    2022/06/30 | National Institute for Occupational Safety and Health (NIOSH)
    Although advanced technologies (i.e., artificial intelligence [AI], robots) are often discussed as drivers of societal inequality, our research examines whether people living in more unequal societies tend to view technology as a greater threat to jobs in general. Building from research that societal inequality heightens concerns about status hiera ...

    In utero air pollution exposure has been associated with adverse birth outcomes, yet effects of air pollutants on regulatory mechanisms in fetal growth and critical windows of vulnerability during pregnancy are not well understood. There is evidence that epigenetic alterations may contribute to these effects. DNA methylation (DNAm) based age estima ...

    A retrospective study on accident analysis of the United States mines for 36 years was achieved using statistical analysis on the MSHA's accident databases between 1983 and 2018. A regression model of generalized estimation equation (GEE) was used for unbalanced panel data that provided 95,812 observations for 19,924 mine-ID-year in aggregate, coal ...

    2022/06/26 | Mining Publications
    Shale gas wells in longwall abutment pillars are subjected to longwall-induced ground movements, and their stability has been a safety concern for both the mining and gas industries. To understand the impact of longwall mining on the stability of gas wells in longwall abutment pillars, a test well was drilled in a longwall pillar between two adjace ...

    2022/06/26 | Mining Publications
    Conventional triaxial tests evaluate rock strength using a load path where the minimum principal stress is held constant and the maximum principal stress is increased monotonically until the peak strength is achieved. Although brittle rock mechanical behavior is relatively well-understood under this loading path, in many practical rock mechanics ap ...

    2022/06/26 | Mining Publications
    In the Northern Appalachian Basin of the United States, most of the production wells in shale gas reservoirs intersect with a bedded sequence of minable coal layers. The gas wells are often positioned in the coal mine abutment pillars for protection, but longwall-induced stresses may lead to excessive deformation in the gas well casing and potentia ...

    In this study, 3DEC modeling in conjunction with the Discrete Fracture Networks (DFNs) technique was performed to better understand the behavior of shearing faults in a relatively large-scale direct shear test model. The DFNs explicitly generated two different geometries of the fault plane surface indicating the stepped or smooth waviness of the su ...
