  • Ventilation Research Findings for Enhanced Worker Safety When Mining Near Unconventional Gas Wells in Longwall Abutment Pillars
    Ventilation Research Findings for Enhanced Worker Safety When Mining Near Unconventional Gas Wells in Longwall Abutment Pillars
    Addis JD ;
    Ajayi KM
    2023/09/19 | Mining Publications
    Unconventional gas wells continue to be drilled through current and future coal reserves in Pennsylvania, West Virginia, and Ohio. The ability for both mining and gas producing activities to coexist safely is a continuing question for federal and state regulatory entities as well as for industry representatives. A hypothetical, gas well casing fail ...

  • Effects of Vertical AirBlocking Ring of Drill Shroud on Dust Control for Surface Mine Drilling Operation Using CFD
    Effects of Vertical Air-Blocking Ring of Drill Shroud on Dust Control for Surface Mine Drilling Operation Using CFD
    Potts, J. Drew ;
    Reed, William R.
    2023/09/19 | Mining Publications
    Dust control by a horizontal air-blocking shelf inside a drill shroud was effective in a previous study by researchers at the National Institute for Occupational Safety and Health (NIOSH). However, when a medium-sized drilling machine lowers its mast, material deposited on the shelf can produce a significant dust cloud. To minimize this dust exposu ...

    2023/09/19 | Mining Publications
    A stable and well-maintained mine ventilation system is the key to ensuring a safe and healthy working environment for miners. A sudden, unplanned, and significant change in airflow termed as abnormal airflow is frequently observed in mine ventilation. Some abnormal airflows can return to normal without manual intervention; however, some abnormal a ...

    Analysis of Variation in Longwall-Induced Permeability Under Different Mining Depths
    Addis JD ;
    Ajayi KM
    2023/09/19 | Mining Publications
    Longwall-induced deformation could compromise the stability of shale gas wells positioned in the abutment pillars of current and future coal reserves. Consequently, gas from the casing(s) could flow towards the mine increasing the risk of explosive gas accumulation beyond the mandated limits. To assess the impact of this hypothetical scenario, the ...

    2023/09/19 | Mining Publications
    Lithium-ion (Li-ion) batteries are finding more use as power sources in the mining industry. However, they are known to pose significant fire and explosion hazards. When a Li-ion battery is exposed to excessive operating conditions, its internal temperature may exceed a normal operating range, allowing the active component materials to decompose or ...

  • A Review of Pulmonary Neutrophilia and Insights into the Key Role of Neutrophils in ParticleInduced Pathogenesis in the Lung from Animal Studies of Lunar Dusts and Other Poorly Soluble Dust Particles
    A Review of Pulmonary Neutrophilia and Insights into the Key Role of Neutrophils in Particle-Induced Pathogenesis in the Lung from Animal Studies of Lunar Dusts and Other Poorly Soluble Dust Particles
    Castranova, Vincent ;
    Crucian B
    2023/09/14 | National Institute for Occupational Safety and Health (NIOSH)
    The mechanisms of particle-induced pathogenesis in the lung remain poorly understood. Neutrophilic inflammation and oxidative stress in the lung are hallmarks of toxicity. Some investigators have postulated that oxidative stress from particle surface reactive oxygen species (psROS) on the dust produces the toxicopathology in the lungs of dust-expos ...
