Aluminium alloy tubes for pillar for coal mine and a method for preparation, relate to the tubes and a method for preparing the same. The invention solves the problem that the existing tubes for pillar for coal mine have low bearing capacity. The tubes of the invention comprises, based on weight percentage, Si of 0-0.04%, Fe of 0-0.04%, Cu of 0.55-0.99%, Mn of 0.15-0.35%, Mg of 2.6-2.9%, Zn of 4.60-5.20%, and the residuel of Al. The method includes: 1) hollow cast ingot made of, based on weight percentage, Si of 0-0.04%, Fe of 0-0.04%, Cu of 0.55-0.99%, Mn of 0.15-0.35%, Mg of 2.6-2.9%, Zn of 4.60-5.20%, and the residuel of Al; 2) extruding to form hollow tubes; 3) quenching the extruding formed hollow seamless tubes; 4) hot treatment and roller straightening to produce aluminium alloy tubes for pillar for coal mine. The tubes produced by the method of the invention have tensile strength of 470 Mpa, yield strength of 420 Mpa, while wear property and service life of the tubes are improved.
