6/1/2006 - Conference papersThe Super Stopping is designed as a long-term permanent stopping for use in the main entries of the mine, while the EZ-Up Curtain Stopping, although very durable, is designed more for portability and ease of installation. This paper describes the design...

6/1/2006 - Conference papersNIOSH research suggest that by incorporating ventilation planning into the mine planning process, using propeller fans, developing new stopping materials and construction methods, and using long pillars to eliminate crosscuts where possible, the ventila...

6/1/2006 - Conference papersThis paper describes the development of reservoir models for the longwall mining environment and their application for investigating the influence of various completion design parameters on the methane drainage effectiveness of gob gas ventholes.

4/1/2005 - Conference papersA major concern in sill mat design is the loading and strengths associated with the overlying sill mat. This paper reviews past practice and present observations and measurements from over 10 mines and outlines concerns for design requirements.

6/1/2004 - Conference papersNIOSH researchers have identified a pattern of fracture zone development as an explanation for fracture formation around rectangular openings in underground mines. Two computer modeling codes were used to model different aspects of this pattern.
-
2/1/2004 - Conference papersDescribes three alternative ventilation models for use in large opening underground mines with respect to their use in mines of various levels of development.
-
8/1/2003 - Conference papersNIOSH is conducting research to develop mine design algorithms that will result in safer multiple seam mines. This paper presents an overview of multiple seam issues in the central Appalachian coalfields.
-
2/1/2003 - Conference papersIn this paper, existing ore pass design criteria rules-of-thumb using current particle flow equations are reviewed and a comparison of two computer modeling programs, Working Model (WM 2-D) and PFC2d, to simulate rock flow are investigated.
-
8/1/2002 - Conference papersThe purpose of this paper is to bring the mining community up to date with recent improvements and applications of the CMRR.
-
8/1/2001 - Conference papersThe location and time of 2,007 microseismic emissions from a limestone mine were compared with mine face development and mine layout characteristics. The occurrence of roof failure zones appears to be associated with mine plan characteristics.
