In mining, respirable dust is a tremendous hazard for mine workers. These tiny particles can be produced in high concentrations by daily mine activities such as blasting, crushing, drilling, or transporting material. In underground coal mines, particle concentration can be a critical danger since workers are in confined spaces with limited artificial ventilation, high humidity in the air, hot temperature, and other site conditions that may lead to more complex particle identification and higher dust particle concentrations. Therefore, necessary controls should be implemented to reduce exposure and guarantee safe work environments for miners. Between respirable dust materials generated in coal mines, respirable coal mine dust (RCMD) and respirable crystalline silica (RCS) are abundant and can lead to the development of deadly lung diseases such as coal workers' pneumoconiosis (CWP), silicosis, and pulmonary massive fibrosis (PMF). Although many people in the industry have made significant efforts to research, mitigate, and control RCS and RCMD exposure, lung diseases caused by these materials remain a problem that has cost several lives. However, plenty of work can still be done to prevent dust exposure and create better working conditions for workers in the mining industry. This research aims to build infrastructure and conditions to test humidity, concentration, and dust distribution inside a chamber to provide a platform for testing new and current monitoring systems, personal protective equipment (PPE), and mitigation techniques/equipment that can help reduce the exposure of RCMD and RCS in underground coal mines. Two dust chambers were built to simulate underground coal mine conditions. A Humidity control station (HCS) was designed, constructed, and tested to supply variable humidity conditions for testing inside the chamber. Coal samples were reduced to respirable size to supply the chamber with airborne dust produced by an aerosol generator. The samples were tested with a particulate matter sensor and an aerodynamic particle sizer to determine the best internal area to place equipment inside the chamber. The detailed production procedure is covered in this document, and recommendations are made to improve the platform and for future research related to dust testing with similar conditions.

520 $a En mineria, el polvo respirable representa un gran riesgo para los trabajadores de las minas, estas particulas diminutas pueden ser producidas en altas concentraciones por actividades diarias tales como voladuras, trituracion, perforacion o transporte de material. En las minas subterraneas de carbon, la concentracion de las particulas puede ser un factor de riesgo critico ya que los trabajadores estan en espacios confinados con ventilacion artificial limitada, alta humedad en el aire, altas temperaturas y otras condiciones del sitio que pueden derivar en una mayor concentracion y complejidad para identificar particulas. Por lo tanto, se deben implementar los controles necesarios para reducir la exposicion y garantizar un ambiente de trabajo seguro para los mineros. Dentro de los materiales que se encuentran en forma de polvo respirable generados en mineria de carbon, el polvo respirable de mina de carbon (RCMD, por sus siglas en ingles) y la silice cristalina respirable (RCS, por sus siglas en ingles) son abundantes y pueden derivar en el desarrollo de enfermedades pulmonares fatales como la neumoconiosis de los mineros de carbon (CWP, por sus siglas en ingles), la silicosis y la fibrosis masiva progresiva (PMF, por sus siglas en ingles). Aunque muchas personas en la industria han hecho esfuerzos significativos para investigar, mitigar y controlar la exposicion a RCS y RCMD, las enfermedades pulmonares causadas por estos materiales siguen siendo un problema que ha acabado con demasiadas vidas. Sin embargo, mucho trabajo todavia se puede hacer para prevenir la exposicion a estos materiales y crear mejores condiciones de trabajo para los trabajadores de la industria minera. Esta investigacion apunta a construir infraestructura y condiciones para evaluar humedad, concentracion y patrones de distribucion de polvos, dentro de una camara de polvo y con esto, proporcionar una plataforma para ensayar nuevos y existentes sistemas de monitoreo, equipos de proteccion personal (PPEs, por sus siglas en ingles) y equipos/tecnicas de mitigacion que pueden ayudar a reducir la exposicion a RCMD y RCS en minas subterraneas de carbon. Dentro del alcance del proyecto, se construyeron dos camaras de polvo para simular las condiciones de una mina subterranea de carbon. Se diseno, construyo y probo una estacion de control de humedad (HCS, por sus siglas en ingles) para suministrar condiciones variables de humedad dentro de la plataforma para experimentos. Las muestras de carbon fueron reducidas a un tamano de particula respirable para introducir las particulas a la camara de polvo por medio de aerosol producido por un generador de aerosoles. Las muestras preparadas se evaluaron con un sensor de material particulado y un espectrometro de medida de tamano aerodinamico de particulas para determinar la mejor distribucion interna para ubicar equipos dentro de la camara de polvo. El procedimiento detallado de la produccion de la plataforma fue incluido a lo largo del documento, al igual que recomendaciones para mejorar la plataforma y para futuras investigaciones relacionadas con pruebas en polvos en condiciones similares.
