A method of assessing the effectiveness of a dust control in reducing dust at one or more locations (201-213) in a mine, the method comprising the steps of: installing (301) a dust meter each location (201-213); mining ore for a control-deactivated period with the dust control deactivated (302); determining a control-deactivated dust level having regard to an amount of dust measured at one or more of the dust meters during the control-deactivated period (303); mining ore for a control- activated period with the dust control activated (304); determining a control-activated dust level having regard to an amount of dust measured at the one or more of the dust meters during the control-activated period (305); and comparing the control-activated dust level with the control-deactivated dust level (306). |
