10/1/2011 - Guides and manuals, Reports of InvestigationsA comprehensive guide to establish a program to curtail diesel particulate matter emissions, control pollutants after release in an underground mine environment and reduce exposures using administrative controls.
-
6/1/2011 - Guides and manuals, Reports of InvestigationsRefuge alternatives are airtight, reinforced shelters that underground coal miners can enter during a mine emergency. This publication provides recommendations for training miners in how to operate a refuge chamber.
-
5/1/2006 - Reports of InvestigationsAn underground metal mine study assessed the effects of diesel emissions control technologies (such as DPF systems, diesel oxidation catalytic converter, and biodiesel blends) on concentrations of diesel particulate matter and gases in mine air.
-
4/1/2015 - Reports of InvestigationsA report on a research study to document and develop safe practices for the use of shotcrete as ground support in underground mines, particularly in underground metal mines operating in weak host rock.
-
1/1/1993 - Reports of InvestigationsThe U.S. Bureau of Mines conducted a study to determine if commercially available automatic sprinklers could withstand the high static pressures in deep underground coal mines without leaking and if exposure to the mine environment affected their leak p...

1/1/1992 - Reports of InvestigationsThis report presents a Bureau of Mines study to identify the causes of self-heating events beneath the floor of a deep underground coal mine. The combined results led to the conclusion that pyrite oxidation was the prime cause of the heatings.
-
1/1/1989 - Reports of InvestigationsThe U.S. Bureau of Mines used a contact drilling strategy with short-collared assemblies in order to rotary drill long horizontal methane drainage holes in the Beckley coalbed near Glen Daniel, West Virginia. By decreasing the thrust and increasing the ...

1/1/1985 - Reports of InvestigationsInvestigation of coal-mine-type short-delay electric detonators to determine the delay accuracy and the probability of overlap between adjacent delay periods.
-
1/1/1985 - Reports of InvestigationsCriteria were documented for the recognition and prediction of discontinuities in advance of mining.
-
Probability of Encountering Coalbed Discontinuities During Vertical and Horizontal Borehole Drilling1/1/1982 - Reports of InvestigationsProbabilities of encountering coalbed discontinuities during vertical or horizontal drilling in a specific coalbed can be estimated based on analysis of mined-out areas of the coalbed where the size, shape, orientation, and distribution of discontinuiti...
