Title

Mathematical Modelling of the Coal Instantaneous Ash vs. . . Density Curve

Abstract

The advancement of computer applications in the coal industry is focusing interest on the presentation of washability data by mathematical functions. The normal method of presenting washability data is in the form of five curves, usually fitted by eye or by cubic spline functions. It has been shown that coal washability can be characterized by two basic relations: the instantaneous ash vs relative density relationship and the instantaneous yield vs relative density relationship. In a new approach to the mathematical modelling of the instantaneous ash vs relative density relationship, the application of the algorithm to a data set from a mine in central Queensland was successful.
