摘　　要：通过对金乡矿区的详查地质资料的研究,基本查明了煤层煤质变化规律及岩浆岩对煤层煤质的影响,侵入煤系地层的岩浆岩,以中、酸性的长石斑岩及石英斑岩为主,产生煤层分叉、变薄或全部被吞蚀现象,以及在高温高压的作用下使煤的某些物理性质、化学性质及工艺性能发生变化。Based on preliminary exploration data in Jinxiang mining area, basically found out coal seam and coal quality changing pattern and magmatic impact to coal seam and coal quality. Igneous rocks intruded into coal measures strata are mainly intermediate, acidic feldsparphyre and quartz porphyre, have produced coal seam splitting, thinning or thoroughly corroded off, and variation of physical, chemical properties and technological performances of coal under high temperature and high pressure.
