摘要
宁阳—汶上煤田鲁西井田内的岩浆顺煤层或煤层顶底板侵入,对煤层和煤质都有严重影响。该文分折研究了岩浆岩的侵入层位、层数、厚度、岩性及其矿物成分,初步探讨了岩浆岩的来源、地质时代及其对煤层、煤质的影响。
Magmatic rocks in Ningyang--Wenshang coal mine in Luxi coalfield intruded through strata and roof and floor of coal strata, which will influence coal strata and quality greatly. In this paper, intrusion layers, numbers of intruded layers, intrusion thickness, lithology and mineral composition of magmatic rocks have been analyzed and studied. The origin of magmatic rocks, geological ages and the influences to coal strata and quality have been introduced as well.
