The Problem The Problem –– Coal Mining Supply Coal Mining Supply Chain Chain
• No mechanism for exchange of data about Coal• Systems require translation tools and data factories
From Boreholes to Bottom Line
The Problem The Problem –– Coal Mining Supply Coal Mining Supply Chain Chain
Historically no standard for data definitionRecorded values can be ambiguous eg. Coal ash content can vary depending on state, processes it has undergone‘Air dried’ or ‘Dry, ash free’Apples with apples – context for measured values

Runge’s Response to the ProblemRunge’s Response to the Problem
Runge submitted a proposal to ACARP to “develop a standard for the interchange of
data in the coal mining value chain”Grant awarded in Summer 2003.
