7/1/2010 - Conference papersInstrumented test sites were installed in the tailgates of two western longwall operations; results of the support performance and ground reaction are presented in terms of developed support loads and displacements and tailgate entry convergence.
-
1/1/2010 - Conference papersThis paper describes the impact of ground control research by the Bureau of Mines and NIOSH on the safety of underground coal miners.
-
7/1/2009 - Conference papersThis study extends the method of dynamic analysis to events driven by slip on geologic features.
-
7/1/2009 - Conference papersThis paper provides an overview of current deep cover pillar recovery practice.
-
7/1/2009 - Conference papersAs part of an effort to obtain more field data on longwall tailgate and support interaction, a study was conducted at a longwall mine in the Herrin No. 6 coal seam in southern Illinois.
-
7/1/2008 - Conference papersThis paper presents a pillar design methodology that was developed from a study of pillar performance in operating stone mines and concludes with guidelines for applying a developed equation and selecting appropriate input parameters.
-
7/1/2008 - Conference papersIn this NIOSH study to optimize standing roof support design, ground response curves were developed for longwall tailgate conditions from numerical models of Pittsburgh Coal Seam geology.
-
6/1/2008 - Conference papersThis paper compares the transverse load capabilities of several block materials and wall dimensions commonly used in stopping constructions based upon simulated three-hinge, rigid-arch loading tests of half-wall constructions.
-
3/1/2008 - Conference papersSome surprising results were revealed in this study designed and implemented by NIOSH to evaluate the effectiveness of pre-driven longwall recovery rooms supported with pumpable concrete roof supports.
-
7/1/2007 - Conference papersAn intelligent drilling system has been developed that can complement scoping and core analysis to provide a more complete picture of roof strata and is capable of seeing features or conditions that are not always obvious in more traditional methods.
