Patent ID: 7063657

Claim:
A stratum disposal method for disposal of waste matter in a disposal space in an underground gallery, comprising the steps of: excavating a vertical shaft or an inclined shaft through the ground to communicate with said underground gallery, providing an air carrying pipeline within said shaft at the time of shaft excavation, extending said pipeline within said shaft during continued excavation of the shaft, providing a carrying container to be pneumatically carried within said pipeline, transporting shaft excavation debris from said shaft to ground level by pneumatically carrying said excavation debris placed in said carrying container through said pipeline, transporting materials and equipment for use in excavating said shaft by pneumatically carrying said materials and equipment placed in said carrying container through said pipeline, whereby said shaft is constructed by repeating the steps of excavating said shaft, extending said pipeline within said shaft and transporting said excavation debris to ground level through said pipeline, excavating said underground gallery communicating with said shaft, transporting excavation debris from the excavation of said underground gallery to ground level by pneumatically carrying said excavation debris placed in said carrying container through said pipeline, transporting materials and equipment to the underground gallery by pneumatically carrying said materials and equipment placed in said carrying container through said pipeline, whereby the underground gallery is constructed by repeating the steps of excavating said underground gallery and transporting excavation debris from said underground gallery to ground level through said pipeline, disposing said waste matter in a buffer material surrounding the waste matter in an air-tight integrating container at ground level, pneumatically carrying said integrating container having said waste matter and buffer material therein through said pipeline to said underground gallery, and positioning and burying said integrating container having said waste matter and buffer material therein in said disposal space in said underground gallery.
