我国东部煤田普遍存在岩浆侵入现象，其对煤矿安全生产影响极大，因此准确划分岩浆侵入煤层范围是煤炭生产迫切需要解决的关键问题之一。通过分析岩浆岩、天然焦、煤等物性特征，构建地质模型进行正演模拟，证实其在振幅、相位、频率等存在明显差异。以山东某煤矿3煤层为例，利用单属性技术、多属性聚类分析及谱分解技术等结合常规方法，圈定了煤、天然焦分界线及岩浆侵入范围。通过矿方布设的10个钻孔验证，与解释结果比较吻合。

The magmatic intrusion is prevalent in eastern China coalfields, and greatly impacted coalmine safety in production. There-fore, to delineate magmatic intrusion range in coal seams accurately is essential in coal production. Through physical characteristic analyses of magmatic rocks, natural coke and coal to construct the geological model, carried out forward simulation, confirmed signifi-cant differences have existed in their amplitudes, phases and frequencies. Taking the coal No.3 in a Shandong coalmine as example, us-ing single-attribute, multi-attribute cluster analyses and spectral decomposition combined with conventional methods have delineated boundaries between coal and natural coke, as well as magmatic intrusion ranges. Validation through 10 boreholes lay out by coalmine side, compared with the interpreted results they are rather tally with.
