摘　　要：岩浆侵入对煤矿生产影响极大,淮北煤田卧龙煤矿是受岩浆侵入较严重的矿井之一,其地质构造是控制岩浆侵入和岩浆岩展布的重要因素。基于对岩浆侵入前的地质构造和构造应力场的深入研究,通过从区域构造到井下小构造逐级分析其对岩浆侵入的控制,阐明了研究区构造控制下的岩浆侵入规律。结果表明,NNE向的F7和F5断层控制了岩浆的侵入方向,并与和其交汇的F15断层构成本区岩浆的主要侵入通道。此结果为矿井岩浆侵入区煤层的开采提供了依据。The Wolong coalmine is one of mines seriously influenced by magmatic intrusions in Huaibei mining area,China,in which several coalbeds were intruded into by the magma,which affects regular production of coalmines.Because the geological structures are vital factors controlling the regularities of magmatic intrusions and the distribution of igneous rocks,the tectonic stresses field and geological structures formed before geological time of magmatic intrusions were thoroughly investigated.And then the effects of geological structures controlling the magma intrusion into coal seams were gradually analyzed in the study area from geotectonics to mine structures.Finally,the regularities of magmatic activities were illustrated.The analysis results indicated that the direction of magmatic intrusion was controlled by the NNE-trending faults（F7 and F5）,and the channels of magmatic intrusions were faults F7,F5 and F15 that was intersected by fault F5 besides.
