New Developments On Mine Planning And Grade Control At Sishen Iron Ore Mine

Sishen Iron Ore Mine is situated 280 km north-west of Kimberley within the Northern Cape Province of South Africa. The mine produces and sells top quality iron ore of assorted specifications to numerous nationwide and worldwide purchasers. The saleable product is derived from the blending and beneficiation of differing types and qualities of hematite iron ore. This paper documents the brand new developments which had been implemented (or are in the process of being carried out) on the mine in the lengthy-time period planning, structural steel medium-term planning, grade management and materials monitoring in the beneficiation plant with particular consideration being paid to the standard of the final, saleable product. The process begins with the lengthy-time period planning where the pit shell and pit optimization is determined by Whittle 4X. New developments include the introduction of a linear programming primarily based scheduling system to reinforce the long-time period schedule generated by Whittle 4X. The LP route was selected with a purpose to take under consideration all the constraining components of the final product that could not be configured in Whittle.

To complement this the XPAC Auto Scheduler scheduling package was launched to do the medium-term mine scheduling. This 18- month rolling plan includes value parameters to allow the planner to extract an in depth operational funds from the scheduling whereas guaranteeing that manufacturing standards are maintained and grade constraints are met. The present grade management system was enhanced with GPS capabilities and a pc system to do materials monitoring. The excessive precision GPS system launched on the shovels allows for the correct management of the loading procedures on the mining face. Due to the difficult geology and grade composition of blasting blocks it is crucial to accurately differentiate between different materials in the same blasting block and being able to excavate that with the loading gear. The GPS system on the trucks allows for steel pipe correct location monitoring of dumping so as to keep observe of specific material types. The state-of-the-art material monitoring system developed for Sishen will allow the grade control officer to keep observe and report numerous parameters of the fabric from its in situ position in the blasting blocks, by way of the crusher and onto different stockpiles, in varied levels of the beneficiation course of and onto the mixing beds, into the dispatching trains and ultimately into the ships for international distribution. These developments elevate the Sishen planning and grade control programs to a brand new degree of service excellence from which management can acquire correct and timely info on product status. It also permits Sishen to maximize resource utilization whereas still complying with the tough market constraints.
