The important measure to eliminate or reduce the safety risk of tailing pond is to reduce the saturation line in the dam body, and the seepage drainage technology is the main means. Based on the application of some geotechnical engineering technology in the seepage drainage project of tailing pond and with a number of engineering practice, this paper discusses and summarizes the blind ditch drainage, horizontal hole drainage, radiation well drainage, well point pipe drainage and some other combined drainage measures about their principles, characteristics, construction methods and quality control points in tailing pond seepage drainage engineering technology.
