There are some methods to estimate coal resources such as polygon and cross section method. Polygon method assumes that coal sediment is a kind of smooth layer, which is constant at certain area and at the point of drilling or outcrop as an axis from influence area. Cross section method assumes that coal thickness between each of section is constant based on the thickness in every sections. Both of the methods do not express the element of geometry of coal sediment in such of real condition in the field. As we known, coal sediments have scraggly condition on the top (roof) and the bottom (floor) of layer, so that they are required to be expressed in an elements of geometry systematically based on the conceptual and mathematical model. <br /> <br /> <br /> <br /> <br /> The paper is devoted to introduce the new concept of an alternative in coal resources estimation. It focused on the application of deterministic method that is realized using finite element method as common platform to evaluate coal resources. The advantage of using the finite element method is that there are possibilities to assign each element with attributes, which are generally used to characterized coal resources such as coal thickness, topography elevation, and coal quality. Beside, it has other advantage i.e. data accuracy that are discritized on the domain solution (coal sediment) and faster process of the solving estimation of coal resources, especially if supported by the finite element based software. <br /> <br /> <br /> <br /> <br /> Research area is located at Pondok Labu Kutai Kartanegara Regency East Kalimantan. Coal exploration has been conducted based on topography map with the scale 1:2000, coal outcrop map, and coal drilling report. Afterward the data will be carried out using finite element method based on conceptual and mathematical model. As comparison, estimation of coal resource also has been conducted by polygon and cross section method.
