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.
In the coalfield 3D seismic prospecting area, the production capacity and benefit of modern mechanized fully mechanized mining systems rely largely on the accurate interpretation of small faults.Three kinds of interpretation methods of small faults in coalfield three-dimensional mining area are introduced: Method, continuous multi-line contrast identification method and tomographic interpretation method, taking the Sihe coal mine in Shanxi Province as an example, the three kinds of interpretation methods are dissected in detail.The research shows that the color profile display technology, coherence body Technology, combined with fault interpretation of three-dimensional technology and continuous multi-line contrast recognition technology, can more accurately solve the three-dimensional coal mining area of small faults prediction problems for the safe and efficient coal production to provide technical support.
