摘　　要：保安井田位于太行山复背斜之西翼,沁水煤田之东北边缘,阳泉矿区西部。勘探区内断层和褶曲发育,煤层埋藏深度和岩层倾角变化较大;地面山高坡陡,冲沟发育,最高点与最低点最大相对高差337 m,区内主要有4个山梁穿过,分布多个地面障碍物。针对本区复杂的地震地质条件,通过不断优化勘探设计和外业场地试验,最终确定野外数据采集观测系统和施工方法,并在资料解释处理时,选择合适的处理技术、处理参数及处理流程,获得高信噪比、高分辨率的三维数据体,较好地完成了地质勘探任务。The Baoan mining field is located in the west wing of Taihang Mountain anticline,the northeast edge of Qinshui Coalfield,and the west of Yangquan mining area.Faults and folds are well developed in the exploration area,and the buried depth and dip angle of coal seam vary greatly.The slope of the mountain is high and steep,and the gully is developed.The maximum relative height difference between the highest point and the lowest point is 337 m.There are mainly 4 mountain beams passing through the mining area,and multiple ground obstacles are distributed.In view of complex seismic geological conditions in this mining area,through continuous optimization of the exploration design and field test,finally determined the field data acquisition system and the construction method for observation,and explained in data processing,choose suitable processing technology,processing parameter and processing procedure,and obtained high signal-to-noise ratio,high resolution 3D data volume,better finished geological exploration task.
