| 摘 要： | 通过对祁东煤矿勘探钻孔统计资料分析．研究了岩浆侵入煤层的主要特征。岩浆主要以岩床的形式沿煤层侵入，岩性以云煌岩为主，岩床层数多为一层，岩浆主要是顺煤层上部侵入。从上部煤层到下部的10煤层，岩浆侵入活动呈现出从无到有、从弱到强的趋势；分布区域从西向东、由北向南扩展，分布面积逐渐扩大。岩浆侵入破坏了煤层的结构和稳定性，其接触变质作用造成煤类分布混杂，而仅靠钻孔不可能完全查明岩浆岩的分布形态，建议今后加强矿井地质观测，为煤炭开采提供服务。

| Abstract: | Based on the statistics of exploratory boring data, the main characters are researched on magmatic intrusion in Qidong coalmine. Magma intruded into coal seams was mainly in the form of minette sills, mostly single layered, concordant intrusion along the coal roof. From upper coal seams to the No.10 coal in the lower part, magmatic intrusive activities from nothing to weak then strong, and from west to east, north to south, the distribution area expanded gradually. The intrusion destructed coal seam texture and stability; contact metamorphism caused mingling distribution of coal ranks. The fully investigation of magmatic rock distribution cannot be relied only on drilling, it is advised that the mine geological observations have to strengthen from now on, thus providing services for coal mining. |
