coal quality models. Vulcan has tools to quickly and easily generate the many grids involved in coal quality modelling and the grid calc menus allow advanced manipulation of the data and calculations between grids. scripts make complex and repetitive tasks easy, repeatable and auditable. 04 Minor seams may not have enough data to
naturally occurring deposits in such forms and amounts that economic extraction is currently or potentially feasible (Wood et al., 1983). 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., 1983).

The float-sink test is a commonly used technology for the study of coal washability, which determines optimal separation density for coal washing based on the desired sulfur and ash yield of the cleaned coal. In this study, the float-sink test is adopted for a high-sulfur Late Permian coal from Hongfa coalmine (No.26), southwestern Guizhou, China, to investigate its washability, and to analyze ...
If the purpose of the calculation is to obtain a general estimate for the tonnage of coal on a property or a regional average resource estimate, site-specific information (the details of coal composition) are not needed and an average coal density is commonly used for the calculation. Relative coal density is measured as specific gravity.
