摘　　要：为了保证车寨矿井首采区的安全建设及采掘,需对首采区内的构造进行控制。现采用三维地震勘探勘探技术对该矿井的首采区5.106km2范围内进行地面勘探工作。在确定激发条件等施工参数后进行勘探作业,发现勘探区地层总体为一走向近NE,倾向NW,倾角2~12o的单斜构造,在此基础上发育次一级小褶曲3条;断层26条,长轴直径大于25m的陷落柱24个。此次勘探结果一定程度上保证了首采区巷道掘进及工作面回采等安全作业。In order to ensure the safe construction and mining of the first mining area of the Chezhai Mine, it is necessary to control the structure in the first mining area. The 3 D seismic exploration and exploration technology is used to conduct ground exploration work in the area of5.106 km2 in the first mining area of the mine. After determining the construction parameters such as the excitation conditions, the exploration operation is carried out. It is found that the strata in the exploration area are generally a single-inclined structure with a trend of near NE, a tendency of NW and a dip angle of 2 to 12°. On this basis, three sub-scale folds are developed;fault 26 Bars, 24 trap columns with a major axis diameter greater than 25 m. The results of this exploration have ensured safe operation such as roadway excavation and working face mining in the first mining area.
