摘　　要：煤矿安全高效生产对三维地震勘探精度要求越来越高,如何进一步提高勘探精度,设计思路、采集方法、处理和解释过程中的每个环节都至关重要。煤矿采区高密度三维地震勘探采用数字检波器接收,观测方式为全方位、高密度、大偏移距,获得更接近理想波场的信息;采用宽频带处理,获得宽频带、高保真度的数据体,为解释工作打下良好基础。以淮北矿区近年施工的高密度三维地震勘探工程为例,从观测系统设计优化、处理解释思路及方法、工程施工过程控制等方面入手,总结出一套煤矿采区高密度三维地震勘探新模式,对进一步提高煤矿采区三维地震勘探精度以及为煤矿采区设计、工作面开采提供详实的地质保障基础资料具有一定的意义。Safe and efficient production of coal mine requires higher and higher precision of 3D seismic exploration.How to further improve the precision of exploration,design ideas,acquisition methods,processing and interpretation of each link are of vital importance.High density three-dimensional seismic exploration in coal mining districts adopts the reception by digital detectors.The observation method is of omni,high density and large offset,so that the information closer to the ideal wave field can be obtained.Broadband processing is adopted to obtain the data body with broadband and high fidelity,which lays a good foundation for interpretation,the high density three-dimensional seismic exploration projects in Huaibei mining area in recent years were taking as an example,from the observation system design optimization,the train of thought and method of processing and interpretation,the project construction process control and other aspects,a new pattern of high density three-dimensional coal mining districts seismic exploration was summed up,which has certain significance for further improvement of the precision of 3D seismic exploration,providing detailed basic geological guarantee data for the design of mining districts and mining in working faces.
