1/1/1989 - Information CircularsThis report presents a literature review conducted by the U.S. Bureau of Mines summarizing what has been learned from recent empirical studies of the relationship between mine safety and the characteristics of miners, mine management, and mining companies.
1/1/1984 - Reports of InvestigationsA short-range locator system capable of locating trapped miners has been devised. The system consists of a light-weight, low-power radio transmitter incorporated into a miners cap lamp battery and a directional receiver carried by rescuers.
7/1/1980 - Conference papersField studies have been conducted in a large number of coal mines throughout the U.S. to determine the effectiveness of electromagnetic techniques in locating men trapped underground following a mine disaster.
Analytical Investigations of Electromagnetic Location Schemes Relevant to Mine Rescue: Part I - Executive Summary; Part II - Collected Reprints - Analytical Investigations of Electromagnetic Location Schemes Relevant to Mine Rescue12/2/1974 - Contract reportsA summary of past analyses that are relevant to electromagnetic location in mine rescue situations. The analytical results indicated that detection of a trapped miner equipped with a special transmitter is feasible in most situations.
7/14/1974 - Contract reportsThis report describes a circuit for driving a low-frequency loop antenna from a miners cap lamp battery. The circuit is a miniature waveform generator and is part of the electromagnetic (em) trapped miner location system. Two engineering models were des...
