Abstract Hughes’ has proposed a method for dealing with the problems of interpolating coal washability data which eliminates many of the difficulties encountered in previously proposed procedures. In particular, the problem of the interpolating function becoming negative was solved, but the computational procedure proposed was not suited to convenient computation. Lyman modified the solution to provide a smoother interpolating function, recast the computations in a manner well-suited to fully-automatic operation, and generalised and further extended the method to deal with a more difficult problem relating to interpolation of bulk density, size distribution and density distributions as a function of bed depth in samples taken from a jig bed. These methods were implemented in a major project by the author. This paper presents the mathematical background to both applications and provides an example of their application to simple interpolation of washability information. The second paper of this pair provides examples of the more complex application of the method to data arising from sampling a jig bed in layers, and the third paper considers two-dimensional interpolation of washability data.
