岩浆侵入对煤矿生产影响极大，淮北煤田卧龙湖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。卧龙湖煤矿自侏罗纪以来岩浆活动剧烈，发生了中性岩浆的侵入，多以岩床形式顺层侵入煤层顶底板及煤层中间。本文基于矿区钻孔数据揭露的岩浆岩分布情况，分析了结果表明卧龙湖矿区岩浆侵入规律，受煤层的形态、结构、理化性质以及产状的控制。

Magmatic intrusion has great effect on coalmine production. The Wolonghu coalmine in the Huaibei coal field is one of those severely affected by magmatic intrusion,where geological structure is major factor controlling magmatic intrusion and distribution of magmatic rocks. The Wolonghu coalmine has been subjected to intermediate magmatic in-trusion since Jurassic as a result of intensification of magmatic activities,and it largely invaded into the roof,floor or between seams. Based on distribution of magmatic rocks disclosed by drilling,this paper analyzed the data and conclud-ed that the magmatic intrusion is confined by form,structure,physical and chemical nature and occurrences of the coal seams.
