Zusammenfassung:	The invention discloses a drainage system for an aerated heap leaching operation which comprises a layer of drainage rock (2) which includes a plurality of spaced apart substantially vertically orientated perforated tubes, preferably strip drain tubes (3) comprising a substantially rectangular cross section with a ribbed structure. Aeration pipes (4) extending horizontally through the drainage rock layer are placed adjacent to the strip drains. L'invention concerne un système de drainage destiné à une opération de lixiviation en tas aérée. Ce système est constitué d'une couche de roche de drainage comprenant une pluralité de tubes perforés orientés sensiblement verticalement et espacés, de préférence des bandes drainantes.
