2/1/2009 - Conference papersEach of the electronic versions of the MSHA fatality reports since 1995 was analyzed in detail, categorized by the type of the ground fall hazard. The remainder of the paper is devoted to evaluating each of the five largest categories.
-
7/1/2008 - Conference papersThe centerpiece of this project is development of a Dynamic Failure Control Program to monitor evolution of dynamic failure hazards with changing geologic conditions to assure that control and protective measures are appropriately deployed.
-
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 papersThis paper reviews 11 prevention control techniques for coal mine bursts.
-
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.
-
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.
-
6/1/2008 - Conference papersThis work attempts to provide rock mechanic tools that will enable a mine operator to make economic decisions that will also ensure a safe working environment.
-
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.
