摘　　要：三维地震勘探是一项非常成熟的探测煤田地下隐伏构造的有效技术手段,用于三维地震勘探解释的软件也层出不穷,但大多数软件需要在工作站上进行安装,对计算机配置要求较高,对于长期出差的一线工作人员来讲,一款可以在普通笔记本电脑上安装的软件非常实用。VVA地震属性解释软件可以在普通计算机上进行安装,操作方法简便、解释手段灵活、地震属性丰富、显示界面多样,基于此,以官庄河煤矿为研究对象利用VVA地震属性解释软件提取多种地震属性、断裂似然体分析、谱分解分析等,充分应用其多样化的显示窗口,结合地质资料,通过地震时间剖面和地震属性进行多方位、多角度对比分析,对煤田隐伏构造进行解释,最终,准确解释了11号煤层隐伏断层3条,隐伏陷落柱3个,采空区2处,解释成果可靠,均得到了矿方的验证。Three-dimensional seismic exploration is a very mature effective technical means to detect underground concealed structures in coalfields. There are also a lot of software for three-dimensional seismic exploration and interpretation. But most of the software needs to be installed on workstations, which has high requirements for computer configuration. For front-line staff who have been on business for a long time, a software that can be installed on an ordinary laptop is very practical. The VVA seismic attribute interpretation software can be installed on an ordinary computer. The operation method is simple, the interpretation method is flexible, the seismic attributes are rich, and the display interface is diverse. Based on this, Taking Guanzhuagnhe Mine as the research object,the VVA seismic attribute interpretation software was used to extract a variety of seismic attributes, fractured likelihood analysis, spectral decomposition analysis, etc., and its diversified display window was fully applied. Combined with geological data, through the multi-directional and multi-angle comparative analysis of seismic time profile and seismic attributes, the hidden structure of coalfield was explained. Finally,three hidden faults, three hidden collapse columns and two goafs in No.11 coal seam were accurately explained, and the interpretation results were reliable. All of which have been verified by the mine.
