Abstract In the research we examined the influence of a few geostatistical models (interpolators and kriging models) on the resource base and economic efficiency measures, on the example of coking coal deposits. The research was carried out in scenario-based mode, with 4 alternative analytic models prepared. The assessment criteria for fitted variability models based on deviations of selected ...

of actual longwall mine output in Section 7. The features of coal quality (grade) data and mining that govern the derived variability estimators are: (a) Coal mining is not selective, (b) interblock distances are large relative to semivariogram ranges, and (c) blocks are regularly shaped. To the extent

The aim of coal quality control in coal mines is to supply power plants daily with extracted raw material within certain coal quality constraints. On the example of a selected part of a lignite deposit, the problem of quality control for the run-of-mine lignite stream is discussed. The main goal is to understand potential fluctuations and deviations from production targets dependent on …

Based on the differentiation of coal ash content into constituents, the procedure is developed for estimating overall (technological and natural) dilution. The accumulated data base on the Elgin coal deposit (South Yakutia) is described. This data base was used to model coal seams for studying variability of their parameters and properties. The estimated ash contents due to mining …

ore reserves. In coal mining, they have been used to evaluate energy content, sulfur, ash, and other quality attributes of deposits. In fact, geostatistics can be used to study many properties that vary in space, but are measured at distinct locations. Research in fields as diverse as hydrology, forestry, air pollution, and global warming
South Africa's coal mining industry, which is a little more than a century old, has been based predominantly on the bord and pillar method of mining. In the late 1970's and 1980's longwall mining methods, based mainly on European practice and equipment, were introduced but for a number of reasons, including high capital cost and the geology
