In recent years there has been a major change among mining companies in their mining methods. This has been driven by the need to increase shareholder value and optimising the value from an operation. With this understanding there has been a need for all producers to become more efficient in their mining processes. An analysis of the coal losses at Mount Thorley Operations indicated that the major losses were in the dragline section of the mine due to coal damage from throw blasting. This damage was evident after the removal of the overburden by the dragline.Coal and Allied Mount Thorley Mine in partnership with Orica Explosives developed a process to reduce the coal loss associated with the throw blasting of Mt Thorley. Orica provided its specialised knowledge and experience in the drilling and blasting area and combined this with the local mining knowledge and expertise of Mount Thorley Operations personnel to conduct the project. This partnership reduced coal loss in excess of 50 per cent whilst maintaining targeted dragline productivity.
