在煤田三维地震勘探中,复杂的地表地形条件,将直接对数据采集质量造成不利影响。本文通过对济宁三号煤矿七采区三维地震勘探施工进行总结,针对现场不同的地表地震条件,通过试验对比,选择良好的激发、接收条件,采取有效的施工措施,确定了合适的野外数据采集参数,保证了野外地震记录质量,为数据处理与解释奠定了基础,取得了较好的地质效果。
In the 3D seismic exploration of coalfields, complicated surface topography conditions will directly affect the quality of data acquisition. In this paper, we summarize the three-dimensional seismic exploration construction in No.7 mining area of Jining No.3 Coal Mine. According to the different surface seismic conditions in the site, we select appropriate excitation and receiving conditions and take effective construction measures to determine suitable field data acquisition Parameters, to ensure the quality of field seismic records, laid the foundation for data processing and interpretation, and achieved good geological results.
