【摘要】 在煤田三维地震采区,现代机械化综采系统的生产能力和效益在很大程度上依赖于对小断层的精确解释.介绍了煤田三维采区小断层的3种解释方法:彩色变密度剖面识别法、连续的多线对比识别法、断层立体解释法.以山西省寺河煤矿为例,对这3种解释方法进行了详细的解剖.研究表明,彩色剖面显示技术、倾角控制下的相干体技术,配合断层立体解释技术和连续多线对比识别技术,可以较精确地解决煤田三维采区小断层的预测问题,为煤矿安全高效生产提供技术支持.更多还原

【Abstract】 The productivity and efficiency of modern integrated miming system mostly depend upon the interpretation accuracy of small faults in coalfield 3D seismic survey. In this paper, the authors introduced 3 kinds of methods for small faults interpretation: the variable density profile, multi-lines comparison, and 3D faults depiction in 3D seismic survey of coalfield. As a case study, the authors interpreted the distribution of small faults in Sihe W-2 mining block, Jincheng coalfield. The results show that small faults in seismic survey of coal mining block can be identified accurately by the integration of the following techniques: the variable density profile magnification, the coherence cube controlled by steering, along with the 3D faults depiction and multi-lines comparison. These techniques are helpful for the high productivity and efficiency of coal mining industry.更多还原
