摘要 淮南矿区十多年来开展的煤矿采区三维地震面积达到254.56 km2,占井田面积的46.14%。通过对以往三维地震成果1 030个验证点的统计分析,拟定了三维地震成果验证准确率的评价标准;据此得出常规三维地震勘探对13-1煤层中3 m以上断层解释的准确率达62.38%,11-2煤层中2 m以上断层解释合格率约46.74%;而高密度三维地震勘探对11-2煤层中2 m以上断层解释的准确率达到85.71%。结合实例研究,分析了小断层、煤层变薄区在三维地震资料上的显示特征与探采对比效果。 3D seismic survey has been carried out in 254.56 km^2 in Huainan coal mine area, which took up 46.i4% of the total coal mine field. After analyzing the 1 030 verification points of the 3D seismic surveys we did in the past, we set up a standard for evaluating the accuracy of the 3D seismic interpretation results. Using this standard, we found that the accuracy can reach 62.38% when interpreting the faults of more than 3 m in 13-1 coal seam using general 3D seismic survey, and the accuracy changes to 46.74% while interpreting faults of more than 2m in 11-2 coal seam, but when applying high density 3D seismic survey to interpret faults bigger than 2m in 11-2 coal seam, this accuracy can increase to 85.71%. Based on case study on comparing seismic survey with mining, we analyzed the characteristics of small and median faults and thin-out belts of coal seam on the 3D seismic profile, and checked the validity.
