Roof bolt machine with quartz trapping device

A roof bolt machine comprising a quartz trapping device adapted to connect with an exhaust stream of a dust system circuit of a roof bolt machine for reducing the amount of respirable dust and respirable quartz that is released into the environment from the exhaust stream. The quartz trapping device comprises, a container partially filled with a liquid, at least one inlet mounted on said container and adapted to connect the container with the dust system circuit of the roof bolt machine for directing the dust exhaust stream inside the container and a plurality of downward extending and upward extending baffles arranged in an alternating configuration. The baffles form together with the liquid a tortuous path through which the dust exhaust stream is conducted while it contacts the liquid, repeatedly, a number of times sufficient to cause a significant amount of the respirable dust and respirable quartz content of the dust exhaust stream to be captured inside the liquid and form a substantially clean exhaust stream, and an outlet mounted on said container for releasing the substantially clean exhaust stream.
