Abstract/Summary Coal fragmentation is a function of coal type and mining process. Each unit step in the mining, handling and crushing chain of coal imparts energy to the material and impacts on size degradation and consequent mineral matter liberation and plant yields. The ability to predict, monitor and optimise this process would enhance plant design and operation, production, and hence, profitability. An empirical study of coal breakage was able to establish a relationship between coal material strength (as a function of coal type and rank), unit block size distribution (as a function of coal lithotype/stone band thickness and cleat spacing), comminution energy (using single particle impact breakage) and the size distribution of resulting daughter particles for a given top size. This relationship was used to successfully develop simulations of coal breakage behaviour in unit processes such as blasting and crushing. The challenge was to integrate these models to provide a capability for tracking fragmentation from the pit face to plant feed, and to test this capability by field trials.
