Environmental Impact Assessment Report: Nkomati Anthracite (Pty) Limited, Madadeni Opencast Mining Project Page 36 4 . 1 . 1 . 5 P o t ab l e W at e r P l a n t No potable water plant will be constructed on site. Potable water will be obtained from a borehole that will be sited and drilled on site. Alternatively, water may be trucked from the existing Nkomati Anthracite Mine offices. 4 . 1 . 1 . 6 M i n e r a l P ro c e s s i n g P l a n t No washing plant will be constructed at Madadeni Opencast Mining area. 4 . 1 . 1 . 7 W o r k s h o p s an d B u i l d i n g s The proposed mining area will be equipped with mobile structures. No workshop and related structures will be constructed on site. 4 . 1 . 1 . 8 T r a n s p o rt Mine officials and senior skilled employees will use their own vehicles for all transport requirements. Where necessary a bus service will be made available to transport other employees from their residence to the mining area. Tipper trucks will be used to transport R.O.M coal from the opencast to the R.O.M coal stockpile area and thereafter to the existing washing plant area. 4 . 1 . 1 . 9 S t o r m W at e r Clean water and dirty water will be separated at Madadeni Opencast as shown in Figure 16. These will be achieved by diversion drains, which will take the form of trenches and berms around the dirty and clean water areas. 4.2 C O N S I D E R AT I O N O F AL T E R N AT I V E S 4.2.1 L a n d U s e Al t e r n a t i v e s No land use alternatives conflicting to the proposed mining operation have been suggested by the land owner or legal land occupier. 4.2.2 P r o j e c t Al t e r n a t i ve s 4 . 2 . 2 . 1 M i n i n g M e t h o d s Due to the depth of the coal seam, opencast mining using the truck and shovel rollover mining method is a feasible method of mining the coal reserve. The only alternative to this is to mine the coal by means of underground mining methods. Underground mining will not be feasible due to the shallowness of the target coal seam and the inability for the roof to support the overlying strata. In view of the above, mining using the underground mining methods will put lives of the employees under serious risks and hence the mining method was discarded.

Environmental Impact Assessment Report: Nkomati Anthracite (Pty) Limited, Madadeni Opencast Mining Project Page 37 4 . 2 . 2 . 2 M i n e r a l P ro c e s s i n g M e t h o d Processing of the minerals will not be undertaken at the proposed mining area. The only alternative to this is to build a new processing plant, which is not feasible since Nkomati Anthracite Mine has a washing plant that can handle the extra tonnage that will be produced at the proposed mining area. The above renders the construction of the processing plant unnecessary. 4 . 2 . 2 . 3 T r a n s p o rt , P ow e r a n d W at e r S u p p l y No employees will be housed at the proposed mining area; employees will be housed in the nearby towns and villages. No alternatives were considered. Ablution facilities will be installed at the proposed mining area, and within the pit area. Employees will be transported from respective residences to the mining premises. Transport for the coal product will be via trucks to the ROM stockpiles and to the Nkomati Anthracite Mine washing plant via existing haul roads. No other alternatives were considered. Transport for the coal product will be via trucks to the ROM stockpiles and to the Nkomati Anthracite Mine washing plant via existing haul roads. No other alternatives were considered. Except for the dust suppression water, no process water supply will be required since no processing plant will be constructed. Potable water will be obtained from a borehole to be sited and drilled on site. 4 . 2 . 2 . 4 M i n e R e s i d u e D i s p o s a l S i t e No coal discard disposal facility will be necessary at the proposed mining area. All coal from the mining area will be transported to the existing Nkomati Anthracite Mine washing plant. The additional coal discard from the coal to be mined at the proposed mining area will be disposed of at the planned coal discard disposal facility. The above-mention disposal facility was designed to have enough capacity to handle the additional coal discard. Waste (domestic and industrial) will be transported to the existing salvage area for sorting, recycling and disposal. NKOMATI ANTHRACITE (PTY) LIMITED COMPILED BY GEOVICON ENVIRONMENTAL (PTY) LTD
