With the spike in the coal price many open cut coal mines are looking at an increase in the amount of dozer push as a strategy to increase the overall stripping cost and uncover more coal. The flexibility of bulk dozer push allows it to respond effectively to changes in the schedule.
An open cut coal mine in New South Wales requested an analysis of different mining options including direction of mining and waste dump sequencing. MEC Mining’s schedule enabled managers to plan the adjustments in the excavation and hauling fleets whilst ensuring the stability of production. Over and above that, MEC’s recommendation was subsequently used for long term strategic planning and departmental approval. This is because MEC has a wealth of experience in best practice methodology and expertise in mine planning software, crucial in evaluating various mining options in changing conditions.
MEC Mining enabled a productive open cut coal mine to optimise an existing dragline operation, thereby decreasing truck and shovel use and maintaining coal targets. The company approached MEC to provide an analysis of options that would maintain budgeted coal uncovery while maximising dragline efficiency in a key operational pit. MEC presented a diverse range of options that allowed the client to prepare for any possible scenario. MEC prepared short term designs and plans and presented key findings that enabled the client to prioritise areas of the pit.
