A method of constructing underground galleries using a pneumatic transfer system and a stratum disposal method are provided, wherein in constructing disposal galleries, mountain tunnels or the like in a stratum disposal site or in performing stratum disposal of waste matter, the carrying-out of excavation chips or the like and carrying-in of materials and equipment or the like and the carrying-in and positioning of waste matter can be effected safely, quickly and reliably at low cost, and the quality of buffer material for waste matter can be secured. In construction, an air carrying pipeline (10) is used while extending the air carrying pipeline (10) downward as desired during the excavation of a vertical shaft (2a) so as to carry out vertical shaft excavation chips (a) to the ground and carry in materials and equipment including vertical shaft spray concrete (b) to the underground site. Alternatively, the vertical shaft itself is used as the air carrying pipeline (10), and by using the air carrying pipeline (10) extending from the vertical shaft (2a) to an underground gallery (3), excavation chips (a) from the underground gallery (3) are carried out to the ground and materials and equipment for the underground gallery are carried in to the underground site. In operation, the air carryingpipeline (10) is used to carry in a carrying container (11) having the waste matter (A) and a buffer material (B), which are integrated together, stored therein, to the underground side, and the integrated waste matter (A) and buffer material (B) are positioned and buried in a disposal hole (7).
