| dc.description.abstract | In this report, the recommended minimum systematic support and pillar dimensions have been detailed per mining area along with the anticipated amounts of contamination. Challenges are expected in areas in which the roof and floor strata as well as the coal seam itself are impacted on by the effects of dolerite intrusions. The minimum mining depth cutoff which has been applied in this investigation is 20 m. Although areas in which the mining seam lies at depths of between 20 m and 30 m are deemed to be potentially minable based on the available geological and geotechnical information, it is recommended that additional drilling and geotechnical testing be conducted in these areas to verify the rockmass properties of the overburden before mining is conducted in them. Since multiseam mining will be conducted in a significant portion of the Schurvekop project area, the design guidelines for multiseam mining must be complied with. As a result, it has been found that the barrier pillars on the No. 4 Lower Seam and No. 2 Seam in the northern portion of the project area will have to be superimposed. Additional investigations using numerical modeling techniques could be conducted to confirm / refute the need to superimpose the barrier pillars on the Two (2) seams in this portion of the project area. | |
