TL;DR: In this article, a highly simulated physical model of the goaf and multiple dust sources were established in order to obtain the optimal dust-removal air flow rate in the roadway, by combining the numerical simulation method, the influence of the flow rate on dust diffusion rules of the dust sources was analyzed.

TL;DR: In this paper, computational fluid dynamics (CFD) modeling was used to simulate air flow and dust movement in a super-large fully mechanized mining face, and the results showed that the air-flow increases, decreases, and then increases again during the movement of the working face.

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: An air curtain dust control technology for a fully mechanized mining face was developed, using a method that combined numerical simulations with field measurements in this article, where a triangular air curtain was formed between the shearer and the footway by the high velocity airflow field generated at the outlets of two fans after the technology was applied.
