地震勘探对地下地质结构的调查是一种行之有效的方法。但由于条件的限制 ,有些地区不适合采用炸药震源 ,而且炸药震源费用高、危险大 ,所以采用电磁驱动可控震源。为验证可控震源野外工作的稳定性、可靠性、有效性 ,在河北省迁安大石河铁矿进行了实际探测 ,通过与夯击震源对比 ,可控震源较夯击震源具有更高的分辨率 ,并可以自由选择频率范围 Seismic exploration of the geological structure of the underground survey is an effective method. However, due to the limitation of conditions, explosives sources are not suitable for some areas, and explosives source costs are high and dangerous. Therefore, electromagnetically driven vibrators are used. In order to verify the stability, reliability and validity of field work of Vibroseis, the actual exploration was carried out in Dashihe Iron Mine, Qian’an, Hebei Province. Compared with the tamping source, the Vibrator has a higher resolution than the tamping source Rate, and the freedom to choose the frequency range
