三维地震属性解释技术在巷道探测中的应用

摘要

The old roadway is a key factor that perplexes the safe production of coal mine in China. This paper carried out forward modeling of roadways, analyzed the reflection and sensitable attributive characteristics of roadway on 2D seismic data profiles. With the 3D seismic exploration in an area of Inner Mongolia as an example and under preconditions of collection of high-quality original data, the actual 3D seismic data were processed by protection processing. Average amplitude, average seismic energy and RMS amplitude attributes were extracted based on conventional interpretation to locate roadway. The interpretation result of roadway location was accurate when compared with coal mining engineering map.%针对煤矿安全生产中老窑巷道的位置和边界难以确定的困扰，对采煤巷道进行正演模拟，分析了巷道在二维地震资料剖面上的反映特征及敏感属性特征。以内蒙某区三维地震为例，在高品质数据采集的前提下，对实际三维地震资料进行保幅处理；在常规解释的基础上提取平均振幅、平均地震能量和均方根振幅等多种属性进行巷道定位解释。最终，解释结果与采掘工程图比对，巷道定位准确。
