火成岩在煤田地震勘探时间剖面上的解释探索

Study on Igneous Rock Coalfield Seismic Time Profile Interpretation

在火成岩多发的冀中能源章村各个勘探区,结合岩浆喷发和火成岩形成机理,总结各区火成岩解释经验,探讨了火成岩对煤层的原始形态和品质产生的影响,以及岩浆岩侵入区域煤系地层在地震时间剖面上的同相轴变化规律等地震波特征,基本实现了准确判断火成岩区域,对煤系地层的火成岩进行形象化的范围圈定,避免误判,指导矿区采煤施工,并总结火成岩解释原则和规律为以后的解释工作提供借鉴。

Based on Igneous rock coalfield in Zhangcun Mine of Jizhong Energy, combined with the magma eruption and formation mechanism of igneous rock, igneous rock interpretation experience was discussed, igneous rock on the impact of the original shape and quality of coal seam and magmatic intrusion area coal measures strata in seismic time section in phase axis change law of seismic wave eharaeteristies were discussed, which basically realized accurate judgment of igneous rock area and settled the scope of the igneous rock strata, guided the mining area coal mining construction, summary of igneous rock explaining the principles and rules provided reference for the interpretation of the work.
