7/1/2008 - Conference papersThis study examines the use of a commercially-available lubricant for hearing aids to determine whether it would facilitate improved fit and attenuation for earplugs.
-
7/1/2008 - Conference papersThis paper describes the results of different chain types and configurations installed on a continuous mining machine conveyor system and the resulting sound power levels.
-
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.
-
7/1/2008 - Conference papersThis paper examines catastrophic failures of evaporite mines (including salt, potash and trona) that show that violent failure does, in fact, occur and attempts to identify common factors and characterize the mechanism of failure.
-
7/1/2008 - Conference papersThis paper provides detailed information on the findings of NIOSH research measuring the sound power level generated by a horizontal vibrating screen with the screen either directly on the floor or on rubber isolation pads.
-
7/1/2008 - Conference papersThis paper presents the results of a NIOSH study to evaluate UCS changes occurring in a broad range of weak coal measure rocks over a one-year time span.
-
6/1/2008 - Conference papersThis paper presents the results of a NIOSH parametric study that quantifies the impact of various deformable materials in block stopping construction under transverse load conditions.
-
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 paper summarizes the modeling efforts conducted by NIOSH in the U.S. and CSIRO in Australia to address various gas management issues encountered in longwall mines using the application of computational fluid dynamics (CFD) and numerical reservoir m...
-
6/1/2008 - Conference papersThis NIOSH study was conducted to establish the effects of a diesel particulate filter (DPF) system with sintered metal substrate on the concentrations and size distributions of nano and ultrafine aerosols and concentrations of nitric oxides in undergro...
