4/1/2003 - Technology NewsThe AHSEM computer program contains two modules to improve mine layouts for control of horizontal stress. ARBS is designed to help with selecting the proper roof bolt system from the great variety of available bolt types and patterns.

11/1/2002 - Conference papersThis study of the Chestnut Ridge Anticline found that high levels of horizontal stress are to be expected and that local geologic and topographic structures can alter the magnitude and possibly the orientation of the horizontal stress field.

8/1/2002 - Conference papersThe goal of the research described here is to develop a stress monitoring system that will provide immediate information to mine managers for making daily safety decisions as areas of poor ground are mined through.
-
7/1/2001 - Conference papersAssuring ground control safety in many mining and tunneling projects depends, at least in part, on an understanding of in situ stress conditions that will be encountered.

1/1/1997 - Peer reviewed journal articlesIn an effort aimed at monitoring mining-induced stress changes that may influence ground failure, the U.S. Bureau of Mines conducted a series of active 3-D seismic tomographic surveys at the Homestake (Lead, South Dakota) and Lucky Friday (Mullen, Idaho...

7/1/1995 - Reports of InvestigationsU.S. Bureau of Mines researchers reviewed an in situ stress estimate developed from measurements of overcore strain taken at test sites on the 7300 and 7500 levels of the Star Mine near Mullan, ID. Although the field measurements of overcoring strain we...
-
7/1/1995 - Reports of InvestigationsResearchers at the U.S. Bureau of Mines collected and analyzed overcore measurements and other indicators of in situ stress characteristics at the Lucky Friday Mine, Mullan, ID. An analysis of these data revealed that significant local variations in in ...

1/1/1993 - Reports of InvestigationsIn situ stresses are important input data for the design of safe, stable stope layouts and extraction sequences. In situ stresses were measured at the Homestake Mine, Lead, SD, using overcoring on hollow inclusion cells and borehole deformation gauges.
