• Review of Recent Research on Organizational and Behavioral Factors Associated With Mine Safety
  1/1/1989 - Information Circulars
  This 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.
• Characterization of the 1986 Metal and Nonmetal Mining Workforce
  1/1/1988 - Data and statistics, Information Circulars
  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.
• A Short-Range Locator System for Detecting Trapped Miners
  1/1/1984 - Reports of Investigations
  A 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.
