Resource estimation for Alpagut-Dodurga coal field and determination of spatial distribution of coal quality parameters

In this study, coal seams of the Alpagut-Dodurga coal field, located in one of Anatolia’s most important Tertiary-aged basins ofthe Çankırı-Çorum Basin, were modeled in 3 dimensions by using Netpro/Mine software and geostatistical methods for the estimationof resource amount. Additionally, the spatial distributions of coal quality parameters (lower calorific value, ash content, and moisturecontent) were determined using the same software and mapped thematically. Mining activities with inaccurate methods and planninglead to unacceptable reserve losses. The selection and planning of effective and economic production methods could be possible withthree-dimensional modeling, accurate determination of spatial distributions of quality parameters, and resource estimation. As a resultof this study, the present resources estimated from the geologic solid model using Netpro/Mine software was found to be 19.5 × 106m3.Modeling and 3-dimensional visualizations of resources in a scientific and rational manner with software provides mine planners withrealistic production design and planning. These models have great importance in terms of providing quick and more reliable data tomine planners and managers during decision-making processes.
