TL;DR: In this article, the authors analyzed the dust diffusion under several parameters, including the distance between the forced air opening and the cutting face (LY), the height of forced air cylinder above the floor (LH), and the distance from the center of the forcing air cylinder and the nearest coal wall (LJ), and determined the optimal dust control parameters as: LY = 20m, LH = 3m and LJ = 0.6m.

TL;DR: In order to avoid pneumoconiosis and other hazards caused by excessive concentrations of dust in construction tunnels, the authors applies CFD numerical simulation, in combination with field measurements, to study the dust control effect of a construction tunnel under the different parameters of ventilation system.

TL;DR: In this paper, the authors provided a new approach for the structural and parametric optimization of spray dust-settling devices, which yields reliable results using the CFD simulations combined with multi-index orthogonal experiments.

TL;DR: In this paper, a combined method of numerical simulation and field testing was adopted in the interest of solving the problem of hard to control high concentrate dusts on a fully mechanized mining face.

TL;DR: In this article, a combination of numerical simulations and field measurements was adopted to study the migration distribution of the particulate matter emitted by a TRTV at an idle speed for 60 seconds under different movement conditions, and the dilution effects of the ventilation rate on the PM.
