本文以新近在几个大型煤矿所开展的三维地震勘探为例 ,扼要论述了煤矿采区的三维地震勘探数据采集和处理技术 ,以及人机联作解释技术 ,并以所获典型成果 ,介绍了应用该技术在煤矿开采的 80 0m浅垂深范围内 ,所能查明的小断层和低幅度小褶曲构造的能力和精度。由于该技术成果精度高 ,勘探周期又短。因此 ,把三维地震技术作为煤矿设计和开采中高度现代化的工具 ,正在成为中国东部地区一些煤矿的标准作法
Taking the recent three-dimensional seismic exploration carried out in several large-scale coal mines as an example, this paper briefly discusses the three-dimensional seismic data acquisition and processing technology and the man-machine cooperative interpretation technique in the coal mining area. Based on the typical achievements obtained, The ability and accuracy of small faults and low-amplitude small folds to be ascertained using this technique in the shallow depth of 80 0 m of coal mining can be ascertained. Due to the high precision of the technical achievements, the exploration cycle is short. Therefore, using 3D seismic techniques as a highly modern tool in coal mine design and mining is becoming the norm for some coal mines in eastern China
