Field Assessment of Control Techniques and Long-Term Dust Variability for Surface Coal Mine Rock Drills and Bulldozers9/1/1999 - Peer reviewed journal articlesAirborne respirable dust surveys were conducted at six surface coal mines to investigate the effectiveness of dust control methods used on rotary rock drills and bulldozers.
7/1/1999 - Peer reviewed journal articlesDescribes a NIOSH study of how much ventilation air reaches the end of a 40 foot box cut. Tests were run to determine how much ventilation air reaches the end of the box cut with the continuous miner at three locations in the 40-ft two-pass extended cut...
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 articlesThe Coeur d'Alene Mining District of northern Idaho is remarkable for its number of large ore bodies and for the amount of its historical production of lead, zinc and silver. Since veins were first discovered in 1884, more than 127 Mt (140 million st) o...
