NIOSH Mining Program page on blasting and explosives.
10/11/2014 - Contracts and cooperative agreementsA contract to provide miners with real-time alerts to potentially harmful air contaminants if a dangerous threshold of either immediate or timed exposure is detected.
3/1/2013 - Reports of InvestigationsThis report presents a new concept in perimeter control blasting for underground mine drifting applications focusing on the importance of the buffer holes in a blast design.
5/1/2011 - Peer reviewed journal articlesPeak particle velocity (PPV) and distance measurements from a single-charge blast test conducted by Swedish researchers in iron ore at the Kiruna Mine in northern Sweden are presented.
3/1/2010 - Conference papersThe authors' goal is to summarize the totality of the USBM's explosives and blasting research.
High Resolution Seismic Refraction Tomography for Determining Depth of Blast Induced Damage in a Mine Wall8/1/2009 - Peer reviewed journal articlesHigh resolution seismic refraction tomography has proved to be a useful tool to effectively estimate depth of blast induced damage in a mine face.
A Hydrodynamics-Based Approach for Predicting the Blast Damage Zone in Drifting as Demonstrated Using Concrete Block Data8/1/2009 - Peer reviewed journal articlesThis paper presents a blast design technique based on a hydrodynamic method and introduces modifications to account for different explosives from those used in a calibration test.
1/1/2008 - Conference papersNIOSH researchers collected basic data from two blast rounds at the SSX-Steer Mine as a component of a larger study on controlled blasting, the goal of which is to reduce injuries from falling rocks in underground mines.
1/1/2008 - Conference papersThis paper presents a modification which corrects the mathematical error in the Holmberg-Persson approach to perimeter blast design.
1/1/2007 - Conference papersThis paper reviews the potential hazards from toxic fumes produced by detonating explosives in surface mining and construction operations. Techniques to protect workers and the public from the hazards of explosive-related toxic fumes are discussed.
