Total sulfur variability analysis of coal deposits using ordinary kriging estimation

Coal's price collapse has become a challenge in exploring and exploiting coal deposits in the mining industry. Total sulfur is one of the coal qualities sufficiently considered in the use of coal. The Geostatistics method using ordinary kriging estimation is done to determine the total sulfur v...

description Coal's price collapse has become a challenge in exploring and exploiting coal deposits in the mining industry. Total sulfur is one of the coal qualities sufficiently considered in the use of coal. The Geostatistics method using ordinary kriging estimation is done to determine the total sulfur variation in the coal seam. Modelling was performed on every three meters of coal thickness using 193 samples on a seam of coal with a thickness of up to 30 meters. Geostatistical modelling is implemented on the coal seam, and it produces ten sulfur distribution models. The modelling results show clearly that in the model in the first layer, the distribution of sulfur is higher in value than other layers. These results expected can help select mining stages and exploration drilling activities in the context of increasing coal reserves.
