11/1/2007 - Peer reviewed journal articlesThis paper presents a method using a ray-tracing technique to determine absorption coefficients for underground mines. Absorption coefficients are determined and presented for octave bands from 63 Hz to 8 kHz.
-
8/1/2007 - Peer reviewed journal articlesThis paper describes a simple, inexpensive, dependable, and field portable method for estimating the mass concentration of elemental carbon exiting the tailpipe of a diesel engine using a direct reading photometer in underground mines.
-
7/1/2007 - Conference papersThis paper describes some successful techniques and machine modifications that were evaluated for ergonomic considerations and are being used in productive mines to assist with roof screen installation.
-
4/1/2007 - Conference papersThis paper presents an overview of recent innovations in support technology for hard rock mining.
-
1/1/2007 - Conference papersNFPA 70E is a generally accepted industry guideline document and can be applied to mining workplaces after an analysis of the mine power system electrical arcing hazards has been completed (and Hazard/Risk Categories determined).
-
1/1/2007 - Peer reviewed journal articlesA roof-fall hazard-assessment technique was developed based on engineering judgment acquired from extensive underground stone mine experience and on examination of the literature. The technique uses observational processes to assess roof fall hazard.
-
12/1/2006 - Peer reviewed journal articlesThis paper presents the results of NIOSH research to identify state-of-the-art bulkhead designs, including design criteria, leakage monitoring systems, and emergency warning systems.
-
10/1/2006 - Technology NewsDescribes the Roof Fall Risk Index (RFRI), a method of systematically characterizing the risk of roof falls in underground limestone mines.
-
6/1/2006 - Conference papersThe ambient diesel particulate matter (DPM) concentrations (at the intakes and exhausts of the mine) was evaluated as an entire vehicle fleet of a stone mine switched from using 35% biodiesel to a water-emulsified fuel (PuriNOx).
-
6/1/2006 - Conference papersThe objective of the Diesel Emissions Evaluation Program (DEEP)-sponsored project at Inco Ltd.'s Stobie Mine was to conduct a long-term field evaluation of diesel particulate filter (DPF) systems available to the underground mining industry. Some of the...
