Construction, production, and closure of any mine require cement-based building materials including ready-mix concrete, shotcrete, and various types of mine backfill. Often more than one type of material will be required at various stages, depending on the day-to-day needs. Usually, different plants, built for specific purposes, are mobilised to the mine site for specific stages, resulting each time in capital, mobilisation and de-mobilisation costs.
The authors were involved with a mine that required one such plant to enable transitioning between hydraulic fill and paste fill, based on the amount and variability of source material available, to meet the performance required. In response to the customer’s specific needs, ISL Machinery designed a multi-purpose plant with the ability to provide paste fill, hydraulic fill, shotcrete, and concrete all from the same plant setup at a relatively marginal increase in capital cost to the plant. Some of the key points to be taken into consideration in evaluating the use of a multi-purpose plant at a mine include capital availability, concrete quality and cost of production, use of low-cost waste materials, availability of production, and improved leverage relative to local aggregate and concrete suppliers. This paper outlines the innovative concept of the multi-purpose plant that allows for the flexibility in production required to produce a wide range of cement-based building materials.
