The Smart Marker System-a new tool for measuring underground orebody low in Mock and sublevel mines

摘要

In the past, measurement of ore flow in block and sublevel caves has been performed with passive 'markers' (often made from steel pipes) embedded into the orebody. Extracting passive markers along with the ore is labour intensive and often requires many years of commitment. The Smart Marker system uses hardened Radio Frequency Identification (RFID) technology to automate the marker detection process, allowing the measurement and analysis of underground ore movement to be carried out without affecting production draw rates.
