为了研究五凤井田6中煤层瓦斯赋存规律及主控因素,通过对区域地质演化和地质构造特征分析,结合地质勘探时期钻孔探明的瓦斯基础参数、井下采掘过程中揭露的地质构造及采掘工作面的瓦斯涌出数据分析,研究了五凤井田6中煤层瓦斯赋存规律,揭示了地质构造与瓦斯赋存的关系。结果分析表明,褶皱、埋藏深度是影响井田瓦斯含量的主要因素,并进行了t检验。对井田深部煤层瓦斯的赋存状况进行了预测,对井田后期的安全生产有一定的指导作用。
In order to study the gas occurrence rules and main controlling factors of coal seam in No.5 Mine in Wufeng Minefield, by analyzing the regional geological evolution and geological tectonics, combining the gas foundation parameters proved by drilling during geologic exploration, geological structure exposed during underground excavation and The gas emission data of mining face are analyzed to study the gas occurrence rules of No.6 coal seam in Wufeng Minefield and the relationship between geological structure and gas occurrence is revealed. The results show that the fold and burial depth are the main factors that affect the gas content in the mine field, and the t-test is carried out. The prediction of occurrence of deep coal seams gas in Ida field has a certain guiding effect on the safety production in the late Ida field.
