6/1/2001 - Conference papersA project to evaluate the South African bagged stone dust explosion barrier was successfully completed at the NIOSH Lake Lynn Experimental Mine.
Technology News 490 - An Inexpensive Device for Monitoring Explosions in Sealed Areas of Underground Mines6/1/2001 - Technology NewsDescription of a passive, inexpensive technique for monitoring explosion overpressures within sealed areas in underground coal mines.
5/1/2001 - Technology NewsTechniques are identified to reduce the probability of gob gas explosions.
1/1/2001 - Conference papersThis paper provides a brief overview of the ongoing study to evaluate the use of these chambers for pressure loading of full-scale seal designs using compressed air, water, or internal gas explosions.
5/1/2000 - Peer reviewed journal articlesExplosion characteristics such as the minimum explosible concentration and the rock dust inerting requirements were measured for various combustible dusts. The explosion resistance characteristics of seals was also evaluated.
5/1/2000 - Peer reviewed journal articlesProvides information on the explosibility and ignitability properties of dust clouds that can be used to improve safety in industries that generate, process, use, or transport combustible dusts.
8/1/1999 - Reports of InvestigationsNIOSH cooperated with Tecrete Industries Pty. Ltd. and BHP Australia Coal to evaluate the strength characteristics and air leakage of four seal and two stopping designs for use in underground coal mines.
6/1/1998 - Technology NewsDiscusses one type of explosion hazard that was discovered lurking inside sealed and filled plow frame sections when NIOSH investigated ignition incidents resulting from drilling into plow frames.
NIOSH Hazard ID 3 - Carbon Monoxide Poisoning and Death After the Use of Explosives in a Sewer Construction Project3/1/1998 - Hazards IDsIn a recent incident, three cases of CO poisoning in a confined space, including one fatality, were caused by CO migrating through soil after nearby use of explosives during a municipal sewer project. This incident illustrates that CO from subsurface de...
2/1/1998 - Conference papersThis paper presents data and theorem to calculate the risk of experiencing undesirable lightning related events while blasting or while engaged in other lightning sensitive activities. The paper provides an overview of lightning hazards in blasting oper...
