摘　　要：通过分析曲村勘查区内施工的5个钻孔资料,研究了霍西煤田曲村勘查区岩浆岩发育特征,以及岩浆侵入对煤层的影响。结果表明,勘查区内煤系主要地层均被岩浆岩侵入,产状主要为岩床和岩脉,侵入于中生代燕山期。岩浆岩主要为二长岩和闪长斑岩,均为斑状结构,块状构造,自形程度较好;岩浆侵入使得勘查区主要可采煤层2号煤层和9号煤层大面积被吞蚀,煤质受到影响,工业利用价值降低。研究认为,曲村勘查区煤炭资源开发利用前景一般。By analyzing the data of five drilling hole constructed in Qucun exploration area,development characteristic of magmatic rock and magmatic intrusion influence on coal seam were studied in Qucun exploration area of Huoxi coalfield.The results showed that the main strata of coal measures in the exploration area were intruded by magmatic rocks in the Mesozoic Yanshan period,and the occurrences were mainly bedrock and dyke.Magmatic rocks were mainly monzonite and diorite porphyry,both of which were porphyritic structure,massive structure and good automorphism.Magma intrusion made the main minable No.2 and No.9 coal seams swallowed and immersed in a large area in the exploration area,affected the coal quality and reduced the industrial utilization value.The study showed that the coal resource had a bad prospect of development and utilization in Qucun exploration area.
