  • Estimating the Unconfined Compressive Strength UCS of Emplaced Cemented Rockfill CRF from QAQC Cylinder Strengths
    Estimating the Unconfined Compressive Strength (UCS) of Emplaced Cemented Rockfill (CRF) from QA/QC Cylinder Strengths
    Armstrong J ;
    Dehn KK
    2018/02/25 | Mining Publications
    Confidence in the design and stability of an undercut cemented rockfill (CRF) span requires a thorough understanding of its emplaced material properties. The unconfined compressive strength (UCS) of cast 6×12-inch QA/QC cylinders is typically used as an index test to track the performance of a backfill plant. However, these strengths need to be adj ...

    Iannacchione, Anthony T.
    2018/02/25 | Mining Publications
    The National Institute for Occupational Safety and Health (NIOSH) has previously established pillar design guidelines for the underground stone mining industry. These guidelines were created from an empirical database of pillar observations and were largely drawn from shallow, flat-lying mining operations. Current trends forecast a great amount of ...

    Demonstrating the Financial Impact of Mining Injuries with the Safety Pays in Mining Web Application
    Heberger JR
    2018/02/25 | Mining Publications
    The Safety Pays in Mining web application, developed by the National Institute for Occupational Safety and Health (NIOSH) Mining Program, helps mines determine the potential costs associated with mining injuries. This web app groups injuries by type, either by the cause of the injury or by the nature of the injury. When the user selects one of over ...

  • Influence of Temperature on Generator Current and Magnetic Field of a Proximity Detection System
    Influence of Temperature on Generator Current and Magnetic Field of a Proximity Detection System
    Carr J ;
    Li J
    2018/02/25 | Mining Publications
    Electromagnetic based proximity detection systems (PDSs) are utilized on mining machinery to protect workers from being pinned or struck. These systems generate magnetic fields covering the space around a machine, and a miner-wearable component (MWC) detects the field. The PDS determines the distance of miners relative to the machine based on the d ...

    Evaluation of Contamination Ingress for Built-in-Place Refuge Alternatives
    Lutz T ;
    Noll J
    2018/02/25 | Mining Publications
    Mine disasters, such as fires and explosions, can create a hazardous atmosphere due to the generation of carbon monoxide (CO). After a mine disaster, contaminated mine air can enter the refuge alternative (RA) as miners enter. Most built-in-place (BIP) RAs use an air delivery system to provide an unlimited supply of breathable air through a borehol ...

  • Influence of a Continuous Mining Machine and RoofRib Mesh on Magnetic Proximity Detection Systems
    Influence of a Continuous Mining Machine and Roof/Rib Mesh on Magnetic Proximity Detection Systems
    DuCarme JH ;
    Jobes, Christopher C.
    2018/02/25 | Mining Publications
    Magnetic proximity detection systems (PDSs) are used with continuous mining machines (CMMs) to protect miners from striking and pinning accidents. Generators are used in a PDS to create magnetic fields covering the space around a CMM. The PDS determines the proximity of a miner relative to the CMM based on the magnetic flux density detected by a mi ...

    2018/02/25 | Mining Publications
    Mine monitoring through various sensors is a vital component of successful miner safety and health programs. Data from environmental, geotechnical, infrastructure, and other types of sensors are increasingly being used to discover and mitigate health and safety concerns in underground mines. In many smaller underground mines, as well as in new deve ...

    2018/02/23 | National Institute for Occupational Safety and Health (NIOSH)
    Objective: Workers exposed to dusts from concentrated animal feeding operations have a high prevalence of pulmonary diseases. These exposures lead to chronic inflammation and aberrant airway remodeling. Previous work shows that activating cAMP-dependent protein kinase (PKA) enhances airway epithelial wound repair while activating protein kinase C ( ...

    2018/02/20 | National Institute for Occupational Safety and Health (NIOSH)
    Oxidative stress generates reactive species that modify proteins, deplete antioxidant defenses, and contribute to chronic obstructive pulmonary disease (COPD) and ischemic heart disease (IHD). To determine whether protein modifications differ between COPD or IHD patients and healthy subjects, we performed untargeted analysis of adducts at the Cys34 ...
