    Drawpoint control using radio frequency identification systems
    (1996) Knights, PF; Henderson, E; Daneshmend, LK
    Drawpoint control is critical in determining the cutoff point for load-haul-dump mucking operations to minimize dilution. it is also necessary to ensure even mucking distribution and to prevent possible hang-up of material within a slope. A prototype production monitoring and reporting system has been developed for load-haul-dump operations in underground mines. The system generates accurate and timely information regarding mucked tonnages and drawpoint and ore/waste pass utilization. The monitoring system integrates a PLC-based load weighing system with a radio frequency identification (RFID) system for locating the vehicle. The system records the identification and time of entry and exit of each drawpoint and ore/waste pass visited during a shift as well as the weight of each bucket load. A trial of the system was conducted at the CAN-MET Experimental Mine near Val d'Or, Quebec. The monitoring and reporting system functioned as designed, with the exception that the maximum read range of the RFID rags under dynamic conditions was found to be a limitation. RFID systems with greater range capabilities have been identified for a second generation system, The system is the first of its type in North America to demonstrate that RFID tags can be successfully applied to locate trackless underground equipment. Because of their ability to locate equipment and personnel within underground mines, RFID systems should be considered a key technology for future mine information and process control systems.

    Open systems standards for computing in the mining industry
    (CANADIAN INST MINING METALLURGY PETROLEUM, 2000) Knights, PF; Daneshmend, LK
    Key issues in managing information systems in the minerals industry will likely continue to be those relating to the integration and interoperability of disparate systems. This paper argues that, in order to harness the promised benefits of information technologies, the mining industry should adopt a set of open systems standards to define data formats and protocols for seamless data exchange. This is in direct contrast to the present situation where mining equipment, software and instrument suppliers rigidly adhere to proprietary standards for fear of losing competitive advantage. Benefits to the mining sector resulting from the adoption of such standards would be: the provision of near-time data for executive decision support and the freedom to choose best technologies. The principal benefits to the leading mining software suppliers will be increased market share as a result of "captive sites " converting to open systems standards, Examples are given of open systems standards developed for related industries such as the Petroleum Open Systems Corporation (POSC) and the Machinery information Management Open Systems Alliance (MIMOSA).
