8/1/2003 - Conference papersThis paper describes two tools NIOSH developed. The miniature data acquisition system (MIDAS) could make geotechnical instruments in underground mines more feasible. The rock strain strip, together with MIDAS, more accurately measures rock movement.
-
6/1/2003 - Conference papersThe primary objective of the paper will be to discuss strata mechanics and ways in which the support and strata interaction can be evaluated to provide an optimized secondary support design, particularly standing support systems, for longwall tailgates.
-
2/1/2003 - Conference papersThis paper discusses roof monitoring, roof movement, the large roof fall, propagation of roof failures, and the recent support measures to stabilize the escapeway over a portion of the older limestone mine workings at the NIOSH Lake Lynn Laboratory.

8/1/2002 - Conference papersThe story of how roof bolting was implemented by the mining industry, but took so long to live up to its promise, is a fascinating example of the interaction between economics, technology, regulation, and science. It still has important lessons for today.

8/1/2002 - Conference papersA study is described with the objective of evaluating the various methods and strategies by which panels, production pillars and barrier pillars are developed and extracted under deep cover, and to develop appropriate design guidelines.

8/1/2002 - Conference papersSlope stability accidents are a leading cause of fatalities at U.S. surface mines. NIOSH is conducting research to reduce these fatalities. This paper presents some of the research and potential new technologies for slope monitoring and design.
-
8/1/2001 - Conference papersThe risk of major pillar falls can often be reduced by leaving final stumps, large enough to protect the intersection but small enough to not inhibit gob caving. Analyses were conducted to assess factors on the size variation of remnant stumps.
-
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.
-
8/1/2001 - Conference papersThe Support Technology Optimization Program (STOP) was updated to Version 2.3. This paper describes the additional features: including uncontrolled convergence into the design requirements for standing roof supports; the addition of design procedures fo...

8/1/2001 - Conference papersA historic overview of the role of mobile roof support (MRS) technologies in improving stability and worker safety is presented along with field evaluations of the MRS load rate monitoring device and other remote deformation-monitoring techniques.
