坏,形成瓦斯突出煤体,分析认为井田东南部发生煤与瓦斯突出可能性较大。
Grasping the law of gas emission from coal seam can provide scientific basis for mine ventilation design, gas utilization and gas disaster prevention and control, and has great practical significance for studying the law of gas emission distribution. Based on the gas geological theory and based on the actual gas emission data and geological exploration data, the paper analyzes various geological factors that affect gas emission from coal seam Ⅲ3 in Xuan Tung Mine. The study found that the magmatic rocks changed the gas occurrence conditions, which are the main geological factors that affect the gas emission from the No.3 coal seam in Xuandong Mine. The geological conditions in southeastern Xuan Tung Mine are complex, with good gas storage conditions, large gas emission, By the magma intrusion pressure damage, the formation of gas outburst of coal, the analysis that coal and gas outburst in the southeastern mine is more likely.
