Application of Radio-Frequency Identification Systems to Collision Avoidance in Metal/Nonmetal Mines1/1/2001 - Peer reviewed journal articlesNew developments in radio frequency identification (RFID) systems show promise for reducing the number of collisions in mines. This paper describes tests conducted on off-the-shelf RFID systems and the subsequent development of a custom RFID system.
11/1/1995 - Reports of InvestigationsLaboratory and field testing results are presented for reducing dust and/or gas ignitions associated with blasting operations in oil shale and sulfide ore mining applications.
1/1/1992 - Information CircularsA U.S. Bureau of Mines review of all upper extremity cumulative trauma disorder injuries as reported by law and maintained on the MSHA accident data base from 1985 thru 1989.
Propagation of EM Signals in Underground Metal/Non-Metal Mines: Magma Copper Company - San Manuel Mine4/1/1981 - Contract reportsThis report presents test results, data evaluations, and typical system performance expectations based on wireless electromagnetic propagation measurements performed in the MAGMA Copper Company San Manuel mine near Tucson, Arizona during March 30 throug...
The Implementation of UHF Radio Communications and CCTV Monitoring Systems in a Room and Pillar Metal/Non-metal Mine3/1/1981 - Contract reportsThis report describes the design and implementation of UHF radio and closed-circuit television systems in the Black River room and pillar limestone mine near Butler, Pendleton County, Kentucky.
1/1/1981 - Contract reportsThis report describes the results of a measurement and analysis program to characterize wireless radio transmission in metal-nonmetal mines over a wide frequency range from 0.2 to 1,000 mhz and over a variety of mine environments.
This study addresses several engineering and economic facets of possible roll-over protective structure (ROPS) and falling object protection structure (FOPS) requirements in the metal-nonmetal mining industry.
