10/1/1994 - Technology NewsA method is described to increase the dust-control effectiveness of the Rotoclone dry-dust collection systems used on surface coal mine drills.
-
8/1/1994 - Technology NewsInformation was solicited from various organizations to determine the circumstances that cause power interruptions to extended cut continuous miners. The data accumulated permitted several conclusions to be drawn about why high-voltage circuit breakers ...
-
7/1/1994 - Conference papersThe paper, presents the results of roof coal thickness measurements in underground mines and rib coal thickness measurements in highwall mines. The microwave sensor described uses a unique spatial modulation scheme created by antenna motion, along with ...

4/1/1994 - Technology NewsThe objective was to develop a portable emissions measurement apparatus.
-
4/1/1994 - Technology NewsThis article describes the development of an easy-to-use, reliable, resin-grouted cable support system capable of being installed as primary and secondary roof support in coal mines.
-
1/1/1994 - NIOSH/USBM numbered publicationsA U.S. Bureau of Mines research program developed a Reduced-Exposure Mining System (REMS) that relocates personnel operating the mining machinery at the face away from the hazards to a nearby haven of relative safety.
-
8/1/1993 - Peer reviewed journal articlesThis study ranks the factors impacting survival during a coal mine fire. The authors found that a combination of actions was most effective, including installing lifelines, moderately decreasing air leakage, and decreasing the fire growth rate.
-
1/1/1993 - Reports of InvestigationsA prototype end-cab shuttle car (SC) design has been developed to improve protection and address ergonomic concerns of the SC operator in low coal mines. This report discusses research to modify a used 21SC JOY SC, retrofit the SC with the Bureau-devel...
