5/1/1999 - Peer reviewed journal articlesThis paper analyzes the impact of more accurate transformer models on voltages and fault currents which are realized from loadflow and fault studies of mine power systems.
-
4/1/1999 - Peer reviewed journal articlesAn evaluation of strategies for monitoring methane levels during roof bolting in an extended cut entry.
-
3/1/1999 - Peer reviewed journal articlesNIOSH researchers are investigating methods to improve safety during the transport of ore in ore passes.
-
1/1/1999 - Peer reviewed journal articlesA method is described to measure the conductor temperature of mine trailing cables during normal operation. The temperature is measured using an optical fiber located in the center of the metallic conductors.
-
12/1/1998 - Peer reviewed journal articlesThe main premise of this paper is that often the best opportunities to reduce these rates are not revealed by retrospective analysis of injury and illness data. Instead, a proactive approach is needed that accounts for risks to specific hazards that can...

2/1/1998 - Peer reviewed journal articlesThis exercise is a research tool that measures miners' proficiency in the information-gathering and decision-making skills related to escaping from a mine fire. It also helps miners to learn and practice these cognitive skills.
-
2/1/1998 - Peer reviewed journal articlesCoalbed gas content measurements are commonly used in mine safety as well as coalbed methane resource assessment and recovery applications. Gas content determination techniques generally fall into two categories: (1) direct methods which actually measu...

1/1/1998 - Peer reviewed journal articlesRoof and rib conditions were observed and assessed in 33 underground stone mines. It was found that selection of the mining horizon and mine layout decisions tremendously influence ground stability.
-
9/1/1997 - Peer reviewed journal articlesThis study describes methods of limiting cascading pillar failure, which occurs when a pillar in a mine layout fails, transferring its load to other pillars, causing failure. Design approaches are shown with examples for coal mining at shallow depth.
