Geological sampling device based on stope blast hole drilling cuttings production and use method thereof

The invention provides a geological sampling device based on stope blast hole drilling cuttings production and a use method thereof, and relates to the technical field of mine sampling. Comprising a sampling barrel and a sampling rod used for lifting drilling cuttings, a sampling groove is formed in the sampling barrel, and a stratified sampling cavity used for stratified sampling of the blast hole drilling cuttings is integrally formed in one side of the inner wall of the bottom of the sampling groove. According to the geological sampling device based on stope blast hole drilling cuttings production and the use method thereof, through the arrangement of a plurality of groups of sample storage grooves in the layered sampling cavity, blast hole drilling cuttings with different depths can be fed into the plurality of groups of sample storage grooves from an opened sample inlet in cooperation with the rotation of a sampling rod after a sampling barrel goes deep into a blast hole; the drilling cuttings sampling d
