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.
A 1986 probability sample survey, mining industry population survey, to measure such employee characteristics as occupation; principal equipment operated; work location at the mine; present job, present company, and total mining experience.
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.
Development of a Supervisory and Management Training Program for the Underground Coal Mining Industry5/1/1983 - Contract reportsThis report describes a project in which Development of a Supervisory and Management Training Program for the Underground Coal mining Industry was developed and evaluated.
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.
1/1/1978 - Peer reviewed journal articlesExtensive analysis of mine-communications systems has identified specific areas, in particular the excessive times required to locate key personnel underground, the inadequacy of existing phone systems in terms of capacity and privacy and the inability ...
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...
