摘　　要：依据某铬铁矿区地质、物性资料,分别对矿区铬铁矿体、含矿超基性岩体、地质剖面进行地震正演模拟研究,分析对比模拟剖面和实际地震剖面的波场特征,发现实际剖面上存在与模拟剖面含矿位置相似的波场特征,结合地质资料,推测含矿岩体的反射区域,辅助金属矿区地震勘探对矿体的识别。Based on the geological and physical data of a chromite mine area,the seismic forward modeling of the chromite ore bodies,ore-bearing ultramafic rocks,and geological sections in the mining area was carried out to analyze the seismic wave field characteristics of the ore bodies and the rocks.Compared the similarities and differences of the wave field characteristics of the seismic forward modeling sections and the actual seismic exploration sections,the result showed some similarity between them.Combined with geological data,speculated the reflection area of the ore-bearing rock mass,and help seismic exploration to distinguish orebody in the metal mine area.
