The invention relates to the field of combustible ice mining equipment, in particular to a combustible ice extraction pipe column. The combustible ice extraction pipe column comprises a plurality of first limiting holes, a limiting structure, conveying structures, fixed plates and a connecting structure. The first limiting holes for limiting the limiting structure are symmetrically in pairs, linearly and equidistantly arranged in the side walls of the conveying structures which are provided with a cylinder structure and used for conveying combustible ice gas. The limiting structure used for fixing the connecting structure is fixed to the conveying structures. The connecting structure is provided with the four fixed plates which are symmetrical in pairs. The fixed plates corresponding to the limiting structure one by one are detachably connected with the limiting structure. The conveying structures are connected with a circulating pipeline for cooling, the interior of the conveying structures is conveniently cooled in the process of land mining and conveying, the problem that danger is caused, and the conveying quality is affected due to the fact that the internal temperature of theconveying structures is too high is effectively solved, and the conveying quality is improved. The two conveying structures are connected through the connecting structure, so that the conveying structures are more convenient to mount and dismount, and the sealing performance between the conveying structures is improved.
