• Evaluation of the Approach to Respirable Quartz Exposure Control in U.S. Coal Mines
  2/1/2012 - Peer reviewed journal articles
  The performance of the current regulatory approach was found to be lacking due to the use of a variable property - quartz content in airborne dust - to establish a standard for subsequent exposures.
• Field Evaluation of Air-blocking Shelf for Dust Control on Blasthole Drills
  3/1/2011 - Peer reviewed journal articles
  Field tests confirm that an air-blocking shelf installed in the inside perimeter of a blasthole drill shroud substantially improves dust control. This modification reduced respirable dust by 66%–81% in the immediate vicinity of the shroud...
• Equivalency of a Personal Dust Monitor to the Current United States Coal Mine Respirable Dust Sampler
  1/1/2008 - Peer reviewed journal articles
  The work presented in this paper focuses on the relationship between the PDM and respirable dust concentrations currently measured by a coal mine dust personal sampler unit utilizing a 10 mm Dorr Oliver nylon cyclone.
• Laboratory and Field Performance of a Continuously Measuring Personal Respirable Dust Monitor
  9/1/2006 - Reports of Investigations
  This report includes the theory of operation, description, and the performance of the Personal Dust Monitor (PDM) compared to gravimetric-based reference dust sampling methods and laboratory verification of the instruments accuracy.
• Characterization of Submicron-/Nano-scale Coal Dusts and Their Effects on Miners' Pneumoconiosis and Lung Cancer for Underground Coal Mines
  7/22/2024 - Contracts and cooperative agreements
  A contract with Pennsylvania State University to investigate the characterization of submicron-/nano-scale coal dusts and their effects on miners’ pneumoconiosis and lung cancer for underground coal mines.

• Evaluating and Developing Emerging Technologies to Improve Conveyor System Safety
  7/11/2023 - Research projects
  A project to develop interventions to reduce traumatic injuries and fatalities that occur during operation and maintenance activities on conveyors.
• Characterization of Forms of Silica with Varying Degrees of Crystallinity in Respirable Dust to Assess their Effects on Miners’ Pneumoconiosis
  7/4/2023 - Contracts and cooperative agreements
  A contract to evaluate different forms of silica embedded in the mine-emitted dusts and how they are related to their host rocks’ mineralogical and geological features. 
• Investigation of Respirable Mine Dust and Crystalline Silica Dust Characteristics and Toxicity in Metal/Nonmetal Mines
  7/4/2023 - Contracts and cooperative agreements
  A contract to investigate mine dust and respirable crystalline silica characteristics and toxicity to fill a critical knowledge gap and help ensure the health of  workers in metal and nonmetal mines.
