摘要

煤矿采空区地震勘测由来已久,也取得很多经验和成果,而非煤矿山采空区地震勘测是近几年开展比较多的方法技术,由于非煤矿山地层结构不同于一般煤田地层结构,有的矿体成层性差,有的矿体倾角大,有的矿体形状不规则,开采产生的采空区具有分布无规律,形状无规则等特殊性,给三维地震勘测中的资料解释带来一定难度,本文意在总结在多个非煤矿山采空区勘测中的三维地震解释经验,依据地震勘探原理,给出采空区三维地震勘测地震反射波的剖面和平面解释的基本特征,并在实际应用中得到进一步证实,取得良好效果。
        Coal mine gobs have long been under seismic survey, with a lot of experiences and achievements being obtained. For the non-coal mine goafs, in which seismic survey was applied a bit more in recent years, there exists the difficulty in 3D seismic survey data interpretation due to stratigraphic structures of non-coal mines being different from those of general coalfields, poor layering of some ore bodies, great dipping angles of some,irregularity of the forms of some, and ruleless distribution of the goafs. This paper is intended to summarize experiences in 3D seismic interpretations of a number of non-coal mine goafs, according to the principle of seismic exploration, gives basic characteristics of the profiles of seismic reflection waves in the goafs and plane interpretations, which were further verified in practice.
