Abstract

This study uses Multiple indicator Kriging estimator based on assayed data acquired from 48 exploration boreholes in Tabas coal mine in order to predict Gas content of coal seams. Results of the estimated block models showed that approximately 12% of the total area has the Gas content of less than 5 (m3/ton) (Low risk), 11% has 5-10 (m3/ton) (Medium Risk) and 15% has 10-15 (m3/ton) (High Risk), while about 62% of total area has the Gas content of more than 15(m3/ton) which is of a high risk. Therefore, according to the experiences from mined panels, in the zones with lower to median gasification risk, it is possible to keep the mining operation running with management and optimization of the ventilation system. However, in the zones with higher gasification rate, demethanization process is mandatory.
