| 摘 要： | 岩浆岩侵入体对煤层具有破坏作用，使煤炭资源量减少和矿山开采技术条件复杂化。通过对吴桂桥煤矿岩浆岩体的研究，确定岩浆岩产生于喜马拉雅构造运动时期，岩浆岩岩床、岩脉顺层侵入于石炭系、二叠系及古近系地层中，特别是侵入于煤层中时，使煤层的结构变得复杂，同时使煤层变质程度加深，局部形成高变质无烟煤。

| Abstract: | Magmatic intrusions have destructive effects on coal seams，which reduces the amount of coal resources and complicates the mining technology.Based on the study of magmatic rock in Wuguiqiao Coal Mine，it is determined that magmatic rocks was formed during the tectonic movement of Himalayan，the bed rock intrude into the carboniferous，Permian and the paleogene strata，especially in coal seams，magmatic rocks make structure of the coal seam complicated，and the metamorphic degree of coal seam deepened，create high metamorphic anthracite in some regions. |
