8/1/2004 - Conference papersThis article discusses highwall stability, reasons for early pull out of highwall miner holes, and geotechnical engineering and planning factors, as well as operating practices to improve highwall stability and minimize the risk of a trapped miner.
-
6/1/2004 - Conference papersThe point estimation method for the probability of sliding is efficient and expedites slope stability simulation routines in NIOSH software to stochastically describe rock slope behavior and assist engineers in catch bench design for large slopes.
-
5/1/2004 - Conference papersA case study is presented that relates statistical descriptions of joint sets to the distribution of local wedge failures along the crest of a catch bench at the Yellowstone Talc Mine.
-
3/1/2004 - Reports of InvestigationsHighly stressed rock in stopes continues to be a primary safety risk for miners in underground mines because this condition can result in failures of ground that lead to both injuries and death.
-
8/1/2003 - Peer reviewed journal articlesLaser-based instruments are used in areas where coal dust ignition presents a safety hazard. This NIOSH study determines when an optical beam may be considered a potential ignition source in underground coal mines or coal storage facilities.
-
8/1/2003 - Conference papersThe advance-and-relieve method benefits from lateral destressing. Numerical modeling proved useful in studying the basic mechanics of lateral relief while investigating the sensitivity of results to different parameters using controlled experiments.
-
8/1/2001 - Conference papersThis paper introduces warning signs of slope instability so operators are better able to recognize hazards. The most common slope monitoring equipment and practical methods of installation are discussed as well as the limitations of these systems.
-
2/1/2001 - Conference papersEvaluation of the "Advance and Relieve" mining method is described to determine effectiveness for conditions where high horizontal stresses caused long running roof falls resulting in hazardous conditions and the premature abandonment of panels.
-
8/1/2000 - Conference papersTo determine causes of slope failure and highwall/spoilbank failure, this study reviews accident statistics, surface mining laws, the relevant literature, and observations from mine visits. The study emphasizes surface mines in WV, OH, and PA.
-
7/1/2000 - Reports of InvestigationsShort-dumping rather than edge-dumping might reduce dumping-related accidents, but many operators believe it is less cost effective. To evaluate this perception, NIOSH reviewed the costs of various dumping methods at waste and spoil piles.
