At present, most coal mines in our country are underground operations. Due to the limitation of underground ventilation, the impact of coal dust on the environment and workers is very serious. Every year, coal dust has a great impact on the environment and workers because of the underground dust-proof measures and the inadequate wearing of dust-proof tools. At present, because the underground operators did not take reasonable protective measures and inhaled a lot of dust, it caused great harm to the health. In addition, because the coal dust has not been treated safely, it has caused great pollution to the whole environment, so the effective and safe treatment of coal dust is an urgent matter.<br>This paper analyzes how coal dust is produced, the impact of coal dust on human body and environment, and how to effectively control it, and puts forward the measures that should be taken in each link, dust reduction and dust removal technology. Through the comparison of these methods, a better scheme is selected<br>
