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.
-
6/1/2006 - Conference papersA new protocol based on rigid arch loading of the structure is proposed to determine the true transverse load capacity of block stoppings. Tests show that load capability depends on the block's physical properties and the wall's geometric properties.

6/1/2006 - Conference papersNIOSH research suggest that by incorporating ventilation planning into the mine planning process, using propeller fans, developing new stopping materials and construction methods, and using long pillars to eliminate crosscuts where possible, the ventila...

10/1/2002 - Conference papersOverview of a variety of techniques and methods that can be used to improve the air quality in underground stone mines.
-
8/1/2001 - Conference papersThis paper presents investigations of underground measurements conducted to determine the loading response of stoppings constructed from lightweight aggregate concrete masonry units.
