    Evaluation of Models for Interaction Probability in Autonomous Monitor and Control Environments
    Bissonette R ;
    Sbai S
    2023/06/26 | Mining Publications
    A critical component of implementing autonomous systems is the ability to use information from a robust sensory and information system to make sound, predictable, and repeatable decisions to assure safety. This means that any such system would need to evaluate what objects (people, equipment, boulders, etc.) of interest exist in that environment (w ...

    Innovative Approach for Monitoring Underground Excavations at San Xavier Underground Mine Laboratory
    Akbulut NB ;
    Anani A
    2023/06/25 | National Institute for Occupational Safety and Health (NIOSH)
    Assessing and making decisions in underground mines is crucial and is difficult due to the harsh environment and the limitation of accessibility. Monitoring plays an important role in assessing ground conditions to ensure safety and efficiency. Through consistent monitoring, a safe interoperable underground mine can be achieved, but to ensure coher ...

    2023/06/25 | Mining Publications
    This paper summarizes important findings from the ongoing National Institute for Occupational Safety and Health (NIOSH) gas well stability research. Over the past seven years, field instrumentation results from NIOSH case studies and active mine-by case studies indicate that, under shallower covers, the measured horizontal displacements within the ...

  • Developing a Velocity Model for an Underground Coal Mine Using a Compressed Load Column Seismic Source
    Developing a Velocity Model for an Underground Coal Mine Using a Compressed Load Column Seismic Source
    Boltz S ;
    Chambers D
    2023/06/25 | Mining Publications
    Induced seismicity is common in underground mining, particularly in mines that cave by design, such as longwall coal mining. Seismic monitoring is one of the few remote sensing technologies that provide an understanding of a mine's response to extraction. However, its effectiveness usually depends on understanding event locations in relation to the ...

    Investigation of Parameters Affecting Seismic Potentials in a Deep Longwall Mine
    Beale J ;
    Khademian Z
    2023/06/25 | Mining Publications
    Seismicity can be induced by rock failures or slips along geologic structures around mine workings. Depending on their intensity and proximity to the working area, seismic events may raise safety concerns in underground mining operations. However, the geological and mining parameters leading to destructive seismic events are poorly understood. Moni ...

    A Case Study of Shale Gas Well Casing Deformation in Longwall Chain Pillars Under Deep Cover
    Kim BH ;
    Su D
    2023/06/25 | Mining Publications
    Shale gas wells in longwall chain pillars are subject to longwall-induced overburden movements. Longwall mining on either side of the chain pillars can induce deformations in gas well casings. The casing deformations induced by longwall mining has raised the safety concern that casing integrity might be diminished so that intrusive shale gas could ...

    3DEC Simulations of Dynamic Direct Shear Tests Considering Joint Roughness Coefficient (JRC)
    Kim BH ;
    Larson, Mark K.
    2023/06/25 | Mining Publications
    In general, the dynamic properties, e.g., dynamic rock modulus and dynamic rock (shear or tensile) strength are two to three times greater than static moduli and strengths. Thus, understanding the dynamic rock characteristics is necessary to improve the design of support systems in underground mines, nearly all of which are subject to dynamic loadi ...

    A MEMS-Enabled Portable Gas Chromatography Injection System for Trace Analysis
    Agah M ;
    Ahn J
    2023/06/22 | National Institute for Occupational Safety and Health (NIOSH)
    Growing concerns about environmental conditions, public health, and disease diagnostics have led to the rapid development of portable sampling techniques to characterize trace-level volatile organic compounds (VOCs) from various sources. A MEMS-based micropreconcentrator (µPC) is one such approach that drastically reduces the size, weight, and powe ...
  • Healthcare Workers and Work Stress
    Healthcare Workers and Work Stress
    National Institute for Occupational Safety and Health
    June 21, 2023 | National Institute for Occupational Safety and Health (NIOSH)
    Work stress refers to the harmful physical and emotional effects when job requirements do not match workers’ resources or needs. Work stress can lead to poor mental and physical health. Mental health includes a person’s psychological, emotional, and social well-being and affects how we feel, think, and act.

  • Comparative 6 Studies of Environmentally Persistent Free Radicals on NanoSized Coal Dusts
    Comparative 6+ Studies of Environmentally Persistent Free Radicals on Nano-Sized Coal Dusts
    Azam A ;
    Bhattacharya, S.
    2023/06/20 | National Institute for Occupational Safety and Health (NIOSH)
    Coal dust is the major hazardous pollutant in the coal mining environment. Recently environmentally persistent free radicals (EPFRs) were identified as one of the key characteristics which could impart toxicity to the particulates released into the environment. The present study used Electron Paramagnetic Resonance (EPR) spectroscopy to analyze the ...
  • County Incidence and Geospatial Trends of EarlyOnset Hypertensive Disorders of Pregnancy in Kentucky 20082017
    County Incidence and Geospatial Trends of Early-Onset Hypertensive Disorders of Pregnancy in Kentucky, 2008–2017
    Browning SR ;
    Christian WJ
    2023/06/19 | National Institute for Occupational Safety and Health (NIOSH)
    Background: Early-onset hypertensive disorders of pregnancy (eHDP) are associated with more severe maternal and infant outcomes than later-onset disease. However, little has been done to evaluate population-level trends. Therefore, in this paper, we seek to address this understudied area by describing the geospatial and temporal patterns of county- ...

    Given the practically omnipresent exposures to loud sounds -wanted and unwanted- the challenge to prevent hearing loss and tinnitus remains significant. The high rate of these conditions casts doubt on the effectiveness of preventive interventions. Today we have fewer obstacles and more tools than before. Two approaches will be discussed.
