Scale And Numerical Modeling To Determine Operating Points Of A Non-Clogging Vortecone Filter In Mining Operation, Ashish R. Kumar, Sampurna Arya, Adam Levy, Steven Schafrik, William C. Wedding, Kozo Saito
Progress in Scale Modeling, an International Journal
Numerical and scale modeling studies of Vortecone, a pressure-driven wet-scrubber device for the efficient capture of over-sprayed paint in the automobile industry, are presented. In this manuscript, Vortecone was tested for removing dust particles from underground mining operations. The pressures required to operate Vortecone and the airflow rates through the Vortecone are the two most important factors for mine ventilation systems. This study used dry, no-particle conditions to obtain relationship between these two parameters and then designed a Vortecone filter ventilation system for mining operations. Commercial software, SC/Flow, was used to generate the CFD model with unstructured meshes and a …

Progress in Scale Modeling, an International Journal
Meeting federal dust standards at a longwall mine face is among the more difficult challenges for a longwall mine operator. With recent changes in federal dust regulations requiring lower worker exposure, maintaining compliance has become increasingly difficult. The authors recommend the concept of controlling respirable and float dust, which is inherent in longwall mining, through the application of a flooded-bed dust scrubber to a longwall shearer. A full-scale physical model of a longwall shearer, modified with an integrated flooded-bed scrubber, was designed and fabricated at the University of Kentucky to measure the effects of a flooded-bed scrubber on dust capture …
