一、序言煤包作为岩浆岩侵入区内煤层的一种特殊而且十分重要的赋存形式,已被近年来许多矿井的开采事实所证明。利国矿区建矿十五年来,共采出250万吨煤炭,其中煤包采煤量竞达125万吨,占总数的50％。为了对岩浆岩区煤层实行更有效的勘探和开发利用,本文专门对利国地区煤包赋存特征以及它的形成机理进行了探讨。以便进一步深入研究岩浆岩破坏煤层的规律,供岩浆岩侵入区的煤田勘探、开采工作参考。
I. INTRODUCTION Coal bag, as a special and very important form of occurrence of coal seam intrusion into magmatic rocks, has been proved by the fact that many mines have been exploited in recent years. In the 15 years since the founding of Liuguo Mining Area, a total of 2.5 million tons of coal have been mined, of which 1.25 million tons of coal have been pumped into coal mines, accounting for 50% of the total. In order to carry out more effective exploration and exploitation of coal seams in magmatic rock area, this paper discusses the characteristics of coal deposit in Libya area and its formation mechanism. In order to further study the law of the magmatic rocks destroys the coal seam for the magmatic rock intrusion zone coalfield exploration and exploitation reference.
