8/1/2004 - Conference papersThis paper focuses on a computer simulation used to model roof behavior and rock bolt interaction in a collaborative study of ground behavior, reinforcement performance, and stress redistribution in a coal mine entry under severe horizontal stress.
-
2/1/2004 - Conference papersThe primary goal of this project was to obtain detailed data on the interaction between the mine roof and the support elements for use in modeling studies.
-
8/1/2003 - Conference papersThis paper describes a study where the variations of the magnitude of the horizon stresses in sedimentary deposits in the eastern and Midwestern U.S. are examined with respect to two factors, the elastic modulus of the rock and the site depth.
-
8/1/2003 - Conference papersThe advance-and-relieve method benefits from lateral destressing. Numerical modeling proved useful in studying the basic mechanics of lateral relief while investigating the sensitivity of results to different parameters using controlled experiments.
-
2/1/2001 - Conference papersEvaluation of the "Advance and Relieve" mining method is described to determine effectiveness for conditions where high horizontal stresses caused long running roof falls resulting in hazardous conditions and the premature abandonment of panels.
-
1/1/2000 - Conference papersThe practical application of the "advance and relieve" method is discussed. A trial of the method was conducted for a room and pillar coal operation that was experiencing roof cutters and long running roof falls caused by high horizontal stresses.
-
8/1/1998 - Conference papersA design technique is presented which provides stone miners with a method for making stability assessments. The consequences of widening rooms, changing geology and horizontal stresses, and different rock bolts on roof beam failure are discussed.
-
7/1/2008 - Conference papersThis paper explores the relationships between deep-seated and shallow in situ stresses in several of the world’s coalfields, using a data base of more than 350 stress measurements from underground coal mines.
-
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.
-
8/1/2005 - Conference papersThis research seeks to provide design guidelines that enable mine planning engineers to assess the safety risk of an adverse multiple seam mining interaction based on mine geometry factors, mine layout factors, and site specific geologic conditions.
