Abstract
Where rock dumps are created in many open cut mining operations, Serious pollution problems may be created due to oxidation of sulphide components. The resulting acids and acidic compounds may be released into rivers and streams with Serious on sequences for the environment. Knowledge as to the rate at which these substances are formed and the location within the dump where oxidisation is occurring are important factors in devising optimal strategies for managing the waste site. The oxidisation process generates heat. From temperature recordings taken in boreholes through the rock dump over a period of time, it is expected that both the strength and position of the thermal source may be determined. For this preliminary study it is assumed that one spatial dimension will be sufficient to evaluate the effectiveness of the inverse solution procedure adopted. In determining the internal heat sources it is necessary to allow for heating of the rock dump from the seasonably varying conditions.
