[0002] In the process of coal transportation, especially in open-air stacking and long-distance transportation, a large amount of coal dust will be generated due to the action of natural conditions such as wind. Most of these coal dusts are inhalable dust particles, which can enter the human lungs and cause lung lesions, and even induce occupational diseases such as pneumoconiosis. The workers working in this environment for a long time will suffer serious damage to their health. Therefore, coal transportation dust suppression is an important measure to protect workers' health and prevent occupational diseases. Through the implementation of coal transportation dust suppression measures, enterprises can demonstrate their environmental awareness and social responsibility, and establish a good corporate image.
