卧龙湖矿区岩浆岩侵入煤层的综合解释

Integrated Interpretation of Magmatic Rock-intruded Coal Seam in Wolonghu Mining Area

根据卧龙湖矿区的地层特征构建了岩浆岩侵入煤层模型,并进行地震数值模拟,证明煤层与岩浆岩在波阻抗、波形特征、频谱等多个地震属性上存在差异,表明地震属性差异是应用岩性解释方法区分岩浆岩侵入带的理论基础。在此研究基础上,通过对卧龙湖矿区实际地震资料进行岩性处理与解释,综合预测了该矿区8煤层的岩浆岩侵入范围,为煤矿的安全生产起到指导作用。

A model of magmatic rock- intruded coal seam was built according to the stratigraphic characteristics of Wolonghu Mining Area and the seismic numerical simulation of it was carried out,it was proofed that there were many differences in seismic attributes between the coal seam and magmatic rock,including the wave impedance,waveform features,frequency spectrum and so on. It showed that the differences of seismic attributes were the theoretical foundation of using the lithologic interpretation method to distinguish the magmatic intrusion zone. On the basis of this study,comprehensive prediction was made on the magmatic rock intrusion in 8thcoal seam in Wolonghu Mining Area through the lithologic procession and interpretation of the seismic data in this area,so it can play a guiding role for safe production in the coal mine.
