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.
