ABSTRACT
Modern techniques available to monitor and control open pit mining operations are analogous, in many respects, to conventional process control applications in processing plants. This paper examines current microprocessor technology used to measure, transmit, and process operating data from open pit mine production equipment. Data acquisition is performed through operator data terminals, vehicle location devices, and on-board sensors that measure payload and vital mechanical/electrical functions. Efficient and reliable data transmission from mobile equipment in a harsh environment requires an advanced radio system. General specifications of such a system are presented. Data processing of field information on a real-time basis is discussed. Current microprocessor technology is demonstrated to be a practical tool that can support mine supervision in controlling complex and dynamic mining operations. The benefits to a mine are increased productivity, better quality control, a more stable operation, and reduced operating costs. Several levels of implementation are discussed showing that mines of any size can benefit from this technology.
