The Influence of Ventilation Arrangement on the Mechanism of Dust Distribution in Woxi Pithead

Abstract: Suppressing and removing mine dust from the working face is an important task for underground mines worldwide. In this paper, a numerical study was carried out to investigate the influence of ventilation arrangement on the mechanism of dust distribution. The Woxi Pithead of Hunan Chenzhou Mining Co., Ltd, China, was used as a case study, which adopted a widely used far-pressing-near-absorption (FPNA) ventilation system. Based on the theory of gas-solid two-phase flow, the program ANSYS Fluent was utilized, and… Show more

“…Due to the high energy consumption of the entire mine cooling system, it is necessary to properly design the roadway cooling system, which can ensure comfortable mining temperatures and reduce unnecessary energy consumption. To date, several mature mathematical models have been established in the field of mine ventilation, including a one-dimensional heat transfer model, a one-dimensional network flow model, three-dimensional computational fluid dynamics (CFD) models focusing on ventilation airflow [9][10][11] as well as others [12][13][14][15]. Some workers have studied the optimal design of mine ventilation through CFD simulation [16].…”
