Polarized Light Microscopy and Image Processing as a Near Real-time Monitoring Tool for Coal Mine Dust Monitoring
Airborne dust in coal mining environments presents a persistent occupational health hazard, with complex and heterogeneous particle compositions that complicate exposure assessment. Despite regulatory advancements, the reemergence of severe lung diseases has underscored the limitations of …

Monitoring and Control of Coal Dust Exposure Using Low-Cost PM Sensors and Computational Fluid Dynamics
<p>"Overexposure to respirable coal mine dust has been linked to causing serious health problems including coal workers pneumoconiosis (CWP) and chronic massive fibrosis. The prevalence of these health problems has been on the increase since the 2000s due to increased exposure levels with roof …

Anthropogenic landscapes : Owens Lake, CA
… new infrastructure of pipes, roads, sensors, and dust monitoring equipment was overlaid. Each cell was re-tilled, re-watered, re-planted, or re-paved, resulting in a strange yet fascinating ecology where multiple "natures" (wild, artificial, and reconstructed) co-exist uncannily. As state-owned …

Application of a TGA Method to Estimate Coal, Carbonate, and Non-carbonate Mineral Fractions as a Proxy for the Major Sources of Respirable Coal Mine Dust
Inhalation of respirable dust in coal mines is a serious occupational health hazard which can lead to the development of chronic and irreversible lung diseases, such as Coal Worker's Pneumoconiosis (CWP) and Progressive Massive fibrosis (PMF). After the passage of the Federal Coal Mine Health and …

MEMS Hybrid Electronic Integration: From Micro-Robotic Actuation to Control and Monitoring of MEMS Sensor
… metal. The second project addresses the need for monitoring respirable particulate matter (PM) smaller than 4 μm, which can remain suspended in air for extended periods and is prevalent in environments such as coal mines and diesel exhaust. These particles are linked to respiratory illnesses, …

Investigating the Effects of Particle Loading and Agglomeration on Respirable Coal Mine Dust Particle Classification by SEM-EDX
Respirable coal mine dust (RCMD) still poses serious occupational health hazards to coal miners and can lead to incurable lung diseases such as coal workers' pneumoconiosis (CWP, also referred to as "black lung"). Further, CWP can develop into a more severe form known as progressive massive …

Rapid FTIR analysis for respirable crystalline silica monitoring in coal mines using readily available sampling equipment
… workers can be exposed to respirable coal mine dust (RCMD) in conjunction with respirable crystalline silica (RCS). Overexposure can pose serious health risks, including development of coal workers' pneumoconiosis (CWP) (also known as "black lung"). CWP has the potential to progress to a more …

Demonstration of Optical Microscopy and Image Processing to Classify Respirable Coal Mine Dust Particles
Inhalation of respirable coal mine dust (RCMD) can lead to chronic lung diseases, including coal worker’s pneumoconiosis (CWP) and more severe forms such as progressive massive fibrosis. After the Federal Coal Mine Health and Safety Act was passed in 1969, limits on exposure to respirable dust were …

Toward Rapid Silica Analysis of CPDM Samples using Portable Fourier Transform Infrared Spectrometry
Continuous personal dust monitors (CPDMs) are widely used to monitor respirable coal mine dust (RCMD) to reduce miners' exposures, but they are unable to directly assess respirable crystalline silica (RCS) concentrations, which are linked to the recent rise of respiratory diseases among coal …
