About
This article summarizes a NIOSH project to develop a portable field-use testing system for conducting ASTM-1550-05 round determinate panel tests. The test system can be used at the mine site to obtain shotcrete toughness strengths that are required for determining the support requirements for mine openings, minimizing falls of ground, and reducing mine roof-fall incidents.
