1、丰城矿区尚庄煤矿B4煤层瓦斯地质规律研究摘要瓦斯是煤在地质历史演化过程中形成的气体地质体。瓦斯作为气体,既有它自身的物理、化学属性,又由于它生于煤层、储存于煤层,所以受着地质演化历史的控制。不同含煤地层、不同煤层都存在着自身的瓦斯地质规律。揭示了瓦斯地质规律,也就揭示了瓦斯赋存分布的分区、分带规律等,也就揭示了瓦斯致灾机理。尚庄煤业位于省丰城市西北的尚庄街道办境,距丰城市八公里,距省会城市60公里。矿有铁路与上支线在梅林车站相接与浙赣线相连,可达全国各地,公路与105国道及昌樟高速公路相连,水路在石上码头沿赣江上可达樟树、等地,下至、等地,交通十分便利。矿区煤矿井瓦斯分布垂直分带平
2、面分区的特征比较明显。影响矿区瓦斯赋存的主要地质因素是煤化作用程度、地质构造、含煤地层岩性、煤层埋深、水文地质条件、煤层厚度、剥蚀强度等关键词:瓦斯,瓦斯地质规律,尚庄煤矿,地质因素GASGEOLOGYRULERESEARCHATSHANGZHUANGCOALMINEOFFENGCHENGJIANGXIABSTRACTThegasisintheprocessofgeologicevolutionhistoryofcoalformationinthegasgeologicalmass.Thegasasgas,bothitsownphysicalandchemicalpropertie
