A Guidance Sensor for Continuous Mine Haulage
The U.S. Bureau of Labor Statistics reports that the mining industry has the highest average annual fatality rate (31.9 per 100,000 workers) among all major American industry. To address this, a major research program to reduce hazard exposure of miners with computer-assisted mining equipment was initiated by the U.S. Bureau of Mines. One application involves the manual 1 process of extracting ...
متن کاملHow Mine Simulation Contributes to Future Haulage System Developments
The past decade shows record increases in global demand for minerals and metals with an accompanying significant decline in skilled personnel. Mining companies today are examining new technologies to maximize production, reduce costs, and create safer work conditions to deal with this shortfall. Automation of an open-pit mine haulage system is receiving attention as a beneficial option since it...
متن کاملCharacteristics of Fugitive Dust Generated from Unpaved Mine Haulage Roads
Fugitive dust is generated along unpaved mine roads from intermitlent equipment traffic. Typically. the majority of such traffic consists of trucks hauling either mine product or waste from the surface mine pit andlor the processing plant. Fugitive dust generated along these unpaved mine roads includes particles of all sizes which become airborne. The potential hazards include the deleterious e...
متن کاملBBUNS: Bluetooth Beacon-Based Underground Navigation System to Support Mine Haulage Operations
A Bluetooth beacon-based underground navigation system (BBUNS) was developed to identify the optimal haul road in an underground mine, track the locations of dump trucks, and display this information on mobile devices. A three-dimensional (3-D) geographic information system (GIS) database of the haul roads in an underground mine was constructed, and the travel time for each section was calculat...
متن کاملErgonomic and Existing Seat Designs Compared on Underground Mine Haulage Vehicles
NIOSH researchers conducted a study to compare seat designs on underground coal mine haulage vehicles. The objective of the study was to support prior findings that NIOSH-designed seats, which incorporated ergonomic design features (e.g., viscoelastic foam padding and low-back support), are improved designs. Based on measured levels of vehicle jarring/jolting and perceived discomfort, researche...
