A method for dust suppression for an autonomous drilling machine operating at a work site. The method comprises of generating by a perception module perception data of the work site, receiving at least one machine parameter from a machine sensor of the autonomous drilling machine, predicting by a controller a dust level for the autonomous drilling machine at the work site based on one of the perception data or the machine parameter, determining a fluid discharge rate for a fluid discharge unit based on the predicted dust level, and adjusting the fluid discharge rate based on dust level detected during the drilling operation.
