摘　　要：简要介绍了方差体技术原理,以陕北黄陵地区某煤矿为例,在分析该矿地震勘探资料的基础上,利用方差体解释技术对该矿区内煤层冲刷带进行了圈定,根据巷道实际揭露情况,圈定结果准确。应用实例表明,利用方差体技术解释煤层冲刷带时,参与计算的道数和时窗不易过小;解释时应对照钻孔进行约束,必要时需结合时间剖面进行综合分析,以减少多解和误判。The coherence cube technique was introduced simply, and it taking one coal mine of Huangling district of the northern partof Shaanxi province, based on the seismic exploration material was analyzed, then the coal erosion zones of the coal mine was delineatedby coherence cube technique, according the practical situation of roadway exposed, the delineated results was accuracy. The practicalexample showed that the lines and time window that participated calculation should not be small, then restrained according drillinghole as explanation, synthesis analysis should be done with time section as necessity, then multiple solutions and error could be decreased

关 键 词：方差体 冲刷带 振幅 相位
