Working Environment and Dust Characteristics in Mining
In the mining industry, the working environment is complex and harsh. Dust is generated in large quantities during processes such as mineral excavation, crushing, screening, and transportation. The dust in mining operations usually contains various types of mineral particles, and may also be accompanied by harmful substances such as heavy metals and silicon dioxide. The particle size distribution of the dust is wide, ranging from coarse particles to fine particulate matter that is harmful to the human respiratory system. Moreover, the concentration of dust is often high, posing a serious threat to the environment and the health of workers.
