Investigation on the dust migration behavior and safety zone in the fully mechanized mining face

Environmental Science and Pollution Research, 2021
High dust concentration produced in the fully mechanized longwall mining face is a significant threat to the front-line workers. It is critical to discover the potential safety zone to ensure routine personnel operation. Fluent 2020 R1 is employed to reappear the spatial dust distribution based on the gas-solid coupling theory.
