Investigation of Coal Dust Remediation using a Surfactant in an Aqueous Solution
… and popular means of combating respirable dust in an underground coal mine. Due to a noticeable increase in black lung among coal miners and new dust regulations, surfactants or wetting agents have been used to aid in dust suppression. The surfactant facilitates the wetting process by …

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 …

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 …

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 …
