DESIGN Point 1.1 1.2 1.3 1.4 1.5 1.6 Standard Guideline The design is such that potential instability due to the physical properties of Intent : To verify compliance with MSIR 13.5(1)(a) for new and expanding the material dumped is minimised. structures. Waste dumps and heap leach dumps etc must last forever and constitute far greater volume than mineralised material, for which physical properties should be known from mine feasibility and planning studies. Personnel : Geotechnical engineers, mine planning engineers, geologists, Quarry Manager. Method : View technical and design documentation. The design is such that potential instability due to the size and weight of Intent : To verify compliance with MSIR 13.5(1)(b) for new and expanding the equipment used is minimised. structures. Compaction of dumped material will relate to type and size of equipment used in construction. This should have been considered in the planning stage. Personnel : Geotechnical engineers, mine planning engineers, geologists, Quarry Manager. Method : View technical and design documentation, future equipment plans. The design is such that potential instability due to natural terrain and Intent : To verify compliance with MSIR 13.5(1)(c) for new and expanding ground stability is minimised. structures. Old underground workings, natural drainage channels, soft, weak soils, etc. can all produce problems for dumps located on them.

Intent : To verify that possible dust generation within the operation is properly managed. Prevailing winds should not carry dump dust over haulroads, pit or plant operations, offices, workshops, camp, towns, public roads, etc. Material with special dust problems may require constant watering with sprays. Personnel : Geologists, mine planning engineers, environmental engineers, ventilation officer, Quarry Manager. Method : View technical and design documentation and plans. 1.8 The design is such that hazards due to drainage contamination are Intent : To verify that any potential contamination is properly managed. . The minimised. potential for acid rock drain water must be assessed and dealt with if required. Other water borne contaminants may leach out. Personnel : Geologists, mine planning engineers, environmental engineers, Quarry Manager. Method : View technical and design documentation, plans etc. 1.9 The design is such that hazards to other infrastructure from instability are Intent : To verify that new and expanding structures are appropriately located. minimised. There must be no potential risk to offices, workshops, power lines, roads, railways, houses, magazines, etc. Personnel : Mine planning engineers, surveyors, Quarry Manager etc. Method : View plans. 2. LAYOUT Point 2.1 Standard Day and night effective route marking is provided for approach to tipping areas. 2.2 Demarcated access and exit routes are used to separate traffic flows. 2.3 Turning and reversing areas are compatible with the largest equipment used. 2.4 Traffic control measures are implemented on site. Guideline Intent : To verify compliance with MSIR 13.5(3) for all existing structures. Personnel : N/A Method : Visually inspect facility for adequacy. Look for route and dumping area demarcation and provision for night dumping. Intent : To verify that traffic hazards are properly managed. To prevent traffic congestion, especially at ROM pads. Written procedures required. One way systems are also possible on large dumps and confine movement to defined roads thus reducing grading and watering requirements. Personnel : Quarry Manager Method : Visual inspection of dump areas and written procedures. Intent : To verify that driving hazards are properly managed. Written procedures where dozers and/or loaders are permanently used are required. Personnel : Quarry Manager Method : Visual inspection of dump areas and written procedures. Intent : To verify that traffic hazards are properly managed. Written procedures are required. Can incorporate light vehicle lanes, roundabouts, traffic lights, etc. To verify compliance with MSIR 13.7(4). Personnel : Quarry Manager Method : Visual inspection of dump areas and written procedures. Page 169 Department of Industry and Resources Safety, Health and Environment Division 2.5 Access is restricted to bottom of tipping area. Intent : To verify that the hazards of free falling material on slopes are properly managed. Access is required for inspection of toe and in an emergency but should be restricted for only these purposes due to hazards from rocks rilling down. Personnel : Quarry Manager. Method : Visual inspection.________________________________________________ 3. OPERATION Point 3.1 3.2 3.3 3.4 3.5 3.6 3.7 3.8 Standard Guideline Where no spotter is used, an effective back stop is provided. Intent : To verify compliance with MSIR 13.5(2). Windrow or backstop should be half truck tyre height and not show signs of being used for stopping. Personnel : Quarry Manager Method : Visual inspection for adequacy. Where night time tipping is carried out, the work area and dump edge are Intent : To verify compliance with MSIR 13.5(4) illuminated by stationary lighting. Personnel : Quarry Manager. Method : Visual inspection for presence of lighting plant. Each working shift the dump edges are inspected for evidence of instability. Intent : To verify compliance with MSIR 13.5(5) There should be written inspection duties for supervisors and shift logs (samples required). Personnel : Supervisors, truck operators etc. Method : Interview personnel and procedure/record check. Simultaneous dumping over the edge of a stockpile and loading out from Intent : To verify compliance with MSIR 13.5(6). There should be written the base is only carried out at sufficient separation such that undermining procedures and physical signs, barriers where carried out. of the dumping location is not possible. Personnel : Quarry Manager, supervisor and operators etc Method : Visual inspection for adequacy and procedure check. There are written procedures for tipping. Intent : To verify that personnel are instructed. Personnel : Quarry Manager, Training officer, supervisor, operators etc. Method : View procedures for haultrucks, dozers, loaders, spotters, etc. (samples required) interview personnel. Operators of equipment are tested on the procedures before being Intent : To verify that personnel are deemed competent. authorised to tip. Personnel : Quarry Manager, Training officer, supervisor, operators etc. Method : Written and practical competency test sheets and results (samples required). Interview personnel. There is restricted access to the tipping area for light vehicles and Intent : To verify that traffic hazards are properly managed. personnel. Personnel : Quarry Manager and operators.
