1/1/1996 - Reports of Investigations214 underground coal miners were interviewed to determine mine workers' state of fire-fighting preparedness and the technology being used to detect and respond to underground mine fires. Several important changes are suggested to deal with fires.
1/1/1994 - NIOSH/USBM numbered publicationsThis paper examines safety concerns associated with deep-cut mining, using the U.S. Mine Safety and Health Administration accident database, interviews with mine workers and operators, and conversations with state, local, and union representatives.
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.
Methane Emission from U.S. Coal Mines in 1975, A Survey : A Supplement to Information Circulars 8558 and 86591/1/1977 - Information CircularsThis Bureau of Mines report tabulates methane emissions from U.S. Bituminous coal mines with daily emission rates of at least 100,000 cfd according to states, counties, and coalbeds. Most of the methane emitted is from mines in the Appalachian States. T...
1/1/1975 - Reports of InvestigationsGeological surveys were completed in six coal mines to study the overall geology of the coalbed, and to use the resulting data to evaluate the influence of the geological characteristics of the coalbed on safe and efficient coal extraction.
Eight coal mines were visited to determine their communications usage and requirements. Volume 2 details the eight mine visits, along with the conclusions reached following each visit and the final conclusions reached.
Research and Development Contract for Coal Mine Communication System: Volume 1 - Summary and Results of System StudyEight coal mines were visited to determine their communications usage and requirements. Volume 1 summarizes the entire report and includes both a dissertation on the strengths and weaknesses of various available communication techniques and a set of re...
Research and Development Contract for Coal Mine Communication System: Volume 3 - Theoretical Data BaseEight coal mines were visited to determine their communications usage and requirements. Available equipment was surveyed and evaluated to determine its applicability to the needs of the mines. Volume 3 contains all information used in predicting the per...
Research and Development Contract for Coal Mine Communication System: Volume 4 - Environmental MeasurementsEight coal mines were visited to determine their communications usage and requirements. Volume 4 describes the propagation measurements made in selected mines during the project, along with findings resulting from these measurements.
1/1/1974 - Information CircularsThis Bureau of Mines survey of methane emissions indicates that total daily emissions have declined from 227 mm ft3 in 1971 to 214.7 mm ft3 in 1973. The highest average daily emissions in million cubic feet per day are detailed by state.
