Drilling apparatus and method for collecting research sample

A drilling apparatus, which comprises

• a drill;
• a dust removal pipe for removing dust created in drilling from a proximity to a borehole;
• and
• a sampling apparatus for collecting research sample in the dust removal pipe of the drilling apparatus, the sampling apparatus comprising:
• a sampling pipe arrangement, wherein at the end of sampling pipe arrangement there is a sampling pipe, and wherein a mouth aperture of the sampling pipe is fitted in the dust removal pipe;
• an element for fixing the sampling pipe arrangement to the dust removal pipe;
• a suction device configured to form suction in the sampling pipe;
• a collecting arrangement fixed to the sampling pipe arrangement for separating sampling material from the air flowing in the sampling pipe arrangement and for collecting sampling material;
• a length adjustment apparatus for moving the sampling pipe in the longitudinal direction in the dust removal pipe;
• and
• a rotating apparatus for rotating the sampling pipe in the dust removal pipe,
• wherein one end of the sampling pipe is fitted into the dust removal pipe and the other end of the sampling pipe is outside of the dust removal pipe and connected to the suction device which is provided outside of the dust removal pipe, and
• wherein the sampling apparatus is configured in such a manner that the dust is sucked into the sampling pipe by the suction device, and is conveyed to the collecting arrangement through the sampling pipe.
