摘要
为解决沁水地区煤田陷落柱识别难的问题,以里必煤矿三维地震解释和开采揭露的DX5陷落柱为研究对象,利用地震勘探、钻探、现场揭露等基础资料及综合地质研究成果,基于地震时间剖面解释技术、属性特征分析技术,定性解释了DX5陷落柱在研究区内的空间展布情况。结果表明,在识别里必煤矿陷落柱时属性技术(尤其是带宽属性)优于常规地震剖面解释技术,其方法可靠、有效,为沁水地区陷落柱的识别和解释提供了技术依据。
In order to solve the problem of difficult identification of coal field collapse column in Qinshui area, the No.DX5 collapse column exposed by three-dimensional seismic interpretation and mining in Libi Mine was taken as the research object. Based on the basic data of seismic exploration, drilling, field exposure and comprehensive geological research results, the spatial distribution of DX5 collapse column in the study area was qualitatively explained based on seismic time profile interpretation technology and attribute feature analysis technology. The results showed that the attribute technology(especially the bandwidth attribute) was better than the conventional seismic profile interpretation technology in identifying the collapse column of Libi Mine. The method was reliable and effective, which provided a technical basis for the identification and interpretation of collapse columns in Qinshui area.
