    The second approach is direct 2-D and 3-D imaging of the sample by different tomographic methods, such as micro- and nano-x-ray microscopy (XRM), scanning electron microscopy (SEM), focused ion-beam scanning electron microscopy (FIB-SEM), and transmission electron microscopy (TEM), among others.

      World population is projected to increase from billion in to – billion in This paper examines whether fossil fuel production can continue to grow to meet the energy demand of this increasing population, even to the extent of increasing production per capita, or whether fossil fuel production per capita will enter a period of continuous decline, necessitating a major. Outcrop studies combined with examination of existing geologic maps and precipitation patterns therefore provide valuable information on coal resources (coal thickness and orientation), ground-water flow and permeability barriers (cleat orientation, fau: coalbed methane, croplands *.

() have developed methods to estimate the uncertainty in well spacings used in deterministic coal resource assessments.

These methods, however, are not a complete probabilistic-based methodology for resource assessment, such as the one currently used in all USGS oil and gas assessments (Charpentier and Cook, ).

However, the reserves are unevenly distributed and located in a small number of states, giving them major influence over future production.

A long history of coal mining provides detailed time series of production and reserve estimates, which can be used to identify historical trends. R oh rb ac e,T.J t sD Suliv nG LdOm M Coal reserves of the Boltsfork quadrangle, Kentucky—A coal recoverability study: U.S.

Coal reserve is a more restrictive term describing the part of the coal resource that can be mined economically, at the present time, given existing environmental, legal, and technological constraints (Wood et al., ).

Coal is the second most important fuel currently used by mankind, accounting for over 25% of the world’s primary energy supply.

It provides 41% of global electricity supplies and is a vital fuel or production input for the steel, cement, and chemical industries. Therefore, this study uses an approach of GIS-based methods (knowledge-driven), mainly fuzzy logic for post-mining land use planning.

The selected mining area for this study belongs to PT. Adaro Indonesia company that has a Work Agreement for Coal Mining Exploitation. Coal will continue to provide a major portion of energy requirements in the United States for at least the next several decades.

It is imperative that accurate information describing the amount, location, and quality of the coal resources and reserves be available to fulfill energy needs.
