以某煤矿采区二维地震勘探为实例,介绍了在南方地震地质条件较差的地区开展二维地震勘探的施工方法、资料处理方法和解释方法。根据该区二维地震勘探取得的成果,表明在复杂地震地质条件下,合理设置观测系统、注重地震激发和接收方法,运用二维地震勘探方法在查明含煤区的地质构造和煤系赋存形态等方面可以取得较好的地质效果。
Taking a two-dimensional seismic exploration in a coal mining area as an example, the construction method, data processing method and interpretation method for carrying out two-dimensional seismic exploration in areas with poor geological conditions in the south are introduced. Based on the results of 2D seismic exploration in this area, it is shown that under complex seismic geological conditions, the observation system should be set up rationally, the method of seismic excitation and reception should be emphasized, and the 2D seismic exploration method should be used to identify the geological structure of coal-bearing area and coal- Deposit morphology can achieve better geological results.
