Abstract: The main characteristics of easy construction under sand, suitable for seepage treatment, low cost in maintenance, long service life, and high-speed construction, the radiation wells for tailings seepage drainage consist of the main well, the radiation filter tube, the aqueduct and the drainage flashboard.The way of determining the parameter in each structural composition of radiation wells are described in detail, and such factors as the length of the dam axis, the scope of infiltration and sabotage and damage level, water levels and the aqueduct path considered in the layout design are introduced.And a preliminary estimation formula on the water output of the whole radiation well is also put forward to determine aqueduct diameter.Finally, the design of radiation well of auxiliary dam in Tongshan mine is introduced briefly, thus providing a favorable reference to the design of radiating well for tailings seepage drainage.
