摘　　要：为查清多金属矿复杂构造及矿体深部延伸情况,选择高精度二维地震法进行勘探试验。试验首先选择合适的激发参数,然后采用高覆盖次数、双线接收采集高质量数据,最后精细化处理成图,对地下构造情况进行揭示。二维地震法正确圈定了火山机构分布范围,揭示了隐爆角砾岩筒的倾向及深度,查明了整体构造情况,探明了矿体的深部延伸情况,应用效果较好。In order to find out the complex structure and deep extension of polymetallic ore body,high precision two-dimensional seismic method is selected for exploration test.Firstly,the appropriate ex⁃citation parameters were selected in the experiment,and then the high-quality data were collected by us⁃ing the high coverage times and double-line reception.Finally,the fine processing was performed to reveal the underground structure.The two-dimensional seismic method correctly delineates the distribution range of volcanic institutions,reveals the tendency and depth of cryptoexplosive breccia pipe,identifies the over⁃all structure,and explores the deep extension of ore bodies.The application effect is good.
