摘要
通过郭二庄井田岩浆侵入体的详细调查,分析了岩浆侵入体的分布特征及侵入规律,岩体呈岩盘侵入,似层状,局部有岩脉或岩柱状。岩浆岩的侵入破坏了煤层的连续性和完整性。结合岩浆岩与构造的关系分析了岩浆侵入对煤层的破坏方式和破坏程度,结果表明本区岩浆岩对煤层的破坏可分为3种情况,即使煤层出现分岔、变薄甚至全部被吞蚀。
Distribution characteristic of magma intrusion body and intrusion rules was analyzed by detailed survey of magma intrusion bodies in Guoerzhuang minefield.The rock body was intruded,taking on rock-plate,like sandwich and there was dyke and bysmalith in local area.Magma intrusion broke continuity and integrality of coal-seam.Combined with the relationship or magma and tectonic,broken type and degree of coal-seam by magma intrusion was analyzed.Results showed there were 3 broken types including fork,fining down and even vanish of coal-seam.
