摘　　要：为了提高黄土塬区地震勘探的精度,为煤矿生产提供更为准确的资料。针对黄土塬区地震勘探的特点和主要技术难点,阐述了采用直线与弯线联合、二维直线三维观测、改善激发条件、优选观测系统、增加覆盖次数以及多域迭代静校正等相应的有针对性的技术措施。提交资料后经过钻孔验证,结果表明:采用该勘探方法观测系统合理、激发条件选择得当以及资料处理流程搭配合理、解释方法正确,资料的准确程度较高,取得了理想的地质效果。In order to improve the accuracy of the seismic exploration in the loess tableland area and to provide more accurate information to the mine production, according to the seismic exploration features and main technical difficulties in the loess tableland area, the paper stated the applications of the combination with the linear and curved line, 2D linear and 3D observation, improved excitation conditions, optimized survey system, increased cover numbers, multi iterative static correction and relevant targeted technical measures. After the in- formation provided and the borehole inspections, the results showed that the survey system was rational, the excitation conditions was ap- propriately selected, the match of the information processing procedure was rational, the explanation method was correct, the curacy of the information was high and the expected geological results were obtained.
