Abstract
A method for binding dust generated when rock drilling, by mixing said dust with a liquid. The apparatus to perform the method includes a mixing chamber (6) connected to a dust-separating means (1, 3); means for passing gravitationally to the mixing chamber (6) batches of dust collected in the separating means; and means (12) for supplying a liquid binder to the mixing chamber in an amount corresponding to the size of the batch of dust in question. Arranged in the mixing chamber (6) are means (7, 8) for mixing the dust and liquid by agitation while the next batch of dust is being collected in the separating means (1). The resultant mixture is discharged prior to the next batch of dust being supplied to the mixing chamber.
