A drilling apparatus includes a drill and a dust removal pipe for removing dust created in drilling from a proximity to a borehole. The drilling apparatus includes a sampling apparatus for collecting a research sample in the dust removal pipe of the drilling apparatus. The sampling apparatus includes a sampling pipe arrangement, at the end of which there is a sampling pipe, the mouth aperture of which is fitted in the dust removal pipe, element for fixing the sampling pipe arrangement to the dust removal pipe, a suction device for forming suction in the sampling pipe, and a collecting arrangement fixed to the sampling pipe arrangement for separating sampling material from air flowing in the sampling pipe arrangement, and for collecting sampling material. The sampling apparatus includes 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.

A dust suction hood includes a tapered outer cover, a cylindrical outer cover, a tapered inner baffle plate disposed in the tapered outer cover, and a first blocking member matched with an opening in the other end of the cylindrical outer cover. A top opening of the tapered outer cover is matched with an opening in one end of the cylindrical outer cover. A side wall opening of the cylindrical outer cover serves as a dust outlet. A first gap is formed in the tapered outer cover. A first dust suction port is formed between bottom openings of the tapered inner baffle plate and the tapered outer cover. A first drill pipe connecting port is formed in the first blocking member. A drill pipe of the mine drill passes through the first drill pipe connecting port to penetrate the dust suction hood on the drill pipe.

A homogenizer for homogenizing flow, a rock drilling rig, and a method for taking samples is provided. The homogenizer is mountable to a dust collecting system of the rock drilling rig and is arranged for effecting on the flow, which contains air and drilling cuttings. The homogenizer includes a channel part through which the flow is directed and at least one air jet for directing air blows to the flow for generating disturbance in the flow and to thereby homogenize particle distribution of the drilling cuttings in the flow.

A spill container to be mounted below a rig floor. The spill container includes a collapsible concave container having an open top for catching fluid spilled on the rig floor, and a circular bottom opening adapted to receive a tubular member extending through the rig floor and downward below the concave container. The side walls of the concave container extend from the open top to the circular bottom opening. The open top of the concave container has a plurality of hangers extending there about to mount to the rig floor. An outer circumference of the open circular bottom opening has a plurality of hooks attached thereto for mounting to circular rings through which the tubular member extends outwardly therefrom.
