“…Resources comprise the estimated amount of coal in the subsurface. Typically, thickness maps have been used for assessing resources, either using: a) interpolation (Starks et al, 1982;Schuenmeyer and Power, 2000;Tercan and Karayigit, 2001;Watson et al, 2001;Koike, 2008a and2008b;Tercan et al, 2013;Saikia and Sarkar 2013), or b) geostatistical simulation methods (Costa et al, 2000;2001a and2001b;de Souza et al, 2004;Olea et al, 2011;Olea and Luppens 2012;Hohn and Britton, 2013;Cornah et al, 2013;Pardo-Iguzquiza et al, 2013). Interpolation methods applied in this context are appropriate when the goal is to provide a unique composite global estimate for resources.…”

“…The next levels of complexity use a coal proportion map (2D-Pro, Figure 4B) or directly the common coal thickness map approach (2D-Thick, Figure 4C) (Starks et al, 1982;Schuenemeyer and Power, 2000;Hohn and McDowell, 2001;Tercan and Karayigit, 2001;Heriawan and Koike, 2008b;Saikia and Sarkar, 2013). For computing coal volumes using a coal proportion map the total thickness map of the coal zone ( Figure 4A) is also used.…”

“…CO 2 /CH 4 sorption ratio was reported to be 10:1 for low-rank coal and less than 2:1 for low-and medium-volatile bituminous coals (Deng et al 2015). Variation in gas sorption capacity of coal based on proximate analysis, ultimate analysis and maceral contents has been reported elsewhere (Saikia and Sarkar 2013;Ghosh et al 2014). The sorption isotherm gives estimated retention capacity of gas at in situ temperature and pressure of reservoir.…”

“…Geostatistical modeling was conducted for quantification of error associated with reserves estimation at Jharia coalfield, India. The uncertainty maps were generated using kriging variances and areas of high uncertainty were identified for additional sampling for precise estimation (Saikia and Sarkar, 2013). Hindistan et al (2010) conducted case study on dilution problem at an underground coal mine in Turkey.…”
