摘　　要：在金属矿坑道找矿中,电法、磁法和电磁法受复杂的地质构造和电磁干扰等影响其勘探精度.而地震勘探随着施工技术的简化和数据处理成本的逐渐降低,加之其探测深度大,信号穿透性强,分辨率高等优势,在金属矿坑道找矿可能具有一定的潜力.为此在云南羊拉铜矿开展以地震反射波法为原理的TSP技术的找矿试验,简述TSP技术的工作原理、数据采集和资料解释的一般流程,结合矿区地质资料解释了本次试验的岩石力学参数成果图、反射层位图和三维速度渲染图等图件,预测了断层破碎带、岩性界面和矿体的位置及空间展布.羊拉铜矿区坑道地震找矿试验表明,该技术在金属矿山坑道找矿有广阔的前景.In the prospecting in metal mine tunnel,the exploration accuracy of electrical,magnetic and electromagnetic methods rather than reflection seismic are affected electromagnetic interference.With the simplification of construction technology and the gradual reduction of data processing costs,seismic exploration can be fully utilized in the prospecting of metal mine tunnels because of its advantages of large detection depth,strong signal penetration and high resolution.Therefore,TSP technology based on seismic wave reflection wave method is applied to the Yangla copper mine in Yunnan province mineral exploration.The working principle,data acquisition and data interpretation of TSP technology are briefly described.Combined with the geological data of the mining area,the results of rock mechanics parameters,reflection horizon map and three-dimensional velocity rendering map are analyzed,and the location and spatial distribution of fault fracture zone,lithologic interface and ore body are finally predicted.Through the experimental study of tunnel prospecting in the Yangla copper mine area,it is shown that this technology has broad prospects in tunnel prospecting of metal mines.
