7/1/2009 - Conference papersThis paper presents a description of geologic settings, mining conditions, rockmass characterization with geotechnical risk assessment, analysis, mapping, and control techniques used at an underground stone mine in Central Pennsylvania.
-
1/1/2000 - Conference papersThis paper outlines the evolution of the RMSS and how it can be used in a comprehensive, proactive ground control safety program. A case history describes the RMSS being used to evaluate a mechanical impact sealing machine at a limestone mine.
-
2/1/2016 - Peer reviewed journal articlesAn article about the design and testing of a new environmentally controlled primary crusher operator booth at a granite quarry near Wausau, WI.
-
2/1/2015This trade publication article by NIOSH discusses conversations researchers had with workers in the aggregates industry about silica dust exposure on the job, as well as their behaviors to avoid overexposure and their concerns regarding silicosis.
-
9/1/2011 - Brochures/flyers/pamphletsThe effect rocks and minerals have on our daily lives is not always obvious, but this book will help explain how essential they really are.
-
11/1/2008 - Peer reviewed journal articlesThis paper provides an assessment of the performance of limestone pillars as observed at 98 different locations in 34 mines in the Eastern and Midwestern regions of the United States.
-
6/1/2008 - Conference papersThe objective of the research was to cost-effectively increase the air cleaning volume and improve dust capture efficiency of an off-the-shelf dust collector with a larger motor and blower.
-
3/1/2008 - Conference papersThis paper describes a modeling approach that can be used as a tool to evaluate potential roof failure and optimize the stability of room and pillar layouts.
-
7/1/2007 - Conference papersNumerical modeling is used to evaluate the degree the pillar strength is increased with a rectangular pillar over a square pillar.
-
5/1/2007 - Conference papersA survey of roof and pillar conditions in limestone mines has revealed that bench mining of the floor between pillars can cause instability in the pillars at the perimeter of the benched area. Numerical models were used to assess those effects.
