摘　　要：三维地震勘探是一种旨在提高地下目标图像清晰度、位置预测精准性的综合性地球物理勘测技术,近年来被广泛运用于全球油、气、煤等地下资源矿产的勘测中。以新疆玛纳斯县涝坝湾煤矿井田勘探为例,针对区内复杂地形、施工难度大、成孔困难等诸多难题,采用风钻成孔、加水压实等措施,有效提高地震勘探激发效果,获得了较好的原始资料。查明了研究区内各组煤层分布特征,各煤层底板形态基本相似,总体呈东西走向,倾向北的单斜构造,南部浅,北部深。全区可采煤层厚度稳定;查明了区内断层分布情况,新发现3条落差皆小于5 m断层。此次工作为浅层地震条件较为复杂的地区提供经验。3D seismic exploration is a comprehensive geophysical exploration technology aimed at improving the image clarity and location prediction accuracy of underground targets.In recent years,it has been widely used in the exploration of global oil,gas,coal and other underground resources and minerals.Taking the exploration of Laobawan Coal Mine in Manas County,Xinjiang as an example,in view of the complex terrain,great construction difficulty,difficulty in drilling and many other problems in the area,the measures such as air drilling drilling and water adding compaction were adopted to effectively improve the seismic exploration excitation effect and obtain good original data.The geological achievements have been obtained,and the distribution characteristics of each coal seam in the study area have been found out.The floor shapes of each coal seam are basically similar,generally in an east-west trend,inclined to the north,with a monoclinal structure,shallow in the south and deep in the north.The thickness of minable coal seams in the whole area is stable.The distribution of faults in the area has been found out,and three new faults with drop less than 5 m have been found.This work provides experience for areas with complex shallow seismic conditions.
