KML DMP Tipping and Dumping Audit

1.1 The design is such that any future potential instability, due to the physical properties of the material being dumped, is minimised.<br>Intent: To verify that, due to the longevity of such structures, hazards are managed from the design stage. Waste dumps and heap leach dumps etc. are likely to have a long lifespan and can constitute the greater volume of the total material excavated. The physical properties of the material should be known from mine feasibility and planning studies.<br>Method: View technical and design documentation. Refer to MSIR r. 13.5(1)(a).<br><br><br>

1.2 The design is such that any future potential instability in dump material compaction, due to the size and weight of the equipment used during construction, is minimised.<br>Intent: To verify that, due to the longevity of such structures, hazards are managed from the design stage. The compaction results of the dumped material will relate to the type, size and weight of the equipment used in the dump construction. This should have been considered at the planning stage.<br>Method: View technical and design documentation and any future equipment plans. Refer to MSIR r. 13.5(1)(b).<br><br>

1.3 The design is such that any future potential instability, due to the natural terrain and stability of the ground under the area of dump construction, is minimised.<br>Intent: To verify that, due to the longevity of such structures, hazards are managed from the design stage. Old underground workings, natural drainage channels, soft, weak soils, etc. can cause problems in dumps located over them.<br>Method: View technical and design documentation and the natural surface plans. Refer to MSIR r. 13.5(1)(c).<br>

1.4 The design is such that any future potential instability, due to the drainage characteristics of the material being dumped, is minimised.<br>Intent: To verify that, due to the longevity of such structures, hazards are managed from the design stage. Effective long term drainage of the dumped material is an essential part of dump design.<br><br>Method: View technical and design documentation. Refer to MSIR r. 13.5(1)(d).<br><br>

1.5 The design is such that any future potential instability, due to the probable climatic conditions of the area, is minimised.<br>Intent: To verify that, due to the longevity of such structures, hazards are managed from the design stage.

Refer to MSIR r. 13.5(1)(e).<br>

1.6 The design is such that any future potential hazard, due to the presence of hazardous material in the dump, is minimised.<br>Intent: To ensure that, due to the longevity of such structures, hazards are managed from the design stage. The hazards of radioactivity, asbestiform mineral, spontaneous combustion, toxic gas, etc. must be taken into account.<br>Method: View technical and design documentation<br>

1.7 The design is such that the hazards of dust generation from the dump are minimised.<br>Intent: To ensure that dust generation within the operation will be managed. Prevailing winds should not carry dump dust over haul roads, open pit or treatment plant operations, offices, workshops, accommodation camps, offsite buildings, public roads, etc. Material with special dust problems may require constant watering with sprays or other means of mitigation.<br>Method: View technical and design documentation and plans.<br>

1.8 The design is such that the hazards of contamination from dump water drainage are minimised.<br>Intent: To ensure that any potential drainage contamination will be managed. The potential for acid rock water generation must be assessed and dealt with where required. Other water borne contaminants may be carried through and then leach out.<br>Method: View technical and design documentation and plans.<br>

1.9 The design is such that any potential hazards from dump instability, which could affect other infrastructure, are minimised.<br>Intent: To ensure that new structures, and/or the expansions of existing structures, are appropriately located. There must be no potential risk to personnel, offices, workshops, power lines, roads, railways, houses, magazines, etc.<br>Method: View plans.<br><br><br>

1.10 The design is such that any potential hazards from dump instability or tipping activity, which could affect other infrastructure, has a containment bund of sufficient design and size to contain the material via a standard, procedure or risk assessment.<br>Intent: To ensure that old and new structures and/or the expansions of existing structures, are appropriately located. There must be no potential risk to personnel, offices, workshops, power lines, roads, railways, houses, magazines, etc.<br>Method: View plans, standards, procedures and risk assessment documentation.
