Dragline and drill production monitors

This paper outlines the process of improvement utilizing performance monitors and GPS systems on an opencast strip mine. Its primary focus is to maximize coal exposure by draglines and secondly to improve on those processes impacting directly on the dragline operation. The Aquila (DM2/5 system) navigation and monitoring systems were installed on the overburden drills. Their main function is to eliminate manual staking and positioning thereby ensuring a regular pattern being drilled. Holes drilled to planned depth reduce drill metres and it minimizes coal losses and contamination at the coal interfaces. The CAES (Computer Aided Electronic System) will be installed and evaluated on the Caterpillar D11 dozers at Optimum. This system ensures a correct dragline pad elevation through the use of planned elevations and GPS technology to achieve the optimal pad elevations for draglines consistently. The draglines are equipped with a Dragline & Operators Performance Monitor. This monitor allows the operator to control his own performance. It reports on all productivity, method and poor operating techniques. These monitoring systems send critical operational information back to the office. This source data resides in central databases from where it is converted and integrated into management information. To manage an operation means that you as a manager must be able to set objectives and targets and to achieve your goals the activities involved must be measurable.
