Owing to the increasing production capacity of longwall mines, dust pollution has become more severe, in particular, in the working area of the shearer driver. Thus, it is urgent to improve the environment of longwall mines. A new onboard air curtain dust control method is proposed, which adopts the idea of partial closed dust control. The improved Euler-Lagrange model is conducted to simulation the dust diffusion characteristics with and without air curtain. The results show that two high-speed air curtains form on both sides of the working area of the shearer driver after the application of this control method. These air curtains can isolate the dust and reduce the dust concentration in the working area of the shearer driver by 69.40%. Simultaneously, the dust concentrations in most areas of the longwall mining section are reduced. Therefore, this paper presents a new, useful method for dust prevention at a longwall mining section.

由于长壁矿山生产能力不断提高，粉尘污染更加严重，尤其是采煤机司机的工作区域。因此，改善长壁矿山环境迫在眉睫。提出了一种新的车载空气幕粉尘控制方法，它采用了局部封闭粉尘控制的思想。采用改进的欧拉-拉格朗日模型对有风幕和无风幕的粉尘扩散特性进行了模拟。结果表明，采用该控制方法后，采煤机司机工作区两侧形成两个高速风幕。这些风幕可以隔离灰尘，将采煤机司机工作区域的灰尘浓度降低69.40%。同时，长壁开采段大部分区域粉尘浓度降低。所以，
