使用单斗挖掘机时降低空气含尘量的方法是:采用人工通风将粉尘排离挖掘机工作面;用胶结和增重的方法使飞扬的粉尘沉降,即加快空气介质中粉尘沉降速度的方法;润湿被开采的矿层(或爆堆)中的粉尘。这些方法可以单独使用,也可以联合使用。 可用移动式通风装置对挖掘机工作面进行人工通风防尘,常使用自由风流的通风装置。其供风量及射程,根据采装设备的参数及工作而且来确定,也就按排出有害气体
The method of reducing the dust content of air when using a single-bucket excavator is: using artificial ventilation to remove the dust from the excavator face; using the method of cementing and weight gain to settle the flying dust, that is, the method of accelerating the dust settling velocity in the air medium ; Moisten the dust in the mined ore layer (or buildup). These methods can be used alone or in combination. Available mobile ventilation device excavator face artificial ventilation dust, often using the free-flowing ventilation device. Its air supply and range, according to the parameters of the equipment and work to determine and work, also by the discharge of harmful gases
