5/17/2018 - Peer reviewed journal articlesA study using computational fluid dynamics (CFD) models to examine the effects of air-blocking shelves on airflows and respirable dust distribution associated with medium-sized surface blasthole drill shrouds as part of a dry dust collector system.
-
2/1/2015 - Peer reviewed journal articlesA paper detailing the use of a bit sleeve in combination with a dusthog-type bit to improve dust extraction during the critical initial phase of drilling.
-
1/1/2012 - Peer reviewed journal articlesThis paper documents the evolution of the bit isolator and chuck isolator. Laboratory testing confirms that production bit and chuck isolators reduce the A-weighted sound level generated during drilling by 3.7 to 6.6 dB.

7/1/2010 - Peer reviewed journal articlesThe aims of this research were to determine the effectiveness of arbitrary shape coding in reducing selection error rates in a virtual analogy of roof-bolting and whether any advantages exist for mirror or place layouts for dual control situations.

Summary of NIOSH Research Completed on Dust Control Methods for the Surface and Underground Drilling12/1/2008 - Peer reviewed journal articlesThis paper summarizes the results of research that has been done on respirable dust control for surface mine blasthole drilling operations.
-
9/1/2007 - Peer reviewed journal articlesTests have been conducted by NIOSH on a newly designed device for smaller diameter drills that separates the water from the bailing air before it reaches the bit and thus provides the cost benefit of dry drilling while providing the benefit of wet drill...

1/1/2006 - Peer reviewed journal articlesNIOSH initiated a study of a roof bolter to reduce noise exposure to mine roof bolter operators. When drilling into granite, it was found that wet drilling generated lower sound power levels and performed better than vacuum drilling.
-
7/1/2001 - Peer reviewed journal articlesA number of ignition incidents involving mining and farm equipment have illustrated the surprising danger of drilling, cutting, or otherwise penetrating sealed compartments or frames that are filled with metal scrap for ballast.
